So i was told recently that i should only put NGK plugs in my car and about a week ago i put some boschs in the guy told me i should take them out right away so i guess what im askin should i go grab some NGK's and replace them or will the bosch's be fine

 

Bosches will be fine, but I would maybe change them a little sooner than later (maybe 50-70, instead of 100,xxx)

Kind of like putting lower premium gas in your car. You dont have to syphon everything out cause its going to blow up, but you will get better performance with the good stuff in there.

Not really sure how much of a difference plugs make though, but just to be safe I would consider the NKG the stuff to have

 

Acura approves 2 brands for a reason- our hi energy ignition and bosch plugs are not a match!!!
Denso cost more and last less mile, so NGK Iridium are what is stock in the car and the best choice replacement at this time.

Yank the bosch now and return them as wrong item
Install NGK
Enjoy

did your buddy say seafoam is bogus too?

 

IS seafoam bogus??

 

no if he said seafoam is bogus i would have slapped him i think the stuff is great

 

seafoam is only bogus if you are able to totally disregard ALL the instructions here saying slow slow sip sip is the way to get it in the vac port---
and you dump a full can in the intake vac in 5 seconds...the engine stutters-stalls and backfires, dousing you in seafoam,,

but you really have to try hard to do that

But get the bosch plugs out- other members ran them for a few months then reported better running car when put back on the proper japanese plugs for japanese cars!!!
Bosch goes in bmw~ I replaced many hundreds of them over the years

 

I had denso before, it cost me more money and lasted only about 30k. I then put on NGK iridium. I would not put anything else but NGK-i from now on. The NGK is said to be able to last about 40 to 50k.

I would go with NGK-i.

 

i think it works really well, its the cheapest and easiest way for a quick tune-up...especialy since you're supposed to change the plugs shortly after the seafoam treatment as well as your oil. if you need more info let me know

 

you need more info!!!

there is NO need to change the plugs after foam unless you have high mileage plugs AND you fail to do the after drive- then you will carbon load the old plugs and need to replace.
Most of us have over 70k when we foam so we go ahead and do the plugs
If you do the oil- then you need to change the oil and filter

 

i should have been more specific when i said change the oil and mentioned the filter as well. i thought that was common knowledge.

i didn't know about the carbon loading on the plugs without doing the drive afterwards. i agree don't change them if they're not high mileage tho

 

failure to do the afterdrive will usually result in fouled/loaded plugs, thats just basic science

at 30k I would not worry- at -70k miles I foamed and changed my spark plugs

 

Off topic just a bit but what is the ultimate, finite purpose of doing the seafoam process? What is the ROI?

 

read the can! or google or wiki or seafoamsales.com

it dissolves carbon-glaze-crud buildup in the carbs/injectors, cleans the intake valves (better fuel distribution to the cylinder), and the piston tops (better combustion on clean surface)
So basically- its tune up in a can--that really works- since 1940!!

In the oil, it dissolves buildup in the oil passages, cleans the piston rings (better seal) and all the tiny ports oil goes thru get a good scrubbing
My oil filter was full of crud after 150 mile drive with seafoam- on a new filter~

 

so when should you add the seafoam, before you change the oil or after? also i am currently running the bosch's as well, is it really that big of a deal, you think im losing hp?

 

I changed the original plugs in my 2001 TL at 110,000. They were NGK's and still looked great. Why do anything else than what is recommended?

 

bosch are not friendly with our ignition system

Acura allows 2 brands- for a reason- designed to work with the japanese engine designs.
Everyone who has changed back to the correct NGK Iridium plug.. found increased mileage, and it ran like a TL again!!

Plugs may appear fine visually, but the reality of how they work- performance starts downhill about 60-70k miles, and the book says replace at 105 with the timing belt- assuming normal service duty- but look at the book and many drivers are in the severe duty list of car use

Replacing them early will not hurt and should improve mileage- the payback~

 

The bosch is fine.Actually,its one excellent brand of spark plug.That guy is just jealous.Or if he is a mechanic,he just want to make some $$$$

 

No- its proven on the TL by members of this forum
bosch does not work correctly and will wear out fast!!!!
NGK last longer than the other apporved brand- Dendo- denso also cost more!
Acura put NGK in there for a reason
Every japanese designed car or motorcycle I ever worked on had NGK as stock and replacement plug

Only cars I ever saw Bosch in was BMW's and certain other Euro cars
Oddly enough- my american vehicles have always come with/approved champion or ac.
go figure

But the FACT remains- users here have switched back after a few months of deciding, and found it ran better with NGK Iridium

I still get a laugh at the OP statement, knew to buy ngk so installed bosch.....tff

 

I replaced the OEM NGK's again with NGK's in my wife's Honda Pilot at 105K and the originals looked great also. Amazed on how sharp the center electrode was, only very slight insulator discoloration, the only extremely small deposits were on the outer barrel.

 

I think the issue with the Bosch Platinums is the extremely fine center electrode get erroded quicker than the Iridium electrode of the OEM NGK's. I have used the Bosch Platinum's on older Honda/Acura's with great results but I suspect those car's iginition output is not as hot as modern ignitor/coils.


Since you only have to change the plugs every 100K miles it only makes sense to get the best plugs in there. I've seen the OEM NGK's at 105K miles on a J35 motor and they look great.

 

Its about the TL having coil on plug ignition- very high intensity

 

Oh and one other thing i was told when i got spark plugs to get a heat grade higher is this a good idea

 

who are you talking to to get this bogus info ?????? well- stop it!
they are not in tune with the TL needs!!

read the owner book- if you are running long distance hi speed trips only- then a step colder plug will last longer and work better for you

For all other normal operation- stick with what the book/underhood sticker calls for.

This does not apply to heavily modified-turbo-s/c cars of course-
but you guys know what plugs to run!

 

This is why i ask things on here before i do it because im pretty sure you guys know a lil more about this stuff than i do

 

More than your friends do for sure~
Check the owner book- then here, for any specifics on maitenance

 

Just follow the recommendations. Why would Acura recommend the WRONG plug? Sheesh!

 

at the shop i work at, every car we've put bosch in, they always come back with a missfire. ngk platinum is the cheapest we ever put in. PLEASE put the NGK's back in!

 

i was running boschs for about 3 months and my car felt like it wasnt running smooth from 3 to 5k rpm, i switched back to the ngk's and it runs smooth and pulls hard again.

 

there we have it!!! use the correct plugs,
and get smarter friends or ignore the current ones!

btw- the only plug heat change you would do is colder, for long hi speed trips
