Royal Enfield Ignition Coil with Plug Cap & HT Lead (Waterproof) – Bullet 500 / Bullet Trials 500 (Euro 4) – RAC00154/A

If your Royal Enfield is showing hard starting, misfire under load, weak pickup, or intermittent spark, a tired ignition coil or cracked plug cap/HT lead is one of the most common root causes—especially on older EFI-era Bullets. The Royal Enfield genuine ignition coil kit RAC00154/A comes as a complete unit with coil + attached HT lead + plug cap, designed to deliver consistent high-voltage output to the spark plug and resist moisture ingress thanks to its waterproof configuration. 

Unlike generic aftermarket coils (which often have wrong resistance values, poor insulation, or non-matching connectors), this is the OEM-spec part intended for the models listed in the verified compatibility table below. Correct coil performance improves cold starts, stabilizes idle, reduces random cut-outs, and prevents repeat plug fouling caused by weak spark.

This listing is built to reduce returns: we only publish fitment that is verified through official fiche-style assignment sources. If your bike is not listed below, do not order until you confirm by VIN/microfiche or you message us with your chassis number.

FAQs 

1) Will this fit my Classic 350 / Bullet 350 / Thunderbird / Bullet X?
Please check part number before purchase.

2) Symptoms of a bad ignition coil/plug cap?
Hard starting, misfire at mid/high throttle, jerks under load, weak pickup, backfiring, and spark loss after the bike heats up are common coil/cap/lead failure signs.

3) Is this coil “with plug cap & wire” or only the coil body?
This part is listed as “IGNITION COIL WITH CAP CORD WATER PROOF”—i.e., coil with cap/cord (HT lead) included. 

4) Installation notes—anything to check before ordering?
Match: (a) your bike’s exact model/variant, (b) connector type, and (c) mounting orientation. If you share your VIN , we can help confirm.
