This GoWesty-designed signal filter cable is a cost-effective replacement for the original VW factory part (025-906-302A).
VW originally released the signal filter cable in order to fix the common "highway hiccups" that occur in many Vanagons, essentially "smoothing out" the signal between the air flow meter and the ECU. We had the VW circuit analyzed, and then we designed our own enhanced version, which performs better than the original VW part and at almost 1/4 of the price!
Fits: All 1986-91 Vanagons
