The Racer X Fabrication oil cap for the Subaru WRX / STI is a perfect aesthetic addition to any engine bay!! The oil cap is slightly smaller than the plastic OEM cap, which is perfect for anyone using an oil cooler adapter plate that has to be rotated for clearance by the OEM intake system. The oil cap is CNC machined from 6061-T6 aluminum and uses a viton o-ring for a perfect seal. The logo orientation is facing the front of vehicle when fully tightened, and the cap features hexagon spline for easy tightening. The oil cap comes standard in black anodize.
