IN-STOCK, NO LEADTIME!

Our Honda K-Series Ultra loom was designed to provide a solution for the compact and 'busy' engine compartments typically found along with these engines and their growing applications. Care was taken during the design process to ensure all portions of the loom were routed away from all heat sources. The loom's main body is ran down the passenger side frame rail and along the front of the engine - allowing for large frame turbochargers and/or fender exit exhausts without any cause for concern.

This package consists of pre-configured engine and chassis looms based on our tried and true solution for this platform that has been relied on by some of the most successful programs since 2013 - many of which are still running to this day.

Our harnesses are proudly made in the USA at our facility in Boonton, NJ and are constructed with the same expertise, technique, and standards as found in the top tiers of motorsport we have both product and services in for over a decade. All transitions are fully sealed, the harness is concentrically twisted for maximum flexibility and strain relief, and all connections are terminated with professional grade tooling.

A spiral bound workbook is included with complete documentation including ECU channel assignments, wire colors, destinations, and connection details.

Cirris Hipot testing is available upon request via our in-house CH2 tester and carries an additional cost if required. Please contact us for more information.
