A set of 8 replacement fuel injectors for the 5.7L HEMI V8, rated to flow more fuel than the stock injectors. Bigger injectors matter once an engine is modified (bigger cam, forced induction, E85) and needs more fuel than stock injectors can deliver. On an otherwise-stock truck this does nothing by itself and needs a tune to run right.
why this one — AmericanTrucks has it in stock at a clear price with a real product page, and DeatschWerks publishes an exact flow spec (1500cc/min) rather than a vague power claim. Only makes sense paired with a tune.
DeatschWerks sells this by flow rate only (1500cc/min per injector). No horsepower gain figure is published by DeatschWerks for this set.
Oversized injectors need a matching tune to run correctly - installing without a tune can cause a rough idle, poor drivability, or engine damage. May affect powertrain warranty.
