The URD 7th Injector Kit Kit for the Toyota 3.4 V6 equipped with the TRD Supercharger: ( NON EGR APPLICATIONS)

  1. Increase Torque
  2. Increase Horsepower
  3. Eliminate High RPM Lean Out
  4. Eliminate High Gear / Low RPM Ping
  5. Provides the needed part throttle boost enrichment

We are often asked why there is two different fuel kits for the TRD Supercharge for the 5VZ. Our original product when we started URD was the Fuel Upgrade Kit that replaces all 6 injectors with larger ones. That is a great kit, but we found that using a simpler approach and using a single additional injector works better. The 7th injector kit has better altitude compensation, it is easier to install, and the pre-loaded start up program is good for 99% of the trucks out there and almost never needs any additional tuning by the end user.

Some other benefits come from shooting the fuel through the supercharger. The Eaton 3 lob rotor used by TRD is not the most efficient available. The fuel going through the rotor housing helps provides a better seal between the rotors and the housing and reducing the back flow problem with the 3 lob rotor design and reduces the heating of the compressed air by reducing the backflow. The fuel also removes some existing heat from evaporation of the fuel in the heated compressed air. This can increase effective boost and cool the compressed air resulting in increased performance. This feature is very beneficial when running higher boost pulley.

We recommend the URD 7th Injector kit for all 5VZ-FE applications that have the TRD Supercharger installed. The only vehicles that we recommend our original 6 injector fuel kit for are the older ones that are equiped with an Exhaust Gas Recirculation (EGR). The reason for this is that we mount the 7th injector into the EGR port on the supercharger. If that port is occupied with an EGR valve the URD 7th Injector Kit will not fit.

Customers have long enjoyed benefits from URD's six injector Fuel Upgrade Kit including: increased horsepower & torque, smoothness, end user tunability, the elimination of high RPM lean out, and the elimination of high gear/low RPM ping. These benefits are present in the newer kit too. Power gains are usually in the 30-40 hp range and sometimes higher depending on how lean your truck is currently running.

URD's 5VZ 7th Injector kit is fantastic for any truck running a higher boost pulley, or anyone who wants optimal truck performance.

Note: It is recommended that any EGR equipped trucks use URD's original Fuel Upgrade Kit.

When placing your order, please place your vehicle information in the comments box in the check out. We need to know what vehicle and year it is so we can include the correct vehicle specific installation guide.

Also please select which supercharger you have. The 1st Gen units were GRAY, and the current 2nd Gen units are BLACK. This info is needed because the fuel line is different for each supercharger.
