The IK22s are 3 steps colder than the stock plugs. I'd go with IK20s if you aren't boosted.

I agree with MrSteve. I purchased a set of Denso IK20 off ebay a couple of weeks ago for about $45 for my N/A '02 TL-S.
I change my plugs every 20k miles which is probably a little too ofter. But I like tinkering so it gives me something to do.

Thus IK22 two steps colder.

Beyond that, I'll check the PCV valve and maybe tune the car on the dyno again.

any thoughts on which plugs i should run?
99.5% of the time my car runs n/a, the other .5% w/ nitrous. should i still run colder range plugs?
my car has been running pretty rough on startup lately and i think it's time to get rid of the zex plugs and go w/ some iridiums.

take off your intake manafold and clean it out along with the EGR port with some carb cleaner - that solved the rough idle in my car 100%. My EGR port was nearly all the way clogged up with carbon

Run the IK20s or IK22s.
Remember, 90% of the time with the SC the bypass valve is open so we aren't seeing boost and I never once had a start up issue with the SC'ed car while using the IK22s. (With the UniChip I did though).

Are NGK Iridium plugs just as good as DENSOs?

Maybe this was answered already but would would it be safe (and effective) to install the IK20's in a n/a type-s straight out of the box or should they be gapped?

sorry to butt in on a 2nd gen topic, but what would guys suggest for a n/a 1st gen 2.2, IK16's or IK20's? or is it even worth it to spend this much on plugs?
