colder plugs???

[Jtg1551]

I have a 2004 gp gtp.

I want to run colder plugs in my car, and was wondering what is a good plug to run?

Read thread in my sig.

Alright. Thanks for the advice

Why do u need a colder plug is the question.

[Jtg1551]

Just some small mods. Colder plugs, intake, 180* t state

[Fivefingerdeathpunch]

You dont need colder plugs with those mods.

Sorry i forgot to mention i'm gonna drop a pulley size

[Fivefingerdeathpunch]

Do you have the flow though?

Like headers?

Sure you can drop a pulley size and run a cooler plug, but without flow the motor will go boom.
