This is an oem top mounted intercooler off of a 2005 Impreza Wrx STI. This is a common upgrade when going from stock to stage 3. It allows a higher volume of air to flow through the intercooler and be cooled. This specific one is in great shape and comes with everything you see here including bypass valve couplers and clamps and the pcv tubing. No returns are offered after the item ships so please make sure to verify fitment before ordering! Thank you!
