A steel heatshield, finished in black powdercoat isolates the filter from ambient underhood heat to supply the engine with cooler denser air. The 77 Series polished intake tube (
) is coupled to the OE components with reinforced silicone hose to absorb engine vibrations. Stainless-steel hose clamps secure parts to one another and black powdercoated steel brackets add additional support.
K&N's High Flow Replacement filter (
) provides optimal air flow and is backed by K&N's Famous Million Mile Warranty.
