Installation Advice

For the best engine performance we recommend replacing the complete set of injectors at the same time. New and worn injectors deliver fuel differently, and mixing them can cause uneven running. Please compare the part number on your old injector before ordering.

Warranty and Shipping

Every injector from InjectorHub comes with a 12-month warranty and fast worldwide shipping. Not sure it is the right part? Send us the code from your old injector or your engine serial number and we will confirm compatibility.
