Coil on plug, you can replace the boot but I wouldnt replace it until the coil starts to go bad.

 

@RobSS. Am getting ready to change plugs and was considering going a step colder. Did you notice any improvement by going to a colder plug? Have the GMPP kit on a 2009 SS auto.

 

I believe we have coil packs. High performance engine and what not.

I am very familiar with the in's and out's of these little cars. Especially the 2.0 turbo or LNF engine.

If you stay around this forum, you'll learn that I sometimes will have an odd sense of humor (or sarcasm) in my posts.

 

I will have to watch for that

That is that new secret mod that isn't well known yet, you take the COP off and add wires. All the fast SS guys are doing it
