Platinum Racing Products - RB Twin Cam Pro Series Cooling Head drain

BLACK, SILVER, GOLD, PURPLE NORMALLY STOCKED - OTHER COLORS EXPECT 3-4 WEEKS LEAD TIME

Coupled with our latest release of our Pro Cas with -20 fitting we have now finalised a solution for a matching high flow rear head drain designed to maximise flow though the cylinder head.

Dry block with wet head type combinations would benefit extremely by allowing high volume cylinder head cooling.
