TracTuff RBB/ RBC Water Neck - V1
Essentially an OEM replacement upper water neck for the K24A, K24A2, K24A4, K24A8, and K20Z3.
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 1.25" angled tube that mimics the OEM outlet position is welded to the flange. A 1/2" NPT heater port is standard regardless if you plan on using it.
NOTE: Made to Order - Please allow 48-72 hrs. for this product to ship - If you are interested in a specific design that varies from this, please email us at firstname.lastname@example.org. 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 mounts.
The hardware includes four M8 stainless steel socket head bolts, a 90° heater hose fitting, a plug and a Genuine Honda gasket.
1/8" NPT Accessory Bung option shown. Originally offered for those looking to retain the IACV heater loop. It is a FEED and should not be used as a return.
