TracTuff PRB/ PRC Rear Wheel Drive K Swap Remote Filler Neck

Description

Normally, the water neck on a K is right in front of the radiator and pretty much equal in height… and even then, the K is notorious for being a bitch to bleed!

Now, rotate the motor 90°, tuck the back of the cylinder head into the firewall or under a cowl, and you have limited access to the highest point on the motor. The design of the upper hose usually results in the formation of an air pocket as it dives down under the intake manifold. Originally designed for a K20A swapped RX8, the filler tube wraps around the intake manifold and turns upward over the runners, significantly reducing the headache of adding fluid and bleeding the system at its highest point.

NOTE: The radiator cap bung has a 1/16″ NPT port for connection to an overflow and uses early model Honda radiator caps, such as an 88′-91′ Civic/ CRX or 90′-93′ Integra. The sensor port selection is optional; if you don’t have/ need a sensor, don’t select it.

The billet flange used in this product does not have a water bypass port, so it will need to be added to the outlet tube if it’s to be retained. You can choose either a 5/8″ hose barb or a -10 male flare. Use the Thermostat Port Adapter to complete the -10 connection. The hardware kit includes two stainless M6 socket head bolts and a Genuine Honda gasket. The filler tube is welded so that it sits level when bolted to an engine leaned back 15° (OEM position).
