Subaru OEM Gasket and Seal Kit Subaru 2004-2006 STI | 10105AA5909X

Whenever doing head or short block engine work, it is very important to replace old or worn engine gaskets. Nobody wants to have to pull an engine because they forgot to replace an old seal or gasket. You can save time and money with a genuine Subaru OEM full gasket and seal kit for your STI. We strongly suggest this kit for any engine swaps, rebuilds, or upgrades. For build date specific kits, build dates can be found on the information plate located in your drivers side door jamb. IMPORTANT: valve cover gaskets are NOT included in this gasket kit. Gasket and seal kits differ slightly depending on model year and/or build date.
