4JH1+50

CORE CHARGE WILL BE REFUNDED ONCE CORES ARE SENT BACK

Our in-house designed and built +50 injectors for the 4JH1 engine with the VP44 pump found in some of the TF and RA Rodeo’s and in the NKR Isuzu truck. We are currently the only shop in the world offering oversize injectors for this engine. We don’t sell the nozzles alone for these injectors as lift and pressures are modified inside the injector upon assembly. These injectors are like our +30’s but offer even more power gains through more fuel flow. As proven time and time again on our dyno and others around the country, simply fitting these injectors and adding approximately 6 – 8 psi boost pressure will increase power and torque by approximately 50%. It’s that easy!! Don’t forget to add 4 injectors to your basket for a full set. These injectors are sold on an exchange basis and a $50 core charge is already included in the price; this will be refunded upon the return of your old injectors. Or you can send your injectors to us to be reconditioned.
