TracTuff RBB/ RBC Water Neck - V2

$172.95

Essentially an OEM replacement upper water neck for the K24A, K24A2, K24A4, K24A8, and K20Z3 when going into a chassis that originally came with a K20A, K20A2, K20A3, K20Z1, and K24A1. Originally made for a customer who wanted to reuse the PRB/ PRC style upper radiator hose in his RSX.

The fabricated K Series water neck replaces the bulky OEM piece with its huge heater core fitting and EGR platform. The water neck starts with a CNC machined 6061-T6 aluminum flange and has a mandrel-bent section of 1.25" tube welded to it that mimics the OEM outlet position. The flange incorporates a 1/2" NPT heater port that can also be used as an outlet if you are not running in-cabin heat. 

The hardware kit includes four M8 socket head bolts, a 90° heater hose fitting, a heater port plug, an EGR Passage Plug, and a pair of o-rings. 

NOTE: Made to Order - Please allow 2-3 Business Days for this product to be made and ship - If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. The accessory port option was originally offered for those looking for a spot to add the factory single-prong sensor (shown), but can also be used to retain the IACV heater loop if you can find the correct fitting. The accessory port selection is optional; I only offer  1/8" NPT or 1/8" BSPT (Honda Single Prong Sensor). The port is angled as shown.
