  • TracTuff RBB/ RBC Water Neck Assembly - V2

    $169.95

    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 Originally made for a customer that wanted to reuse the PRB/ PRC style upper radiator hose in his RSX.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 RBB/ RBC water neck assembly starts with a beautifully machined 6061-T6 aluminum flange that incorporates the largest port possible within the OEM gaskets footprint, a welded 1.25" tube that mimics the OEM PRB/ PRC outlet position, and a 1/2" NPT heater port. The hardware includes four M8 stainless steel socket head bolts, a 90° water bypass hose fitting, a plug in the event you don't plan on connecting a bypass hose, and as of 8/1/20 a Genuine Honda gasket. 


    NOTE: Made to Order - Ships Same Day IF Ordered before 11 am PST - If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. The tube is welded so that it sits level when bolted to an engine leaned back 15° (OEM position) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option.
