For fabricated intakes or a worn element on an existing setup, this Airaid oval filter takes a 4-1/2in flange. The SynthaMax media is a dry synthetic, so it is cleaned without filter oil.
Airaid sells it as a replacement element for its intake kits, and it can also be used as a universal clamp-on filter.
