NGK Iridium Spark Plug - CR9EIX
Customer Product Reviews
Great product, very happy
Super fast delivery yet again from Sportsbikeshop. My bike was definitely overdue some new plugs and I thought I would give the iridium ones a try. The bike definitely starts easier from cold and the idle is much smoother. Hard to say if the iridium makes a difference though as the old plugs were that bad. After a price match they were an even better price too!
Looking for spark plugs and doing my research on the best spark plugs for my bike and of course Sports Bike Shop had it. Plenty in stock with a good delivery time, arrived with me bang on time. Well packaged and price matched! Very happy with purchase and service. I have done a lot of custom with Sports Bike Shop and will continue to do so!
A good spark makes the difference
Definitely improved starting. The engine sounds sweeter, and seems to have sharpened up the power to some extent. The main gain has been in fuel efficiency which has definitely improved by nearly 10 mpg..!However, like someone else in the reviews, I have also changed the air filter and I'm unsure about what has made the biggest difference. If your on a tight budget, then standard plugs will do, but if your aiming for excellence then the Iridium are necessary.
Bike starts well and goes well as per usual.
Fairly simple to fit, albeit some battered fingers/knuckles. Bike has had NGK iridium plugs fitted since new and always started well, so not sure how they would compare to standard plugs and that's if I was able to detect a difference.
Time will tell
I've rated these good on the basis that its very difficult to tell if they're actually any better than standard plugs. I did valve gaps, carb balancing, new air filter and oil change all at the same time. The bikes running great as a result but its hard to tell which of those has made it run smoother!
