Thread: Which pulley size will work with my car?

Still need cooler plugs, and probably a better tune than ZZP.

When you deside to order your pulley, get the modular pulley system with the 3.4 and have it scanned for kr, if you have some move up to the 3.5 and sell the 3.4 and make some money back. But, yes like Sabre said, get some colder plugs.
