I have the K&N drop in filter and Helix throttle body spacer. I’m not sure if I notice that much of a HP increase. So should I take off these modifications that were put on when I received the truck and install an intake system? If so, which brand of intake system? Some of the reviews that I read said that the Throttle body spacer was a waste along with the drop in performance filter. I want one that will give me the most HP for the money. I emailed K&N and asked them if I’d have to remove my Helix throttle body spacer to install the FIPK intake system and of course they said yes.
