VG30DE(TT) / RB25DE(T) Billet Half-Moon Cam Plugs

Billet aluminum half-moon plugs replace the stock rubber plugs used in the cylinder heads under the VG30DE(TT) exhaust valve covers and both RB25DE(T) intake and exhaust valve covers. Aluminum will not shrink with exposure to heat and oil, and eliminates valve cover oil leaks in this area.

For final installation, apply a very small amount of RTV silicone to the area that touches the cylinder head pocket. Do not use the valve covers to press the half-moons into position – instead, use a block of wood with a small hammer to tap them into position.
