MAXFIREMaxFire A Super iridium plug
I already purchased it several times.
It is only the top of Windshield IRIDIUM? It feels like I will uphold a few horsepower comfortably.
Although it is expensive for four cylinders, single cylinder - I think that it will be worth a try if you have 2 cylinders.
It is recommended because it is cheap to buy with WEBIKE rather than purchasing Windshield IRIDIUM at a mass merchandise shop.
