ok so i have the 2.8" pulley and the stage 2 kit what plugs should i go with ngk copper or irdiums and should i go one to two range colder or should i just leave the stock plugs?

 

copper and one step colder

Gap to .035 and call it a day

 

k thanks i was just confused cause according to zzp its says use two range colder with a 2.8 or smaller so i didnt know but i think thats what blew my last piston/motor to ****, i had same set up but two range iridums with 60's and a tune ran good for like a month and gapped them .037 .. then one day boom

 

imo most of almost anything zzp touches goes BOOM!!!!

 

lol good one

 

Thats more of a suggestion, real life experience has taught me that the copper step 1 colder plugs are just a great plug. I ran them on my 2.5" pulley on the m62 and on the 2.75" and 2.5" on the tvs. Only at 28 psi did i get detonation and replaced with 2 steps colder to relaize i was just stuck pulling the timing anyway.

Spark plugs are most likely the last thing that will blow a motor, the tune and driver are the two big deciding factors.

 

28psi! dang. lol did you dyno it at all?
