Injen SuperNano-Web Universal Air Filter - 3.5 in Inlet, Twist Lock

Injen's SuperNano-Web is a dry universal air filter that layers a nano membrane over a high-flow base media, trapping fine dirt and dust without the filter oil that fouls a MAF sensor. The conical closed top element stands 6.50 in tall on a 3.50 in inside diameter twist lock flange with a 5.50 in base, tapering to a 4.0 in top, and carries 5.15 in of deeply pleated media. Integrated ridges in the flange seal against the intake tube and a stainless steel band clamp with an inner protective liner holds it in place. The filter is fully serviceable and cleans with a light blast of compressed air, no re-oiling needed.
