Engine Gasket and Seal Kit

The Subaru OEM Gasket and Seal Kit (part number 10105AC180) is a vital component for anyone undertaking head or short block engine work on their Subaru STI. Designed for 2008-2021 Subaru STI models, this comprehensive kit ensures that you have the necessary seals and gaskets to complete a thorough engine rebuild, swap, or upgrade without the risk of leaks from old or worn parts. With over 160 individual gaskets and seals, this kit aims to provide virtually everything needed for a complete engine overhaul, including critical components like head gaskets, spark plug O-rings, and intake manifold gaskets. It is crucial to be aware that this kit specifically does *not* include valve cover gaskets. This detail is important for planning your engine rebuild to ensure you procure any additional necessary components separately. This kit is strongly recommended for any significant engine work to save time and money by preventing potential issues down the line. This overhaul gasket set is designed for the 6MT transmission Subaru STI models from 2008 through 2021. It supersedes previous part numbers, including 10105AB200.
