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

Do not use this plug in Polaris Trailblazer 250
This is the recommended plug for the Trailblazer 250, so I tried it. In about 20 minutes of riding it blew a hole in the piston from preignition. This is the only change that I made and been riding the machine for years in deserts, mountains, hot and cold climates. Always use premium gas on 2 strokes and even with that it blew a hole in the piston. If you look at the standard plug you will see that the porcelain around the electrode is thicker than the iridium plug. If you want an iridium in a 2 stroke drop down a couple of heat ranges and maybe save your engine. They work fine for me in 4 strokes.

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.
