What Spark plugs do you recommend??

 

I use the OEM NGK plugs. Have been for over 50k miles, no problems.
I do use the CTSC kit pulley 6psi

 

Use the 2668 BKR8EIX NGK one step colder plugs.

 

I use the same as Moddicition, but I thouight 8EI plugs were two steps colder than stock...or maybe Im running 9's....I cant remember, I havnt seen my car run in 6 months or more

 

These are pre gapped right?

 

Yes they come pre-gapped.

 

Thanks a lot fellas!!! Rep. pts. added.

 

I'd still check them before I installed them.

 

Yes as Modiction recommended 2668. These are 8 heat range, one step colder.

7 is OEM heat range.

Always good to check gap, but yes these are set about 033. out of the box and 9/10 unless your running +450whp with water/meth injection you wont need a smaller gap, these are good right out of the box.
