Make your Duramax Fly. With the Allison 5 and 6 speed, the Duramax is already fun to drive. Why not add an addition kick with DDP Injectors. Unlike an electronic box, honed performance injectors are almost impossible for a factory technician to detect. With DDP’s Balance Honed injectors you can be confident that your warranty will not be compromised and you’ll have the extra pulling power to beat your friends up the mountain.
These 100 horsepower nozzles will give you 100hp at the wheels. You can use these in conjunction with an aftermarket electronic box or downloader without the worry of draining the fuel rail dry. Mileage will increase about 1-2 miles per gallon once the initial fun wears off and you start driving normally again.
These injectors are sold on an exchange basis. Up front you pay for the nozzles and a core charge and when you return your nozzles we will refund your core.
As always, this product is covered by our 1 year warranty. Please see our Policies section to read more.
Refundable core charge applies
