I am selling an AEM CAI for $100 plus shipping. If you are interisted pm me. Or a good offer will be considered. I am also selling a Perrin light weight crank pulley for $85. They all came off of my '03 WRX.

What models will this fit? Do you think it can fit a 98 OBS?

No I think it only fits '02-'03 WRX's. But I am not totaly sure.
