Neoprene 2-ply Air Duct Hose, 300F, Black Only. Our 2-ply Neoprene Air Duct Hose is an excellent choice for engine air intakes (leading to the airbox, or between the airbox and the throttle body). The -65° F to 300° F temperature range is high enough for most racing engine compartments (as long as you keep it away from hot exhaust systems).
