1 heat cicle colder spark plugs

[fong1]

Hello.

I was wondering if anyone with a 15% pulley, cold air intake and catback has decided to replace the spark plugs for colder ones? Has this worked?

Reason being is that i just got the 15% pulley and some sites say u should place them and other dont mention it.

Thanks

Theres no real gain from these. If you still want them you can get the Denso IK20. helix13.com has them as well
