what spark plugs are you guys running ?
I will be running these:
R5671A-7 (stock number 5587)
The reason I'm running these is because I'll have some higher dome pistons installed.

bosch 4227 plugs. $1.99 each, dyno proven on my motor Jeff at IB did a dyno on these also., change them every 10k miles or so. Works great with lots of compression and high lift cams.

Just checked that out a few ago. Rocket is the shizzle. I wonder if he could modify those plugs for me up top.

Denso Iridium Plus Have good Proven Power on FI apps Significant Power gains (FI) but on NA Apps only about 3-4 hp over Stock

IK24 and 0.8mm gap Spoon sells them or you can look at Denso's website for local distributors

Sure way to throw away hp.
I cant count the number of pistons I've used but none have come close to
my spark plugs.

Last I checked, you DONT regap iridium plugs. cant is more likely since they use
the 0.4mm center electrode(which is where the gain is from). Its the same reason
i use the stock NGK platinums is because the 0.6<?>mm center electrode.
You guys think just because copper may be a better conductor that it makes a
better spark, but thats not always the case.

I'm trying to get into the dyno to test these.
In the mean time, it's BERU Silverstones.

I had Denzo Irridiums (SP) until one of them got blown out of the motor. Then while inspecting the damage, another one was on its way out. They were 3 months old. The threads on these things are really soft, apparently. I replaced all of them with NGK plats.
