Dual Cone Air Filter 3.5″

Dual Cone Air Filter 3.5″

More filter area means more airflow — and this Dual Cone Air Filter 3.5″ delivers exactly that, with a smarter design that leaves flat-end-cap filters behind.

Why the Dual-Cone Design Wins

47% More Filter Surface Area

The signature dual-cone end-cap geometry is not just a look — it increases total filter area by over 47% compared to a standard flat end-cap design. More surface area means less restriction, plain and simple.

Higher Airflow Volume

With intake restriction reduced, your engine pulls in a greater volume of air. Whether you are building a custom cold air intake on a naturally aspirated setup or upgrading an existing CAI, the difference is immediately noticeable.

Improved Intake Velocity

The conical shape does not just open up flow — it shapes it. Air moves through the filter with improved velocity, so what reaches your throttle body is doing exactly what a performance intake should.

Universal 3.5″ Slip-On Fit

Designed to slide directly onto a 3.5″ round intake pipe, this is a true universal high-flow air filter ready for custom builds across a wide range of vehicles and applications — gas, diesel, street, or track.

A Real Upgrade from Flat-Cap Filters

If you are currently running a regular flat end-cap filter, you will feel the difference. Less restriction, more flow, better velocity — all from a direct-fit swap.

Stop leaving airflow on the table — upgrade your intake build with the performance filter geometry that works harder than any flat-cap design can.
