I'm looking at either buying a K&N FIPK or a JLT RAI. I know a 75mm throttle body will fit on a JLT, but will a 75mm TB fit on the FIPK? Is the FIPK's diameter large enough to flow enough air for the 75mm TB? I'm just trying to make a purchase that will allow me to upgrade to a 75mm TB in the future. Suggestions???
