Get your truck ready for the long haul with a more responsive engine, with the OTR Remanufactured Electronic Diesel Fuel Injector with Expertise Built In. This replacement component sprays a small amount of fuel directly into the combustion chamber, allowing engines to rapidly react while improving overall fuel efficiency. Thick exhaust, misfiring, and a stalling engine are all symptoms of an injector that may need replacement. FleetPride is your First Click in Heavy Duty.
