Just wondering if K&N's cold air intake (63-2571) is worth it?It sounds like cheap power?
Also was looking at throttle bodies.According to Kenne Bell.The GT has a 70mm.You could buy that from your local ford store.Anyone tried this with out tuner?

Read the article linked below. The bottom line was that the K&N worked as well as the other intakes BUT their claim of not needing a tune was bogus. Without a tune the AFR went as lean as 15:1.

Read the testing results at vmptuning.com.

You can not run the K&N gt500 kit without a tune or it will run lean.
