Comments On Mar 08, 2013:I felt a bit more zing and notice slight increase in throttle response with this plug. It could be placebo, but even if it is...it was worth the $4 more for this plug over the regular.

Comments On Jan 11, 2013:It spark plug works well but I have had to recently had to replace my top end because of a cracked piston. I am not saying this plug caused it but I have since switched because I have never had any piston problems while using and standard NGK plug.

Comments On Jun 04, 2012:I love NGK plugs run them in everything from my truck to my lawn mower, so when I found this Iridium plug for my YFZ 450 i had to have one.... no clue if any performance gains are ever to be had, but it should last even longer than the standard plugs

I think i get a better fire, and hopefully a longer service life from this plug... but was it worth almost 3x what a standard plug cost that is for you to decide

Comments On Sep 02, 2012:I don't think a plug like this is worth the extra money..They are only as good as the ignition system, people think you add one of these and the spark will increase by x10 what is is not, not true. I have no problems with it it works, just not worth the extra money to me,.

Comments On Nov 10, 2011:Most power and fuel efficiency hands down out of any plug I have tried. No reason to cheap out here. If you demand the best for your bike, run NGK Iridium.

Comments On Oct 27, 2011:This plug is awesome, you can run it all year if your jetting is spot on and not even worry. In fact I've had one in a bike for over two years and it still runs like an ace! The plug is definately worth the few extra bucks.

Comments On Jun 03, 2011:This plug did make a better throttle response off idle than how it was with the stock plug. So to buy it for a performance increase over the factory plug you may be disappointed. The reason I bought it was for it's longevity and reliability. I use it on my Raptor 700 and it runs great I've run this plug for 2 years now and the electrode is still like new. But I would expect it to for how much more it cost over the stock plug. So if it continues to perform another two years then I guess I got my monies worth.

Comments On Jan 13, 2011:These are the best 2 stroke plugs period. They don't foul easily and last a long time if your bike is somewhat jetted correctly. They are a little pricey but will last at least 3 times longer than the cheap ones so it evens out.

Comments On Dec 07, 2010:These plugs seem to foul much easier than the standard plugs. I can run regular plugs in my bikes with no problems and when I switch to the iridium plug it fouls right away on the first ride. I'm sure they work great if you are willing to constantly re-adjust the jetting and keep it precisely dialed in or just on the lean side. Otherwise, use the standard plug.

Comments On Aug 18, 2010:Its not perfect but way better than what the manufacturer calls for. I dont have time to make sure that the carb is perfectly tuned. When I have time to ride thats what I want to do. This plug will foul but will last alot longer if your carb isnt just perfect. Plus you can clean it with some plug and contact cleaner to get a little more life out of it.
