Every one I want an answer from knows my car so here is the question. I had it street tuned a little while ago. I'm only on 7 pounds and it wasnt miss firing. Now after a 2 weeks its miss firing at higher RPMs. One of my friends was saying its my spark plugs. I have the OEM ones from when I got the car. What spark plugs would you guys recommend?

 

Anything that I've been around, including my hatch, run just plain old ngk's and gap em around 26-28.

 

I used an NGK Iridium, heat range of 8, gapped at .023. 600whp at 20psi I also make sure, whatever plug I use, it is a resistor style plug.

 

The heat ones I have now are the OEM ones from 60K miles from 2000. Im gonna change them out first thing Monday morning.

 

Cool, those are a 7 heat range if they are stock. Depending on your HP numbers, I'd go 1 colder, but that's just me. I know that 7 psi on my motor would be about 2x stock WHP numbers and I definitely wouldn't use the stock OEM plugs..

 

You must have a nicely sized turbo. Its about 320-330 rwhp. Im gonna get a 1 colder over stock.

 

Yeah, it's a 37r.

 

ngk r bkre7's or somthing like that... cheap and good plugs. i would never spend the money on iridium for when you foul one its not very cheap

oh and thats 2 steps colder, but thats what i always ran for the 1 steps didnt like hot summer days

 

I still cant find what the stock plugs heat ranger is. I think when I go to auto zone ill ask them for stock plugs to find out the head range.

 

Stock is 7

 

no stock is 9? err no im pretty sure on that

 

Stock is most certainly 7. Sorry, you are wrong here. Look up the part number for stock S2000 plug.

Here, I'll do it for you.

oh crap lol im thinking 1.8's 1.6's lol your right it is for sure lol

so you would need to step to 8s

or close the gap down a little

have you pulled your plugs to look at them? but if you have 60k on the originals your due for new

 

I put the new plugs in and it was the plugs. The car runs 1000X better.

 

YAYYYYYYY for kyle!!!
