E3 Spark Plugs E3.38 Premium Powersports Spark Plug with DiamondFIRE Technology, 10mm, 0.750” Reach, Gasket Seat, For Honda, Suzuki, Yamaha, and Other High RPM Engines, Pack of 1

Amazing spark plugs. After easily installing they have been working great. They were luckily compatible with my 03 Vulcan 800b fitting into the holes perfectly. They have allowed me to have smooth rides and continue to fix up the bike.

Very interesting plug. I rebuilt an '01 KTM 400 EXC top to bottom. I usually run NGK CR8EIX plugs, and they work great. Since I re-jetted the bike, I figured I'd do a little experiment. I'm a maintenance freak, so my bike has always run at peak performance, but that requires constant maintenance, if you know anything about KTM's. Anyway, the plugs seem to work great. I haven't had the opportunity to switch back to compare with the NGK, but I will and will report back. Theoretically, the E3 plugs make sense. To be honest, before I run the NGK again, I'm going to buy another E3, because I'm not sure I'm even running the proper one for my KTM (even though I'm sure there would be little to no difference).

Fired my bike right up 👌🏿

I'm satisfied what else can I say good spark.

Well I bought this plug for my brand new RPS Cross-Country 300 EFI motorcycle. It fit and worked. But being a EFI, fuel injected, motor. You can't just throw parts out it. You will need to remap the the ECU unit for this plug to work grate. So it will have to wait for now. I have run E3 sparks plugs in all my motorcycle for a very long time. Will always run E3 Plugs.

Excelente producto

Muy bueno lo recomiendo

After waiting several days, I contacted E3 and was told yesterday that my package already shipped several days ago and that USPS was behind on their tracking information. I contacted USPS today and was told that the package arrived yesterday and shipped and the shipping label was created almost a week ago and that they've been waiting on the package in order to ship. I do not appreciate being lied to by E3. All I asked for was transparency and to know where my package was.

Habe für das Motorrad diese Zündkerzen bestellt, da Sie im Testvergleich von ProjectFarm gewonnen haben. Einen Stern Abzug gibt es für den vergleichsweise hohen Preis.

Goes well

excellente bougie, fit parfaitement sur raptor 700 2007. La qualitée et la performance y est.

Excellent plug great quality and amazingly quick shipping Will definitely buy again!!

Thought this was a good spark plug for my raptor with the big 3.. blew white smoke when it was in.. took it out after a cpl mins and put the stock plug back.
