I'm having some idle troubles with my 05 wrx. I need to order a new iacv. The part # on the one in my car is 22650aa182 that oem part is $280 and up on eBay but I can get a oem 22650aa181 for only $70 on eBay. I like $ and don't feel like throwing it away on ridiculously marked up parts... Is there any differences between the two?? Any help would b awesome!!!

 

Have you already tried cleaning the valve? The shutter should be able to spin freely with just about no friction/resistance.

 

Yeah I cleaned it as instructed in other posts and replaced the gasket already but it did not seem to help... I had my buddy test the O2 sensors and there working fine we also smoked the intake and exhaust so I'm pretty sure I need a new aicv.

 

I'd also like to know the answer to this cause my is shot too and needs replacing.

 

Its the same item, part number changed. 22650aa182 is the newer number. Gasket is #22659aa120 also if you need one
