This premium upgrade is constructed from a single piece of 6061 billet aluminum, anodized black for superior durability and corrosion resistance. It replaces the factory guide with a design that is both stronger and more rigid, offering improved performance and longevity for your EJ engine. A key feature of this timing belt guide is its adjustability, allowing for precise clearance settings. This is particularly beneficial when utilizing aftermarket timing belts that may have varying thicknesses. It comes complete with zinc-coated hardware for secure installation and is finished with a subtle, laser-engraved IAG piston logo. This timing belt guide is compatible with a wide range of Subaru models, including the 2002-2014 WRX, 2004-2021 STI, 2005-2009 Legacy GT, and 2004-2008 Forester XT. Installation is straightforward, with the included hardware ensuring a secure fit. Upgrade your engine's timing system with this durable and precise component from IAG Performance for peace of mind and reliable operation.
