Yamaha FJ1200 supplied with SplitFire SF416C plugs.

I´m an expert Yamaha FJ 1200 owner with more than 300.000 kms riding only FJs an another 200.000 with other models. I don´t know if the bike has more power with the Splitfires (you would need a dyno to check it) but the bike feels so much sweeter, with less vibration, and start even better with the Splitfires.

BMW K75 supplied with SplitFire SF416C plugs

I bought a set for my BMW K75RT a few months back and I noticed an immediate improvement in power and response. It felt like the engine got a 20% boost. I feel like the bike has a bigger torque. It runs more balanced and more 'mature'. Almost as if the numbers of cylinders increased from 3 to 4. Even if I did not need more power out of the engine, I would still recomend as it feels more at ease and complete. Thank you for offering these plugs.

Honda CB600 Hornet supplied with SplitFire SF430B plugs

I used Splitfire spark plugs that were supplied by Bell Rock Racing in my Honda CB600 Hornet that I campaigned in the New-era HONDA HORNET SUPERCLUB championship.  This is a championship where no engine tuning is allowed so any product that can give you an edge is worth its weight in gold.

Even before the season had begun the bike was making good horsepower when put on the dyno with these plugs.  I had a very good season doing the complete championship and also track sessions once a month and only now am I going to replace the plugs but only as a matter of course.

What else could you ask for from a set of spark plugs and I must give this product 10/10.  I will be using these plugs for the next season both in my dry and wet bikes as these are items I can trust.

Splitfire says: The patented SplitFire "V" design on the side electrode is instrumental in helping to improve combustion efficiency. Because the flame kernel is not blocked by the side electrode as in other spark plugs, it can travel upward through the "v" notch into the combustion chamber . . . That's the SplitFire Performance "V" Advantage.
