This machined Delrin oil cap from Cobb Tuning will keep oil in your engine with a bit of style. The Delrin material doesn't retain heat, and it looks very nice.
CNC'd with the Cobb logo subtly machined in the surface and helpful grippy indentations around the edge.
Black in color. Includes rubber O-ring, plus shims so you can adjust the orientation so the logo looks right when it's tight.
Fits all 2002+ Subaru WRX, 2004+ STI, 2005+ Legacy GT/Outback XT, and 2004+ Forester XT. Most other late-model Subarus, too.
