There was a thread on this already (3 years ago) just wanted to see what everyone thinks now-a-days....
OLD THREAD

Which plugs would be best for an ECOTEC...im running around 10PSI

NGK's are as follows:

NAME Part# Stock# PLUG GAP
G-Power LTR5GP 5019 .044
OE Laser Iridium ILTR5C11 ^ # 5581 .044
Iridium IX LTR5IX-11 4344 .044

also what year srt-4 plugs? does it matter?

Thanks,

2 steps colder = LTR7IX-11
stock #6510

1 step colder = LTR6IX-11
stock #6509

Use srt4 plugs at your own risk. They are supposed to be longer than stock. However, some people have used them with good results, some with bad, or worse.

I use the 2 steps colder for my S/C 03 cav.

Thats where I got the part numbers.

Im running NGK LTR6IX-11(1 step colder) in my S/C ecotec cavalier. I am also at 10psi. I can conferm that the LTR6IX-11s are the same length as the stock ACDelcos.
