Injector Kits

Injector Kits: matched flow for a fueling upgrade or a worn-out replacement

Injector kits deliver fuel into the cylinder at the pressure and volume your engine needs. When you turn up boost, swap a tune, or just wear out a set of tired injectors, matched flow rates keep the air-fuel ratio in check and the cylinders firing evenly. A set that flows too little starves the top end; too much and you drown low-load driveability. That is why these come as calibrated sets rather than single guessed parts, and why some listings here are repair fittings that fix the return-line side rather than the injector itself.

What ThreePiece stocks

This page shows 10 products across 6 brands: Radium Engineering, DDP, DeatschWerks, Fleece Performance, Bosch and BLOX Racing. Current in-stock pricing runs from $33 to $897 - that is the live range for what is on the shelf now, not a standing offer. Coverage spans diesel trucks and gas performance builds: the DDP 98.5-02 Cummins 5.9L 24V 100hp injector set and the DDP 75HP 24v set sit at the top end for Dodge Cummins trucks, while the DeatschWerks 550cc set for the 02-08 Mini Cooper S and the DeatschWerks 2200cc/min injector for the Yamaha Raptor 700 cover boosted and powersports applications.

Fitment data is present on 8 of these products, covering Ford, Dodge, Yamaha, Nissan and Mini across model years 1990 to 2024. Named vehicles include Dodge Cummins, Ford F250 through F650, the Yamaha Raptor 700, Nissan and the Mini Cooper S.

How to choose

Start with the job. If you are chasing more power on a diesel, the DDP Cummins sets are rated by added horsepower, so pick the step that matches your tune and turbo - the 100hp set asks more of the supporting fuel system than the 75HP. For a boosted gas build, injector flow in cc is what matters: a bigger number like the DeatschWerks 550cc or the Raptor's 2200cc/min supports more fuel demand but needs a tune to run right. Not every listing here is a full set - the Fleece Performance return-line repair fitting for 11-16 Powerstroke and its 2017-2024 counterpart fix a common leak point rather than replacing injectors, so check whether you need flow or a repair before ordering.

What else you need

Bigger injectors move more fuel than stock, so plan the supply side too. Look at Fuel Pumps to keep pressure up, and Fittings and Adapters to plumb the new hardware. If the injectors are coming out during a build, it is worth having Gasket Kits and Head Gaskets on hand. Browse the full Engine Components section for the rest of the parts a fueling job touches.

Fitment and ordering

Confirm year, make and model against each listing before you buy, and call 813-535-5801 if you need help matching a set to your build. All orders ship with free shipping, and Affirm and Katapult financing is available at checkout.
