About This Product
For V-Rod owners looking to squeeze every bit of performance out of their Revolution engine, these NGK Iridium IX spark plugs are the way to go. Designed to fit 2006 to 2017 V-Rod models, the KR8BI plug features an extremely fine iridium tip that offers superior anti-fouling and high ignitability. This translates to better throttle response and more consistent starts compared to standard or even platinum plugs. The high melting point of iridium is perfect for the high-temperature environment of the liquid-cooled V-Twin, ensuring a long lifespan and excellent fuel efficiency. It is a simple upgrade that makes a noticeable difference in how the bike runs.
Manufacturer part number: 4347.
