GrimmSpeed Enlarged Bore Intake Manifold to TGV Gaskets Subaru WRX 02-14 / STI 04-21 | 023001

These GrimmSpeed enlarged bore intake manifold to TGV gaskets are a game - changer for your Subaru. They fit 2002 - 2014 WRX, 2004 - 2021 STI, 2005 - 2009 Legacy GT, 2005 - 2009 Outback XT, and 2004 - 2013 Forester XT models. The OEM gaskets have a much smaller hole diameter than the TGV, limiting port matching. But these gaskets have enlarged ports, allowing perfect alignment of the intake manifold and TGV. This greatly enhances air flow quality right before the air enters the engine. You can pair them with GrimmSpeed Phenolic Spacers. They are installed at the intake manifold to tumbler gasket location, designed with enlarged bores to match the OEM TGV diameter. They provide an optimal seal and help improve airflow. They are sold as a pair.

Using these GrimmSpeed gaskets is straightforward. First, make sure your engine is cool and the vehicle is parked on a flat surface. Remove the old gaskets from the intake manifold to tumbler location. Then, carefully place the new enlarged bore gaskets in position, ensuring they are properly aligned with the ports. Double - check that they fit snugly. When it comes to maintenance, there's not much you need to do. Just keep an eye on them during regular engine checks. If you notice any signs of wear or damage, such as leaks or cracks, it's time to replace them. Also, remember to handle them gently during installation to avoid any accidental tears or bends.
