The IAG Performance billet timing belt guide is the best method to prevent your EJ engine from skipping a beat. Each guide is machined from a single piece of 6061 billet aluminum and then anodized black for a protective finish. The guide is a strong, rigid replacement for the OEM piece and also is adjustable, enabling you to set proper clearance for the timing belt. The adjustable feature is especially useful when switching to an aftermarket timing belt where belt thickness can vary. The edges of the guide feature a soft corner that prevents wear on the flat side of the belt. Stainless steel fasteners are included.
Fits all EJ20 and EJ25 Subaru engines, which means 2002-2014 Subaru WRX and 2004+ WRX STI.
