Race Spec Honda K-Series Ultra Loom Package

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. Care was taken during the design process to ensure all portions of the loom were routed away from all heat sources - a common issue with this application. Depending on the chassis, the loom's main body is typically ran down the passenger side frame rail and along the front of the engine - allowing for large frame turbos and fender exit exhausts without any cause for concern. Additionally, we have two other layouts for this engine to suit your project.
