Using the COBB Delrin Oil Cap is easy. First, locate your Subaru's oil cap on the engine. Remove the old oil cap and replace it with the new COBB Delrin Oil Cap. Make sure to use the included shims for correct orientation. The new OEM seal will ensure a proper fit. When it comes to maintenance, just wipe the cap with a clean cloth regularly to keep it looking good. There aren't many special precautions, but always make sure the engine is cool before you remove or install the oil cap to avoid any risk of burns.
