Visual Identification

Verified visual identification characteristics for the 805225A1 will be added once confirmed. Do not rely on appearance alone to confirm fitment — always verify by OEM part number, engine model and serial range.

Compare the injector removed from your engine with the identification views shown here. Visual similarity alone does not establish fitment. Verify the OEM part number, engine application, and serial-number range before ordering.

What's Included

Package contents will be confirmed once the replacement product is sourced and verified.

Your Replacement May Look Different

The original 805225A1 injector used a metal-bodied Keihin design. Modern replacement injectors may use a substantially different composite-body design while being engineered for the same application.

Do not determine compatibility from body appearance alone. Verify the part number, engine application, serial-number range and applicable specifications before ordering or installation.

Replacement injectors may differ substantially in appearance from the original OEM-style injector. Verify compatibility by part number, engine application, serial-number range, and applicable specifications before ordering or installation.

How to Verify Fitment

Step 1.Locate your engine data plate and confirm the exact engine model designation (e.g. 454 MAG EFI, 454 MAG MPI, 7.4L MPI MIE, 7.4LX MPI).
Step 2.Record your engine serial number and confirm it falls within one of the verified serial ranges listed in the Engine Applications table above.
Step 3.Compare your existing OEM part number — from the original injector body or your service manual — to the OEM reference 805225A1 on this page.
Step 4.If you are uncertain about fitment, contact us before ordering. We would rather help you confirm the correct part than process a return.
