TRD supercharger

Toyota Racing Development offered a TRD supercharger for the FJ Cruiser and Tacoma equipped with 4.0-liter V6 engine, available through Toyota dealerships. The supercharger increases the Tacoma's power output to 304 hp (227 kW) from the original 236 hp (176 kW), and the torque output to 334 lb·ft (453 N·m) and is now out of production.^[37]
This all-new TRD supercharger is compatible on all 2005 through 2015 model year Toyota Tacoma trucks, and 2007 through 2009 model year FJ Cruiser SUV.^[38] This supercharger system features Eaton roots-type rotating components in a one-piece integral manifold, iridium spark plugs, and a five-rib serpentine drive belt system. It produces about 6 psi (0.41 atm; 41,000 Pa) of boost pressure.
The supercharger, when installed by an authorized Scion or Toyota dealer, has the same warranty as powertrain, five years or 60,000 miles (97,000 km), or the balance of the new car warranty, whichever is greater. When not installed by an authorized dealer, the supercharger is covered by a 12-month, 12,000-mile (19,000 km) parts-only warranty. The manufacturer's suggested retail price of the TRD supercharger is $4,500, not including installation.
The TRD supercharger program is being discontinued for all vehicles, including Tacoma, as of June 2015.^[39]
