The Spectre 3-inch air duct hose kit provides 28 inches of flexible, memory-fit ducting and two threaded PVC couplers to route cooler air from an airbox inlet, plenum, intake tube or mounting plate into your engine. Multiple sections can be threaded together for longer runs, and the hose’s easy-bending memory-flex helps retain position. Replacement coupler PN 87411 is available; use clamps for a secure seal.
