A Nitemare Performance Exclusive:
Billet Pro Series Water Neck ($65)


Is your factory-original thermostat housing pitted from corrosion through the years?

Or worse: does it leak because the hose or base won't seal properly without a messy coating of RTV?

Don't replace it with a flimsy, foreign aftermarket housing. Instead, bolt on one of Nitemare Performance's all-new, custom-engineered Pro Water Necks!

Nitemare Performance's Pro Water Neck is a CNC-milled, welded two-piece, billet aluminum design with an extra-thick base and flange for a leak-free set up.

Engineered and built in the USA, our Pro Water Neck doesn't just look good -- it features a high-flow bore to eliminate coolant restrictions and minimize any cavitation within your Pontiac's cooling system.

The finishing touch is -- quite literally -- the finishing touch: a clear anodized coating to protect the Pro Water Neck from corrosion or damage.

Works great with our ...
