I was about to buy a JWT Pop charger, then I saw some K&N drop in filters for the stock air box. I was wondering if anyone knows what the power gain differences are between these two. Is most of the power gained from a pop charger from a less restrictive air filter or getting rid of the stock air box?Thanks.
