The URD 7th Injector Kit Kit for the Toyota 3.4 V6 equipped with the NEW Magnuson TVS-1320 Supercharger.  NOT FOR THE OLDER TRD/MAGNUSON MP62 Supercharger.

  1. Increase Torque
  2. Increase Horsepower
  3. Eliminate potentially engine damaging High RPM Lean Out
  4. In most cases, eliminate High Gear / Low RPM Ping
  5. Provides the needed part throttle boost enrichment

We are often asked why we offer 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.

Another great benefit of spray the fuel through the rotor assembly is that will evaporate and take a good bit of heat out of the air being compressed by the rotor assembly.  This can increase effective boost and cool the compressed air resulting in increased performance. This feature is very beneficial when running higher boost URD SuperGrip Supercharger Pulleys.

URD recommends the URD 7th Injector kit for all 5VZ-FE applications that have the MAGNUSON TVS 1320 Supercharger installed.  The only vehicles that we recommend our original 6 injector fuel kit for are the older ones that are equipped with an Exhaust Gas Re-circulation (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.

URD’s customers have long enjoyed benefits from URD’s Fuel Upgrade Kits including: increased horsepower & torque, smoothness, end user tunability, the elimination of high RPM lean out, and in most cases the elimination of high gear/low RPM ping. 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.  THIS KIT WILL NOT FIT ON TRUCKS WITH AN EGR SYSTEM
