22RPD Trumpet System Foam Filter (N52 / N51)

A direct-fit foam filter for the 22RPD N52 / N51 trumpet system (velocity stack intake). It keeps dirt out of the engine on a street-driven car, with far less restriction than you'd expect and the same induction sound as open trumpets.

Features

• 60 PPI foam with a stainless-steel wire backing
• Black anodized aluminum base
• Stainless-steel rivet construction
• Stainless mounting hardware included

Fitment: made for the 22RPD trumpet system on the BMW N52 and N51. Check your trumpet system package before ordering.
