do the 2006 Revup motors have a powerstack in the intake? just curious cause im debating whether to get a JWT popcharger or just throw in a drop in air filter if the intake cant be improved much by a cone filter or new intake system.

 

Yup, they have a velocity stack.

 

yeah...so just opt for K&N filter and save the other 120 bucks for something else? like test pipes?
