Injen Air Intake for the 1992 thru 1995 SC300 is a high-performance, Dyno-Proven system made of CNC mandrel bent 6061 T-6 aluminum alloy. Each intake is carefully engineered for a perfect fit and peak performance and then tested over and over again on a dynomometer for maximum Horsepower Gain and Torque. Many other intakes in the market use only a 3" diameter tube, which may cause friction between the battery and the intake system, dented hoods, and uneven air flow. Injen is capable of bending 2.5", 2.75", and 3" in diameter with many variations of the degree of bends . With the use of 1/4" thick 6061 T-6 aluminum and precise CNC machined brackets and adapters, you are guaranteed an exact fit every time. All components are manufactured in the USA and each kit comes complete with all necessary hardware and vibra-mounts. Backed by a Limited Lifetime Warranty... Shipping is $15
