NGK Iridium Spark Plug - CR7EIX
NGK Iridium Spark Plug - CR7EIX
The CR7EIX is one of NGK's more widely-fitted iridium plugs, which is why it turns up on bikes as different as a Royal Enfield Himalayan and a TVS Apache RTR. The "7" in the code is the heat range, a mid-range rating that suits engines that see a mix of city and highway use rather than pure track riding, and it's this heat range, not the bike's brand, that actually decides fitment.
Like every plug in NGK's iridium range, the electrode tip is ground to 0.6mm, finer than a standard copper plug, which is what gives it the smoother idling and slightly crisper throttle response riders notice after switching over.
Suitable For
- Royal Enfield: Himalayan 411cc (BS-3 and BS-4), Interceptor Twin 650cc, Continental GT Twin 650cc
- TVS: Apache RTR 160, RTR 180, RTR 180 ABS, Centra, Victor GLX 125, Victor Edge 125, Fiero (all models), Flame
Compatible with both BS-4 and BS-6 vehicles, including fuel injection and oxygen sensor setups.
NGK Iridium spark plugs use very precious Iridium metal at the tip of center electrode of diameter 0.6mm and has a thermo-edge design for central electrode. These features give anti carbon fouling performance, smoothest running, and excellent acceleration with increased mileage and are used and appreciated by most racing bikes and cars all over the world.

FAQs
Q1: Is this the right plug for a BS-6 Himalayan?
A1: Yes, the CR7EIX is rated for BS-6 fuel systems, fuel injection, and oxygen sensor compatibility, alongside the older BS-4 Himalayan setups.
Q2: My Apache RTR 160 came with a copper plug. Will this fit without any other changes?
A2: Yes, it's a direct fitment for the RTR 160 and 180, no other changes needed. You're simply swapping the stock copper plug for the iridium equivalent in the same heat range.
