TracTuff PRB/ PRC Filler Neck - V1

$212.95

An inexpensive solution for all you K20A, K20A2, K20A3, K20Z1, and K24A1 cylinder head owners looking to simplify your cooling system! Whether you have added a radiator that does not have a radiator cap bung or you are just in need of a higher fill point to aid in burping the sometimes troublesome k series cooling system, we've got you covered.

The filler neck starts with a beautifully machined billet 6061-T6 flange which incorporates the largest passage possible within the OEM gaskets footprint, a -8 ORB water bypass port, and a machined o-ring groove for the OEM gasket. You can choose to add a sensor port directly to the top of the flange (near the logo) or the side of the flange (under the outlet). The outlet itself can be configured for standard hose (1.25" OD) or -16 male flare.

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. The cap bung has a 1/16" NPT port for connection to an overflow and uses early model Honda radiator caps; such as an 88'-91' Civic/ CRX or 90'-93' Integra. If you are using AN lines, I 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 hardware kit includes a -8 ORB to 11/16" water bypass hose fitting, a stainless hose clamp, two stainless M6 socket head bolts, and a Genuine Honda gasket. The filler 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 Hasport Gangster Lean mount option. 

DISCLAIMER: Depending on your fuel line routing... you may be required to make changes. You may also want to take a look at the V2 Filler Neck for additional flexibility and options.
