NGK CPR8EAIX-9 Iridium IX Spark Plug

NGK CPR8EAIX-9 Iridium IX Spark Plug | Universal Fitment

The NGK CPR8EAIX-9 is a fine-wire iridium spark plug engineered for motorcycles and scooters that specify the CPR8EAIX-9 plug code. It replaces the OEM spark plug on a wide range of Indian-market bikes across Hero, Honda, Bajaj, TVS, Yamaha, and Aprilia platforms - with no modification required.

If your service manual, owner's manual, or mechanic specifies CPR8EAIX-9 as the correct plug code, this is the exact component.

Technical Specifications

Why Iridium IX Over Standard Nickel

The iridium centre electrode runs a 0.6 mm fine-wire tip — far narrower than a conventional nickel plug. This concentrated spark focus means:

• Cleaner ignition of the air-fuel mixture on every combustion cycle
• More stable idle and throttle response
• Longer service interval compared to nickel plugs
• Consistent performance across varying fuel quality and riding conditions

The CPR8EAIX-9 is an OEM-grade replacement, not a modification. It does not alter engine tuning, fuelling, or timing — it simply performs the ignition function more reliably and for longer.
