Gates Cam Idler Sprocket Subaru WRX 2002-2014 / STI 2004-2020
When doing a timing belt replacement it is always a good idea to replace the tensioner(s)/idler while you are in there. With the Gates Timing Belt Tensioner/idler you can rest assured knowing you used a great part. Gates makes many OE parts and their aftermarket parts exceed OE specifications.
