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).

This hose is extremely flexible and pliable, but a bronze coated spring-steel wire support helix prevents it from collapsing. The fiberglass fabric cover and fiberglass cord are both impregnated and coated with neoprene rubber. A second layer of neoprene covers the inside of the hose to reduce turbulence. Black only.

Note: These ducts are manufactured in 12 foot nominal lengths but only measure 12 feet when stretched tightly. The actual lengths will generally measure several inches less than nominal.
