The Nitrous Express GT500 nitrous plate system features a billet nitrous plate that bolts between the throttle body and intake making installation quick, easy and attractive. System includes billet aluminum and carbon fiber Lightning Series solenoids for the ultimate in power and durability. A direct-bolt on Fuel Rail Adapter is provided to simplify installation. System includes a TPS Wide Open Throttle Switch so the nitrous only activated at wide open throttle. The system includes jetting for 35/50/75/100/125/150/200/250 and 300WHP but you can expect larger power gains than normal due to the added power resulting from the cold air charge associated with Nitrous. System includes 15 ft. stainless braided nitrous line/master arming switch/relay/relay harness and all necessary hardware to complete the installation.
