I have heard from many people that getting Denso Iridium SPark plugs help quite a bit for the speed. Does anyone know waht this will do to our warranties or what pulleys will do to it also? Thanks alot everyone

I just got the BOSCH platinum+4 spark plugs. I noticed a nice increase in throttle response and acceleration. ANyone else have any experience with the BOSCH platinum+4 spark plugs?

Did you notice any problems with your spakr plugs or just a nice gain in HP or was it a very little gain. Im reallying considering something for my car in addition to my intake and sways i just ordered and someone told me to get sparkt plugs or pulleys but then i have heard some shady stories about them doing things to mess up your car in the end.

Well AirC, I told you it will add power, but you never trust me.... see this for yourself then... This is only for the Accord, with 3.2, you will see more power from those plugs.... One thing, when you car is stock, you won't see as much power gain, the more mod you put on, the more power you will see from those plugs.... Well see ths for yourself then since you never trust my words!

I had the Bosch Plus 4s in my accord and they definatley made a bit of a difference in power, but also in fuel economy. I checked into the plus 4s for the type s and they were not made for it yet. I might think about the Desnos as well--that dyno was pretty impressive!

Denso plug are factory for the gs.
I thought the bosch +4 would have been better, but after checking with the experts the iridium are the best. Iridium is a much stronger metal than Platinum with similar properties.
But just to let you know:
Bosch +4=$5/plug
Desno Iridium= $9-11/plug
It is not going to replace an intake upgrade as far as hopepower, but my reduce the chance of pinging.

Just a side note about his headers. I talked to the guy Sat. night. He had his headers jet coated and they fucked it up the first time and he sent it back. Apparently they put another coat on over the existing one. He thinks that may be the cause of not seeing the performance increase he was expecting. He has the dynos for every mod he has added.

One thing, I am sure is not in the book, so don't quote me on this.....

My uncle, used to be the president of Nismo in Hong Kong division, also my mechanic teacher, who taught me how to work on my Nissan. He worked with cars for 30years. He said one thing about the torque wrench....

He said, NEVER use a torque wrench to torque the spark plugs, and also some easy to break parts.... The reason is, cuz when you using tools, you can never feel the real torque from a tool, also, you never know if the tools is working or not. With things important like spark plugs, if you screw them too hard, that's it, you can never go back....

He said AlWAYS use your hand to screw those plugs in softly, to the point where the plugs stop screwing in, then just turn 2 degree more. THAT IS! That's the best torque to the spark plugs, and it will NEVER come off....

With tools, you set them to a certain torque spec, but that doesnt mean they are accurate, and only newbie mechanic use them.....

BUT of course, different mechanic have different theory, but I trust my uncle's word. So if you don't think so, don't flame me! hehe!

FYI, when installing spark plugs, always apply a little "Never Seize" compound to the threads before reinstalling. This will make it easy to remove the plugs. NEVER, NEVER, NEVER over tighten spark plugs.

I don't normally post here but a friend of mine lurks on this site and told me about this thread.

My headers dyno'd a 6-7hp increase, See for yourself, The Red graph is with the headers and the blue graph is without the headers. My car shifts at 6,200 rpms so that big spike around 6,400 isn't a legit peak reading.



Why would I falsely say my headers sucked and I didn't feel any gains after I spent over a $1,000 for them, then another $250 to have them coated, and then another $225 to have them installed? Accords don't get 32hp increases from headers! The best dyno gains we have seen yet were about 15-18hp but that was with a Randomn Technology hi-flo cat, AND the headers. That was on a 98.

The shop I go to actually dyno's my car 2-3 times BEFORE the mod, and 2-3 times AFTER the mod is installed. However, reading 6 graphs on one prinout gets very cluttered, so I just have them print the best graph before and after the mod. I'm present when my car is dyno'd and I see every graph so I know they didn't pick a crappy reading from before the plugs, and a good reading from after the plugs.

My car has been dyno'd about 23 times since I started modding it! So far I have done intake, pulleys, headers and spark plugs. You tell me how many dyno's that is for the mods I have done so far. If DynoJet would get off their azz and release an updated dyno viewer for the PC I could post graphs of EVERY dyno run ever made on my car. The shop I go to saves all the dyno runs on their PC so I can just d/l them to a disk.

I love CompTech to death... if I ever wanted to forge a fake dyno, it would be for their headers! I would love nothing more than a dyno chart that shows a 20hp gain from CompTech headers, but that didn't happen!

Why is everyone so convinced that whenever they see a dyno that goes against convential wisdom, it has to be fake, or something can't be right.

Put your money where your mouth is and you spend almost a $350 in just dyno costs and then come talk to me!

Everyone always likes debunk fact with theory. My dyno charts are fact, they aren't fake, not some kinda made up theory... they all happened. You guys in Houston are more than welcome to meet me at Carboys the next time I have my next mod done so you can lay out your 20 step scientific method necessary to ensure a 99.9% accurate dyno session!

You can't understand how frustrating it is for me to do these dyno's and people cry foul everytime it doesn't jive with what they think. When my headers were dyno'd I had people try to tell me the DynoJet must have been bad, because I *HAD* to get better gains thatn just 6hp.

I don't just Dyno my mods, but I also test them at the track as well... I have close to 50 times slips from 3 different drag strips!

That's not a problem. The comparison was done with stock plugs vs new plugs. I would be more than happy if someone from this site would take the time and money to post a dyno showing new vs new plugs. Honestly though, do you think someone would buy two new sets of spark plugs just for testing purposes and only use one of them?

Quote:

<font face="Verdana, Arial" size="2">1. Our cars tend to increase HP with each pull. Mike, a fellow member, had an earlier dyno, and each "pull" was higher than the last. (He did the work, and if you like I can probably dig up the graph.)</font>

That is why I do multiple pulls before and after and you are correct. From my experience gains will go down after too many consecutive pulls since the engine seems to heat up which hurts the air/fuel ratio and thus power.

Quote:

<font face="Verdana, Arial" size="2">2. I've put in plugs after 10,000 miles, and felt a difference. So, if you don't compare the "factory NEW plugs (out of the box)" vs. "the Iridium or other NEW plug", what have you proved?</font>

I've proved that anyone with aproximately 33k miles or more on their stock plugs should see a healthy gain with Denso Iridium spark plugs. How many people here have changed their plugs before they drove the car off the lot?

Quote:

<font face="Verdana, Arial" size="2">The issue is not with the dyno, it is with some clarification. If you have stumbled on to something that gives better fuel economy, more power, and is factory sanctioned, I'll be the first in line to thank you.</font>

My issue is with all the assumptions that are made when people don't bother to read what I have posted to clarify, or for not asking instead of just making assumptions. I'm not singling any one person out but you can imagine every time I've posted a dyno chart, I go through the same thing, so it gets frustrating after the 5 or 6th time.

Quote:

<font face="Verdana, Arial" size="2">I can only speak for myself, but I've seen a number of claims made for products, with supporting info, that on further investigation, turns out to be bogus. If we lived in a perfect world, and everybody was "perfect", there would be a need to question anything. </font>

It is BECAUSE of all the dis-information by other members and manufacturers that I do dyno my car before and after every mod. Go to any import shop and ask them how much hp you will get from a universal muffler! I've had people tell me 15hp.

Quote:

<font face="Verdana, Arial" size="2">If you would like to clarify the nature of the "dyno" test vis-a-vis the plug vs plug AND if both sets were "brand new"/out-of-the-box, then I would be most appreciative.</font>

Already done.

Quote:

<font face="Verdana, Arial" size="2">As a note, I would expect that as more dynos come in, that some combination of mods will work and the result will be equal-to or greater than the individual parts gains. There will also be some cases where two parts that work well by themselves, when put together, will return poor gains or even losses. (I'll spare you the details, but it has happened to me [on another car].)</font>

I agree 110%! That is why I wish more people would dyno their cars instead of trying to put down everyone who posts their dyno charts. The only way we can learn is by gaining information. If people don't go to the track or dyno their cars then we have learned nothing at all, except that "WOW, it really felt more faster!" (improper grammar intentional)

Quote:

<font face="Verdana, Arial" size="2">Finally, you are the ultimate beneficiary of your own work -- isn't that benefit enough?

Not really, if I only wanted to benefit myself, I wouldn't come to message boards and try to help others... my goal is to learn as much as I can and help others in the process, like I have been helped and hope that others will follow my footsteps and do the same.

Before anyone gets to carried away with claims and counter-claims about what the HP gain should be with Comptech headers, let's remember that the gains for the CL-S tend to be more than with the TL or Accord. By the same token, the gains from the exhaust systems tend to be less with the CL-S as opposed to the Tl or Accord.

WebToker

I just put Denso Iridium plugs on tonight. WOW!!! You can feel the gain like night and day. Car seems to respond quicker and overall has more power. Anyone that was thinking about getting these, go get them. They are well worth it. Took me about 1hr 1/2 to install.

I would say I noticed as much or a little less than the intake. I was very very suprised. I mean shit, they are just spark plugs. I would get that at CarBoy, they were about $90.

Did you find a comparison on how long they last compared to the Densos? From what I have been told the Densos never have to be changed.

From what I have been reading... slow day at work... it should last longer than platnium. Also found them for 12 a piece plus shipping at monarchproductsinc.com. The denso site has someinteresting info. Overall alot of people seem to be pleased with them. I probably will have them put in at my next service.

How many miles would you guys recommend that you have on your car before putting in these plugs? I only have 1500 miles on my car.

I totally agree! If I had access to free dynos, I don't think I'd ever drive my car anymore but just spend all weekend trying out different products and comparing gains.
Well I know that the top fuel drag cars, are rebuilt after EVERY run! That is probably done more for safety than performance though.

Well I appreciate your being polite even though I came on a little strong in my first reply. Its nice having a discussion instead of an arguement.

buddha

Was the 90 you paid including tax and stuff at carboy?

WebToker

Ya something like that, may have been $91.

scalbert

BTW guys, it take a minimum of 5% gain to actually begin to feel it. Many times upwards of 10% depending on how the gains come in. Anything in the 2% range is just out of hope, even if gains are there.

In fact, some of my faster times at the track actually felt slower than previous one's. Plus, gas quality can make a noticeable difference. Heck temperature and humidity changes will affect you can more than many mods will.

WebToker

All this is common knowledge, and is why I was so surprised. The car feels like it has more power. I couldn't believe it at first.

Dang Calvin, you didn't waste any time. Oh, I won't be able to make it Houston this weekend. Daylight savings change is on April 1st, and the last time the time changed, the computer operators at work really messed up one of my applications and it took me 3 days to straighten out the mess.

Okay, I just blew 89 bucks for the plugs. I bought them from Tim because I think he has been very responsive to aftermarket parts for us. Those dyno's were pretty convincing along with Webtoker's testament.

Webtoker,

Was it difficult to install? Was looking at the engine this weekend and notice that the back three plugs are sort of hard to get to. Especially with the strut bar in the way. Did you take the strut bar off? Any thing else you can tell me about making the install easier? Thanks.
