Road debris can easily damage the fragile aluminum fins on the Impreza WRX intercooler. Minor damage to the fins can effect the ability for the intercooler to cool the air going into the engine, which can be detrimental to performance. Major damage to the intercooler, such as penetration of the tubes that the pressurized air runs through, can cause debris and unfiltered air to enter the engine, potentially causing further damage. Protect your intercooler from airborn projectiles that can bend fins and damange your intercooler This intercooler guard fits stock WRX intercoolers and is made of .035" 304 stainless mesh with a .132" opening. It is surrounded in high-temperature rubber to protect your intercooler fins and includes handles for easy removal for cleaning. Fits MY02 through MY05 WRX; does not fit STi or MY06 or later WRX.
