Impreza sti secondary air valves


Recommended Posts

Theres not really a cheap fix assuming they are the problem. Moisture gets in and causes them to seize. You have two options,

1> get them replaced

2> get them removed and get the car remapped to run without.


Prices are prob similar to be done properly, map option will solve the problem long term. secondary air system is only used for about 30 seconds on cold start for emisions compliance.
