$192.95

An inexpensive solution for all you K20A, K20A2, K20A3, K20Z1, and K24A1 engine owners looking to simplify your cooling system! Weather you have added a radiator that does not have a radiator cap bung... or you are in need of a higher fill point, we've got you covered. Dont settle for stuff that sits crooked!

The filler neck starts with a beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint as well as a 1/2" NPT water bypass port and machined o-ring groove for the OEM gasket. You can chose from a list of options to make the product as unique as your project;  including sensor ports for oem or aftermarket sensors, hose connection type and radiator cap bung type.

All billet parts are CNC machined from US milled 6061 aluminum. The domestic cap bung has a 1/8" NPT port and the import version has a 1/16" NPT for connection to an overflow. The domestic version uses any early model (late 70's Chevy C10 Pickup w/ 454) cap and the import version uses early model Honda (88'-91' Civic/ CRX and 90'-93' Integra) cap. 

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design that varies from this, please email us at sales@tractuff.com. If using AN lines we also recommend designing the upper radiator hose so that there is droop/ give so the engines movement and does not push/ pull on the radiator and fatigue any parts. The billet neck has a 1/2" NPT water bypass port and the hardware kit includes a hose fitting and a plug in the event you don't plan on connecting a bypass hose. The filler is welded so that it sits level when bolted to an engine leaned back 15° (exhaust side) for the traditional option and leaned forward 8° (intake side) for the gangster lean mount option. Depending on your fuel line routing, this may require you to make changes.
