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.

Fired my bike right up 👌🏿

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.

It gives me extra spark to get more complete combustion just as advertised. I notice a slight improvement in performance on my engine. This does seem like it fouls a bit quicker than normal and because of the shape it's hard to clean off to refresh the plug while you wait for a new one on order.

Bought my first E3.38 plug for my 2012 Kawasaki KLX250S, 250cc single cylinder stock engine. Wow! What a nice improvement! 1) perhaps 5% more visceral torque throughout the entire RPM range. 2) starting 60F cold engine - just choke and barely touch the starter! Immediate startup, no fuss, no 2nd or 3rd try. 3) gas mileage SHOULD be a bit better (not yet verified) because engine feels much stronger and more responsive across the range. This better response must be due to more uniform and stronger flame-front inside combustion chamber due to stronger, omnidirectional spark. This performance comparison was made against two different NGK "R" CR8E plugs, one with 4500 miles (factory stock), one brand new. The E3 plug's electrode technology seems to be a new lower cost version of the original TorqueMaster plugs from 1995, but with the same positive results. No need to gap an E3 plug, unlike a conventional plug. I will certainly try other E3 plugs for my other vehicles. I'm sold.

I tossed these in idk about 6 months ago into my 95 Vulcan VN800. I was having carb problems that was fouling out plugs but once I got these it they didn't foul out and stayed strong till I got my carb dialed in. Now this is my daily driver BTW. So now it oil change time and a once over. When I pulled the plugs I was amazed I barely had to clean them up and my bike has idled better since day one and has that snap back into my exhaust. Great plugs 200% recommend them well worth the money

The only reason why I gave this three stars, is not because the plug is bad, but rather, this does not fit my motorcycle at all, which is a 2023 Kawasaki Z900RS, where it has the exposed cap style, and while it threads right, it does not fit the boot. Don't get me wrong, I always stand by E3 premium plugs for most of my vehicles, especially the high compression ones, I'm just disappointed that after researching for a good amount of time, I ended up wasting about $40, and since I already opened up the package and actually inserted them, I had to go back to NJK iridium until E3 premium gets the correct head type for a CR9EIA-9

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.
