Expansion Tank- This unit replaces the factory plastic one that is known to fail. The Fill neck used in the construction is machined from Billet 6061-t6 aluminum which will yield a very long life span and reliable seal. We top that off with a Billet aluminum cap that is black anodized.

Overflow- An internal Over-flow tank is incorporated into the Catch can for heavy track and racing use when required by the sanctioning body.

Catch Can- Available in -6 (factory pcv hose size), -8, and -10 for higher output applications! The catch can portion is one of the largest available for the GT-R and features an internal Double Baffle for superior oil separation. By combining the cooling system and the catch can into one simple unit, we take advantage of the extra heat that helps evaporate the water in the system and insures that a cleaner gas is being recirculated to the intakes for added knock protection.

**Each Catch can comes with the Fill Cap, and the Brass barb fittings for the factory coolant hoses. The "Make it a Kit" option will add the 4 an hose ends and 8' of black braided hose.
