These are what we would call our tow power injector. They displace 155cc of fuel and we usually pair these with either a stock or 30% injector nozzle. The smaller nozzle will help with towing maximum weight and keeping EGT’s down while the 30% nozzle will be better for more top end power. If your stock fuel system is healthy it will support these injectors. However, we always recommend you check your fuel pressure under load after installation. You want a very minimum of 45psi of fuel pressure at any time.
This is for a set of (8). This is not an exchange service. You send your injectors in to be rebuilt and receive back the same injectors that you sent in. You know the history and mileage of these injectors. These get all the major wear items replaced such as nozzles, nozzle lift spring, piston return spring, all seals and gaskets, spool valves polished and all sealing surfaces are refinished. These are all bench tested on our Hartridge HA-230 flow bench once completed to ensure all flow rates and functionality. These include a 6 month warranty.
If your injectors cannot be rebuilt with this service we will contact you for options and proceed from there. We always recommend especially on larger injectors to go with our Premium Remans. With all new parts in them they are naturally more reliable and will have better longevity.
