Replacement injector for TRX420 models

This fuel injector fits Honda TRX420 FE FM TE FPE FPM Rancher models from 2007 to 2013. It matches the OE number 16450-HP5-603 and serves as a direct replacement for a worn or failed original unit. No modification is required during installation.

Cold-start reliability and flow matching

The injector is built from metal and plastic for long service life. It delivers the correct internal coil resistance and fuel flow rate to match OEM specifications, enabling fast start-up in cold environments. It runs out of utility if the OE number or model year falls outside the listed fitment.

Simple swap with basic tools

The part installs by removing the fuel rail bolts, disconnecting the electrical plugs, and pressing the new injector into place. The process needs a cool engine, a disconnected battery, and a check for leaks before and after starting. It frees the owner from injector-related starting issues without requiring ECU programming.

Questions about this item

Will this 16450-HP5-603 injector fit the original fuel rail on my 2007-2013 TRX420 Rancher without changing brackets or lines?

Yes, it is a direct replacement for the OE 16450-HP5-603 and requires no modification to the fuel rail, brackets or fuel lines on FE, FM, TE, FPE and FPM models from 2007 to 2013.

How can I verify the injector is working correctly after following the seven-step install?

After reconnecting the battery, turn the key to prime the pump and inspect every connection for fuel leaks; then start the engine and confirm smooth idle, crisp throttle response and no fault codes.

Does the box contain seals, clips or a wiring pigtail, or must I buy them separately?

The package includes only 1 x Fuel Injector; any O-rings, retaining clips or electrical connectors must be sourced separately or reused from the original unit.
