Just wondering if there's a Cold Air Intake that approved by CARB? I did my research so far the brands I found out are states CARB Approval pending or not approved.

 

Af1 ?

 

K&N Model 57-2556 is CARB Exempt. I have on installed in my 2005 Scab 5.4. It even comes with a little CARB Sticker. It is an easy install.

none of those are true cold air. they will suck a lot of hot air from the engine bay and reduce power gains. having gone through both types of intakes, there are significant observable differences

volant, S&B, and outlaw are CARB approved intakes. unfortunately outlaw does not have a 5.4 model yet.
