The injector tips flow 30% more fuel then the factory 4JJ1 tips 
 
These are Torque Master injector tips made for the 4JJ1 and have been tested on many 4JJ1 3.0 with great results on factory or high performance Diesels 
 
These are a supply item only, we recommend a diesel shop to remove the old and put the new ones on for you or you may send us the injector and we can do it for you.
 
We also have a video on diesel smart youtube showing how to swap them at home or at a workshop
 
Nozzles will not be refunded if fitted to vehicle
