TracTuff P72 Billet Water Neck w/ Swirl Tank

TracTuff P72 Billet Water Neck w/ Swirl Tank

$299.95

Okay B18C1 engine owners... this is the pennical of our water neck offerings! The proven swirl tank.

It all starts with our beautifully machined flange that incorporates a 3D tapered entry port for a seamless transition to the tubing that is routed to the tank. The backside of the flange has an o-ring grove for a positive seal without the hassle of Hondabond. The tank placement clears the distributor, VTEC solenoid, and the outlet still exits similarly to the original location; customers have actually reported that a trimmed GSR upper hose still works! 

1. Billet water neck with bead rolled 1-1/4" aluminum tube so you can attach your OEM rubber/ silicone hose - Not Shown

2. Billet water neck with 1-3/8" aluminum tube for a seamless transition to our -16 male bung - Shown

All billet parts are CNC machined from US milled 6061 aluminum. The radiator cap bung uses the larger domestic style cap for the largest opening and huge selection of cap offerings. 

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. If using AN lines we also recommend designing the upper radiator hose so that there is droop/ give so the engines movement and does not push/ pull on the radiator and fatigue any parts. The tank is welded so that it sits level when bolted to an engine with a 5.5° lean forward (exhaust side).
