Twin Airs breakthrough, fused-dual-layer design (now widely copied) combines performance and protection.
The fused layers of open-pore foaming fine inner foam trap even the smallest particles. The new, rounder design and minimised shorter seams boost airflow.
Twin Air filters are assembled by hand and inspected for a perfect fit - Reusing a Twin air filter 40-50 times is common.
Fire Resistant filters have a backfire-resistant foam layer laminated to the filter which eliminates the restrictive, stock backfire screen.
