Sparkplugs
Will using SS/SC Spark plugs in my 2.4L on spray work?
If not, does anybody have a park number for colder plugs. I'm running a 50shot on my SS 2.4L and the car boggs at high RPMs.

well, I'm thinking the SS/SC plugs, since the car brings forced induction from factory.
And with any power adder such as turbo, SC, or nitrous... you need colder plugs.

These are NGK Iridium IX numbers, for a 2.2L Ecotec J-Body. When I last looked, there were no other heat ranges available for the 2.4L but I found these. Since we run the same stock plugs as the 2.2L Cobalt, which also has the L61, I didn't see any reason why they wouldn't work.
LTR5IX-11 - Stock heat range
LTR6IX-11 - 1 step colder
LTR7IX-11 - 2 steps colder
