TracTuff H22 Filler Neck

$197.95

The P13 (H22A) cylinder head filler neck helps 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 cooling system. 

The filler neck starts with a beautifully machined 6061-T6 flange that incorporates an OEM o-ring grove for a positive seal without the hassle of Hondabond. The outlet can be configured to your needs, whether that be straight tube (shown) that essentially follows the OEM angle or a curved tube that produces a 90° outlet that points to the passenger fender and terminated for either 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. If you have questions related to the configuration or options... PLEASE visit the WHATS WHAT or FAQ page. 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 filler is welded so that it sits level when bolted to an engine with a 10.5° lean back (traditional) or 4.2° lean forward (QSD H2B).
