2004 Tacoma 4wd Xtra Cab, Manual Transmission - 7th Injector Kit

These kits are designed to upgrade later application 3.4L V6 superchargers for maximum power. The kits include a 7^th fuel injector with hardware and fuel lines along with a plug-in piggyback ECU. The extra injector delivers the additional fuel required for maximum output, and the piggyback ECU modifies the fuel delivery and ignition timing to optimize performance

For the easiest, most dramatic and most reliable boost in horsepower and torque, Toyota Racing Development offers several superchargers designed and developed for popular Toyota cars, trucks, SUVs and Scion cars. TRD superchargers are belt driven from the crank, delivering more torque and horsepower from idle to redline. Unlike exhaust-driven turbochargers, TRD Superchargers give you immediate throttle response. You get the power and torque of a larger displacement engine when you need it and the lighter weight and greater efficiency of a smaller engine when you don't. TRD Superchargers deliver the extra torque you need for towing, passing and carrying heavy loads. Because they pack more air into every cylinder stroke, they are especially effective at higher altitudes.
