Fuel Injectors for 6.9/7.3 IDI Engines

Each set is meticulously pressure-matched to within 50 psi and features remanufactured stock OEM nozzles for reliable performance. These injectors are equipped with durable Viton o-rings and copper washers, ensuring a secure seal and optimal function. They are ideally suited for use with new injection pumps that have an output of less than 100cc. For IDI engines operating with more than 100cc, Classic Diesel Design recommends their stage one injectors for enhanced exhaust gas temperature management, improved mileage, and overall performance. Classic Diesel Design stands behind these injectors with an industry-leading 5-year unlimited mileage warranty. The product requires a core exchange, with a $100 refundable core charge. Customers can opt to send their cores upfront for immediate shipment of the new injectors, pending availability. Alternatively, new injectors can be shipped upon reception and inspection of the cores.
