Spectre's Chrome Intake Tube Elbow features triple chrome plated co-polymer ABS resin construction, which insulates the intake tract from heat. With a 3 inch outside diameter, a 45 degree center bend, and a smooth interior engineered to help deliver superior air flow, this product can be combined with other 3 inch intake tubes to create an intake for almost any vehicle. This elbow is not intended for use on turbo-charged or super-charged engines.
