• Model: CR6EIA-9
• Iridium centre electrode with V-groove to enhance spark performance and electrode life
• Recommended gap: 0.9 mm (0.Ø 35 in)
• Medium heat range for stable operation in typical outboard applications
• Nickel-plated shell for corrosion resistance
• Suitable for many small outboards and petrol marine engines
• Compatible with engines specifying NGK CR6EIA-9 or equivalent replacements - not branded as NGK unless specified on the product
• Check fitment for thread size, reach, hex size, seat type, resistor/terminal type and torque specification before installation

Confirm compatibility by comparing thread pitch, reach and heat range with your engine manufacturer’s recommendations. Iridium centre electrodes reduce wear and help maintain a consistent gap for improved starting, throttle response and longer service intervals compared with conventional nickel electrodes.
