YAMAHA JUPITER Z1
At the time of OEMPlug replacement, I made it to Windshield IRIDIUM at the same time.
Even with the Normal plug, it seems that Torque has just been upgraded if it is new, or just after cleaning, but it will return to original.
Iridium plugs it will last long... I feel it..
Plug is a cheap one in Parts and I am thinking that it is good to take a Manufacturer singing phrase as 500 yen does not change as I made it to Windshield IRIDIUM.
I exchanged BirdCity's Plug with Windshield IRIDIUM, but the exchange was Large strange at a narrow Space. Windshield IRIDIUM is good in Large change, but the installation space of the original chare is too narrow for disgusting. I thought that I could sell well even with a high Plug if I developed a Motorcycle that is easy to replace and a Plug that is easy to replace. I am expecting durability without being able to keep it.
I thought Windshield IRIDIUM did not have any big difference in size - - -
Engine's Torque feeling has increased and acceleration in the middle speed range has improved.
It seems that the highest speed is up slightly, and pulling it to 84 km / 87 km on the road where h was the limit / I got to come up to h.
Instead, I feel that fuel economy got a bit worse.
