NGK Iridium Spark Plug - CR9EIX
NGK Iridium Spark Plug - CR9EIX
This is the highest heat range in the range we stock, and it's matched to higher-revving, higher-performance engines that run hotter than a commuter single or twin. The Ninja ZX-6R and Z800 are four-cylinder engines and need four of these plugs for a complete service, while the Triumph Daytona 675, Street Triple and Tiger 800 range are three-cylinder engines and need three.
These aren't common bikes on Indian roads, so genuine, correctly-specced replacement parts can be harder to track down than they are for mainstream models.
Suitable For
- Kawasaki: Ninja ZX-6R Base, Ninja ZX-6R ABS Base, Z800 ABS Base
- Triumph: Daytona 675 Base, Daytona 675 R Base, Street Triple ABS Base, Street Triple R ABS Base, Tiger 800 XC/XCA/XCx/XR/XRT/XRx Base
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: How many of these plugs does my bike need?
A1: The Ninja ZX-6R and Z800 are four-cylinder engines and need four plugs, while the Triumph Daytona 675, Street Triple and Tiger 800 are three-cylinder engines and need three.
Q2: Why is this plug's heat range higher than the CR7EIX or CR8EIX?
A2: These are higher-revving, higher-performance engines that generate more combustion heat than a commuter engine, so a hotter-range plug clears deposits more effectively at those temperatures.
