I'M SATISFIED OF THIS PRODUCT.
SO I NOTICED AROUND 5000 RPM ,THE ENGINE SEEMS LIKE TO HAVE BLOWS. AS IS AN RACING PLUG YOU HAVE TO MAINTAIN A CERTAIN POWER FOR AVOIDING BLOWS.UP 5000 RPM YOU HAVE GOOD SENSATIONS.
We use it for Initial Model VTR. In the winter, I could not afford to catch Chalk, but I feel that the stability has been improved remarkably! Since only two months have passed since I exchanged it, I am not sure about Cospa and exhaustion However, I receive the impression that it is comparable to that just after I replaced it for the moment. I like the extent that it will probably be Windshield IRIDIUM for the next exchange as well
I exchanged Plug because it exceeded 11000 km. Although it is an impression of about 500 km, The attachment of Axel at 1500-3000 rpm improved, and the high rotation also turned well I think. 5 speed 40 km is easier to run. Just 2000-3000 Partial I feel that the area became irritable, and it became difficult to maintain a little with. I want to increase the vibration... Because the heat value is not matched, the original Plug may be more comfortable for regular rotation. I am worrying about returning.. Looking at you..
It will be a good price if we arrange 4 pieces and there is no change that can be experienced in fuel consumption and running feeling so there is no visible return. (I do not know the invisible part. ) My car will soon be 20 years old so I bought it for something like an adult celebration. It is completely self-satisfying..
Originally it is an exchange from the Normal plug without deterioration, If you replace it from a deteriorated state, you may feel some change. The thing is not bad, I wish to judge again whether I try to ride the distance.
Used in cb400sf nc39. Since the Normal plug completely failed, this time I got excited and I tried it as an Iridium plugs. Fuel economy, Power feels up. We plan to use this plug when we also exchange next!
