Technical Specifications
Specifications are populated as verified. Fields marked Verification in progress will be updated when independently confirmed.
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.
