Fitment Information: These gaskets fit 2002 - 2021 Subaru WRX, 2004 - 2021 Subaru STI, 2013 - 2020 Subaru BRZ, 2005 - 2009 Subaru Legacy GT, 2005 - 2009 Subaru Outback XT, 2004 - 2013 Subaru Forester XT, 2013 - 2016 Scion FR - S, and 2017 - 2020 Toyota 86. Features: The GrimmSpeed Dual Port gaskets between the head and exhaust manifold are made of premium multi - layer stainless steel. They're 22% thicker than OEM gaskets, providing an excellent exhaust manifold seal. After testing countless aftermarket gaskets, we found that multi - layer steel OEM - style gaskets work best. Many exhaust gaskets, even if multi - layer, aren't fully stainless steel, causing leaks. But GrimmSpeed offers premium multi - layer steel gaskets with 304 stainless steel fire - rings at an affordable price. Key features include their location between the head and exhaust manifold, durable multi - layer steel build, 22% greater thickness than OEM, 304 stainless steel fire ring, cross - reference with Subaru part #14038AA000, and they're sold as a pair.

Using these GrimmSpeed gaskets is easy. First, make sure your engine is completely cooled down. Then, remove the old gaskets carefully from the exhaust manifold and the head. Clean the surfaces thoroughly to ensure there's no debris or old gasket material left. Place the new gaskets in position. Make sure they fit snugly and align properly. When reinstalling the exhaust manifold, tighten the bolts evenly to avoid uneven pressure. As for maintenance, there's not much you need to do. Just keep an eye on them during regular engine check - ups. If you notice any signs of leakage or damage, it's time to replace them. Also, try to keep the engine in good condition to extend the life of these gaskets.
