This is a brand new aftermarket external ignition coil, built as a direct replacement for the original unit on the Honda TRX 420 Rancher in its TRX420FE, TRX420FM, TRX420TE and TRX420TM forms. The ignition coil converts the low voltage switching pulse into the high voltage the spark plug needs, and it is one of the components that degrades quietly with heat and vibration rather than failing outright, which is why a tired coil often shows up first as hard hot starting.
Fitting is plug-and-play and direct fit. The body measures 72 mm long, 51 mm wide and 38 mm high, with 63 mm between the centres of the two fixation holes, so it lands in the original mounting position without adapters. The wire lead is 500 mm long and the spark plug cap is supplied with the coil, so unlike many replacement coils you do not need to transfer anything over from the old unit. Every coil is tested before it is shipped.

Frequently Asked Questions
Will this fit without modifying my wiring?
Yes. It is a direct fit with 63 mm between the fixation hole centres and a 500 mm lead, so it mounts in the original position and connects to the existing harness. No cutting, splicing or drilling is required.
What is included in the box?
You receive the external ignition coil complete with its spark plug cap. Every unit is tested before it is shipped, so nothing needs to be transferred from your original coil.
How do I know my old ignition coil has failed?
The usual pattern is hard starting when hot, a misfire that worsens under load, and cutting out that clears once the engine has cooled down. A weak or intermittent spark at the plug points the same way. Before condemning the coil, check the plug itself, the cap, and the condition of the lead where it enters the coil body.
Does this suit both the electric shift and the manual Rancher?
Yes. The fitment covers TRX420FE and TRX420TE electric shift models as well as TRX420FM and TRX420TM manual shift models over the 2007-2014 span. Confirm the OEM number 30510-HP5-601 on your original unit if you are unsure.
