These are HOLDERS stage 6 competition injector. They displace 350cc of fuel and are all a single shot style hybrid injector. The hybrid injectors allow you to deliver more fuel with less high pressure oil. You will need custom tuning for these to run to their full potential. We recommend running a 100-400% nozzle with these depending on your goals. The smaller nozzle will help with fuel atomization and controlling EGT’s for towing while the larger nozzle will be better for top end power. These will require fuel system and high pressure oil upgrades. HOLDERS always recommends you check your fuel pressure after installation and ensure it never drops below 45 psi under load.
***If sending in 99-03 year model injector cores there will be an additional $150 charge for converting them to single shot style injectors***
This is not an exchange program. This is a rebuild service that you have to send your injectors in to be rebuilt and you get back the same injectors you sent in to be rebuilt. So you know the mileage and history of the injectors. If you are sending in AD or AE code injectors for a performance upgrade there will be an additional $150 charge for converting them to single shot injectors. Once HOLDERS receives these injectors they get cleaned and inspected. Then HOLDERS replaces the plunger and barrel assembly, nozzle, nozzle lift spring, poppet spring, refinish all sealing surfaces and install all new seals and gaskets. After completion these are bench tested on our Hartridge HA-230 flow bench to ensure flow rates and functionality. These include a 12 month warranty. If your injectors cannot be rebuilt with this service we will contact you and give you and proceed from there. .
