The COBB Delrin Oil Cap is a must - have for your Subaru. It fits a wide range of models including the 2002 - 2022 Subaru WRX, 2004 - 2021 Subaru STI, 2004 - 2018 Forester XT, 2005 - 2012 Legacy GT, and 2005 - 2009 Outback XT. Unlike metal oil caps, this one is made of pure medical - grade black Delrin, which won't absorb heat. So you don't have to worry about burning your fingers when adding oil. It features a laser - etched COBB logo, a black finish, and comes with a new OEM seal and shims for perfect orientation. The fluted edge design offers great grip. Installation is easy, and an installation guide is included.


Using the COBB Delrin Oil Cap is a breeze. First, locate the oil cap on your Subaru. Remove the old oil cap and clean the area around it. Then, place the new COBB Delrin Oil Cap on the opening. Make sure to use the included shims for proper orientation. Simply twist the cap clockwise until it's snug. For maintenance, you can use a mild cleaner to wipe the cap. Avoid using abrasive materials that could scratch the finish. When not in use, keep it in a dry place. Also, check the seal regularly to ensure a tight fit. If you notice any signs of wear, replace the seal promptly.
