FAQs
Q1: Does this one plug cover both the 350cc and 500cc UCE models?
A1: Yes, it's listed across both displacements in Royal Enfield's UCE twin-spark range, as well as the Continental GT 535cc.
Q2: Do I need to buy a second plug alongside this one?
A2: Yes, UCE twin-spark engines fire two plugs per cylinder, so this needs a matching second plug for the other position. For the Thunderbird 350 specifically, that's the CPR7EAIX-9, and we sell both together as a set.
