Why buy anything else.
The best spark plug hands down. Outperforms the stock spark plug. And any other NGK or Denzo spark plugs on the market. After installation the bike started up a lot smoother. If you doing a tune-up this is a must-have.

Spark plugs
A lot less expensive than if you bought it at the dealer. Also easier to get than having to go to a dealership, hoping that they have it in stock or to a local parts house, which won't have it.

Worth the up-charge vs regular sparkplugs
Worth the extra $5 to get the iridium spark plug. Lasts longer and burns cleaner.

Does the end screw off of this plug? This end want fit my wire. I need the end that is small with threads.
Steven H on Jan 9, 2018
BEST ANSWER: Been a while since I've bought this one but have used NGK for years and cannot remember one that did not screw off exposing the tip you need.
Which are better overall these or the e3 plugs?
Bailey A on Dec 26, 2018
BEST ANSWER: Without defaming a brand, in my opinion the solid brands from a overall reliability and performance point of view would be NGK, Denso, Bosch, I feel that some of the other brands are purely marketing. An example would be split fire, they guaranteed a performance increase but if you read the guarantee it voided if you dyno tested... lol so how do you quantify performance. I’d recommend sticking with ND or NGK for a bike.
Does this plug come with a terminal nut?
Rolando H on Apr 2, 2018
BEST ANSWER: I don't believe it comes with a terminal nut. If I recall, it only comes with a threaded terminal stud with a terminal threaded onto it. No nut though.
Is this recommended for a 05 crf450r with a13:1 high compression piston installed?
A shopper on Nov 16, 2018
BEST ANSWER: This is a question for a professional performance engine builder. You will most likely need to adjust your heat range due to higher combustion temperatures. I use these in my 2 stroke for better resistance to fouling.
