Manufacturer:

$34.99
$29.99

Made to high standards, these covers are designed to extend the life of your air intake filter while also giving you a way to visually see the amount of dust collected.  The covers work equally well on both oiled and non-oiled filter elements to prevent larger debris from prematurely reducing critical air flow to your engine.

Installation Note: Take care installed over filter elements with metal cages as a metal snag can tear your cover.

    Nice cover , it will keep the big stuff out and protect my investment.
    I may restrict some air flow but barely noticeable, looks cool and works a treat.
