Troubleshooting & FAQ
How do I confirm these injectors fit my engine?
Verify your engine model is a Suzuki DF60 or DF70 from the years 1998–2009. The most reliable method is to cross-reference the number stamped on your existing injectors with the OEM part number 15710-66D00 or the interchange part number CDH-166.
What are the signs of a faulty fuel injector?
Common symptoms include rough idling, engine misfires (especially at idle or low speeds), poor acceleration, increased fuel consumption, and difficulty starting the engine. A check engine light may also be triggered.
Why are these injectors sold as a flow-matched set?
Flow-matching ensures that each injector delivers the same amount of fuel. This "balanced" set provides a smoother-running engine, consistent power delivery across all cylinders, and optimal fuel efficiency. Replacing just one injector can lead to an imbalanced engine.
Are any special tools required for installation?
Standard mechanic's tools are generally sufficient. No highly specialized tools are typically needed for injector replacement on these Suzuki models, but a fuel pressure gauge is recommended for safely depressurizing the system.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
