Fitment Information: This product is a perfect fit for a wide range of Subaru models including the 2002 - 2021 WRX, 2004 - 2021 STI, 2013 - 2020 BRZ, 2005 - 2009 Legacy GT, 2005 - 2009 Outback XT, 2004 - 2013 Forester XT. It also fits the 2013 - 2016 Scion FR - S and 2017 - 2020 Toyota 86. Features: These GrimmSpeed Dual Port Gaskets from the exhaust manifold to the head are made of premium multi - layer stainless steel. They are 22% thicker than OEM gaskets, ensuring an excellent exhaust manifold seal. After testing countless aftermarket gaskets, GrimmSpeed found that multi - layer steel OEM - style gaskets work the best. Many exhaust gaskets, even if multi - layer, aren't fully made of stainless steel, which can lead to leaks. But these gaskets have a 304 stainless steel fire ring and are made of premium multi - layer steel. They cross - reference with Subaru part #14038AA000 and are sold as a pair. They are durable and offer great value for money.

Using these GrimmSpeed gaskets is straightforward. First, make sure your engine is cool before starting any work. Remove the old gaskets carefully from the exhaust manifold to the head area. Clean the surfaces where the gaskets will be installed to ensure a good seal. Place the new gaskets in position, making sure they are correctly aligned. Then, reinstall the exhaust manifold. As for maintenance, these gaskets are quite durable. But it's a good idea to check them periodically for any signs of wear or leaks. If you notice any issues, it might be time to replace them. And remember, keep them clean to extend their lifespan.
