^ the dyno results on that v8 weren't terribly convincing. however, given the import tuner dyno and subsequent write-up on the civic si test mule, things still looks promising.
anyone actually use these on their tsx yet? any mis-fire issues?

As long as the spark plugs perform as it says, there should be a noticeable difference in drive and possibly power output at peak.
I had used Nology products, in particular the cables and the capacitors discharger and it certainly worked very well on H22A 1st generation Euro R JDM.
Thus, this is why I am also keen if these plugs work with stock direct firing cables. Because it the stock direct firing, it is actually a guess work which cables to actually cut and add in a spark atomiser (to generate higher current for sparking)
there is an alternative, which are the electrical firing heads are subsituted with a Jap aftermarket (cannot recall the brand) and this option is expensive for the K20. Between NGK and Denso, there is already a difference of driving...NGK seem more torquey and Denso more refined. Strangely enough, denso has very fine tips and attribute to this firing refinement??
A bigger and powerful spark actually makes smoother driving and in particular, if it can take the heat at Vtec range, then it would be a good plug. Oh yes, I drive a JDM Euro R, so, my comments to note for K20 engine. My previous ride was CL1 JDM Euro R (first generation on H22A 6th generation engine)

hey, Pulstar replied me on my JDM Euro R specs and hopefully I can get a set and try it out. I have tried so many different spark plugs Denso, NGK, Nology blah blah and they have in some ways measured differently in behaviour. If it does what it says it is suppose to do, i will share it here.
We tested an Extreme Spark that is supposed to increased the eletrical discharge to stock plugs. It feels a lot more responsive. If Pulstar Spark plugs is similar, i will be satisfied.

I heard no further from them after I asked them how I can pay them. Maybe they realise I was on the other side of the world. Seems like they recommended be BE-1 set, what will be your set model number?
By the way, let me know if this plugs work. Else, I would have to set up a barter trade with you and get you what u need from my side. We have various replica stuff but shipping bumbers and kits are a real butt pain due to loose cargo and size...

what funny is i dont think i have heard one person say they have them.. kinda would like to see if they are as great as what other peoples vehicles say they are in them

My post above, this is one option of plasma direct that I was considering but it is expensive. What it does is basically building up the current for a bigger discharge i.e bigger sparking.
In principle, it is exactly what the old firing coil with an added current amplifier does. It should work well these plasma directs. However, there is the current spark plugs which could hinder the impedence. Thus, if there is both plasma and the less resistance spark plugs, it maybe the best combination.
I hope to get a set of these pulstar plugs and see the bahaviour over stock, before I re-consider the plasms direct. Could ab an overkill to have both.

I had a distant conversation in Hong Kong and he sweared by the improvement with the Plasma directs. In principle it should work, but comparing these sets vs using an current amplifier, the pricing is gap is huge!
So, hoping to try out the pulstar plugs as another option. But it would seem hard as Pulstar has not replied me yet on details of purchase. Damn...

just picked up the lated edition of import tuner at the grocery store. they tested the plugs on a 2008 lexus is250 6spd. peak gains of 1.7hp and 2 tq, gains were realized across the board!

I bought these this summer! They sent me the wrong gap size they were all diffrent! Bad Company! They refunded my money tho! But still I shoulda got free spark plugs I didnt even get to try them out. And yeah missfire

Pulstar’s capacitor energizes the spark much the way a camera flash energizes light. The visibly larger spark has a much higher power density than spark plugs and ignites fuel more precisely resulting in better combustion efficiency. It is sort of like putting a flash bulb in your engine. Like a camera flash Pulstar generates the additional instantaneous power without utilizing more supply power.
All you're burning in an internal combustion engine is gasoline. Gasoline has a given rate of ignition, which doesn't change depending on the amount of energy in the ignition spark. Fuel ignition is fuel ignition. There is no more precise ignition or less precise ignition. It is either ignited and burning, or it isn't ignited. Multiple flame fronts will achieve a faster burn of the fuel in the chamber, but that will royally **** up your engine. Combustion efficiency is a function of the fuel being burned and oxygen availibility. How does your spark plug alter either of these? (Mechanical Engineer of 11 years with a graduating GPA of 3.97 so I probably know what I'm talking about since I make a living figuring out things like this.)
Let's look at that camera flash analogy. Every camera flash in existance needs a little "recharge time" before you can discharge that capacitor again. Driving down the road, you're probably turning the engine 3,000 RPM? That's 50 revolutions per second, and 25 ignitions per plug per second for a 4 cycle, 4 cylinder engine. That gives this camera flash 0.04 seconds to fully recharge and fully discharge. At 6,000 RPM, that's 0.02 seconds. I'm calling BS on this one. Doesn't work the same way camera flashes work.
And come on! CEO of the company who coincidentally drives an Acura TSX. Been watching this post closely but has only made 5 posts since September of '08. PPFFTTT!! I'm calling BS again.

Seriously, u should do a combustion efficiency test with various plugs set up, Direct Firing and old school mechanical ignition firing.
Because that the engine is running higher rpm, the efficiency lags due to speeded up firing consistently. To compensate for this, some ignition firing is "prolonged" for a more complete ignition of gasoline & air.... Various parameters, temperatures to less volatile accuracy mixes, defficiencies drop due to wear & tear etc.
Ths, if it is at all possible, having a larger spark (plasma type) to various mechanical research of optimum tips sizes to various engines ECU mapping, generates a better ride (smoother, more complete, more "efficiecnt" etc), indeed would have improved over stock.
The yield of the spark plugs success, is minor, however, let's keep in mind that we are talking about Normally Aspired (N.A) engines and every yield of HP and torque gain (depending on the curves of gain achieved), is every small step towards optimum efficiency.
My point is that all mechanically derived systems are developed with a certain so called optium efficiency and once usage starts, it is down slope loss of efficiency. Thus, any replacement/add on etc that could bring it back to original efficiency...no matter how little for N.A cars, is already something I would value.

Keep in mind that they are supposed to be good for 50,000 miles. $150 may not be much for a one-time purchase, but I wouldn't want to have to spend that for plugs every 3 years or so.

i got my plugs in today. actually i should've had them a few days ago, but i was never home to sign the signature pickup.
anyways, I WILL DO A BEFORE AND AFTER DYNO

i'll dyno sometime next week with before and after dyno charts specifically for this thread. if i don't make power, then wtf am i gonna do? where could i get ngk iridiums for the cheap

- seems as if the pulstar plugs LOST 1hp across the power band (we had to use a different dyno than last time due to a scheduling conflict)
- however, we did 3 runs prior to the plug install and then 2 after so car may have been a bit hot
* the oem ngk iridiums looked like they needed to be replaced
- avg runs of pre and post pulstar plugs are reflected in the chart below (line with the higher hp numbers are old ngk's)

I mentioned earlier in this thread that I had doubted the benefit of the pulstar plugs on an engine which uses direct ignition. There isn't a "problem" for the pulstar plugs to fix.
