I have a 2007 S2000 with a Rotrex supercharger. Anyone know anything about the Pulstar plugs? (Yes, I did searches but I just came up with one horror story involving Evo's and one with a satisfied S200 application. (NA or FI, I do not know))

Any experiences with these?

 

I have no personal experience, but I have heard nothing but bad things about them. Be careful!

 

Thanks. I have heard nothing but I have a fundamental healthy distrust for things that I do not understand.

 

my tuner had these on a few cars he was tuning and had them melt on the first pull on the dyno. THe electrode nearly fell into the motor. I'd be careful...

 

^How can people make products like that in good concious??

 

Prolly had no clue what he (the tuner) was doing...

 

no, he is a well respected tuner that has done alot of cars.

 

Sounds like Pulstar is complete crap for FI.

Anyone else had any experience/hearsay about them NA/FI?

 

Don't have any experience with them but their comparison tests sound like BS to me. They compare their spark plugs vs ngk, denso iridium and bla bla bla. Then their own spark plugs make more power than the rest. What they don't tell you (read the find print) is that their own spark plugs are gapped closer. Of course they are going to make more power with the gap is less than stock.

Provided that they are physically reliable (which seems like is not always the case), it is dangerous to run these spark plugs on mildly modified cars and obviously on highly modified cars because it affects your timing and we know what the risks are in regards to that. In other words, you'll have to retune. Probably 5-10 minute to retune if you know what you're doing.

 

I don't know but they do it in China all the time.
