TracTuff RBB/ RBC Water Neck - V2
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 Originally made for a customer that wanted to reuse the PRB/ PRC style upper radiator hose in his RSX.
The billet K series water neck flange eliminates the bulky OEM piece with its huge heater core fitting and EGR provision. The flange is beautifully machined from 6061-T6 aluminum and incorporates a 1/2" NPT heater port.
The hardware kit includes four M8 socket head bolts, a 90° heater hose fitting, a 1/2" NPT plug and a pair of o-rings.
NOTE: Made to Order - Please allow 48-72 hrs. for this product to ship. The sensor port selection is optional. If you don't have/ need a sensor, don't select it. I only offer two threads: 1/8" NPT or 1/8" BSPT (Honda Single Prong Sensor).
