Does a new air filter really add that much performance. Do you notice any gains with say a K&N filter. just currious

 

i found it makes a noise difference but it only put out like 1-2hp for me, others may think different but thats what i found...Its more about adding the different elements up..filter goes with exhaust that goes with power commander that goes BOOM!!!!!

 

yeah..i could'nt really tell e diff..but what i can tell is an increase in of 4rwhp with gp force slip-on,v stacks and BMC filters.

Current modifications done..remove flapper and cut off the fins in the air duct..cut off the catalytic converter. Awaiting the arrival of my serviced PC III b4 having it remap again and see hw it goes..

 

just added k&n today well see in a few days if i notice
