Very easy to install, works great and cant beat the price.

Very nice product! Works perfectly and I highly recommend it.

bought as a spare. like this brand it has always worked for me

Great spark plug. Does exactly what it’s supposed to do. I would definitely recommend to anyone looking for a good spark plug.

-m-2004 HONDA XR650L--

I noticed an instant improvement in throttle response and overall performance. I will definitely purchase again.
-m-2005 YAMAHA WR450F--

Awesome plug. As expected with OEM quality to replace original spark plug.

Awesome spark plug. Would recommend. Will be buying more.

Switched to nothing but iridium plugs long time ago, never fouled a plug again in any type of condition that would foul a stock plug. Last significantly longer than cheap plugs as well. As far as performance I noticed it ran just a little bit better than a stock plug.

Awesome plug , would definitely recommend !

When only the best will do

-m-2016 KTM 200 XC-W--

Great product. Got the product on time when I needed it. Keeps the bike running well.

-m-2019 YAMAHA YZ125--

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.

Great price and a quality product. Have been using NGK for years and will continue.

NGK reliability just stepped up a notch with Iridium Spark Plugs! Fits as expected. Started as expected. No problems thus far and I'm not expecting any!

Runs smoother starts easier

-m-2002 YAMAHA YZ250--

Very happy with this plug.

-m-2017 KAWASAKI KLR650--

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.

-m-2003 HONDA RINCON 650 4x4--

normally run the copper plugs but oem called for the iridium so thats what i slapped in, runs like it should

Worth the extra $5 to get the iridium spark plug. Lasts longer and burns cleaner.

-m-2005 KAWASAKI KLR650--

First time using this type of spark plug very please definitely boost performance

The only brand of sparkplugs our race team will use in our quads!!!!!!!

Good plug to replace OEM plug. Can't go wrong with iridium.

Fast shipping perfect fit great price.

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.

-m-2005 POLARIS TRAIL BLAZER 250--

Perfect fit and replacement for my 07 RMZ-250. Replaced the old worn out plug.

Consistent performance is why I'll spend more for NGK plugs.

Nice quality, katoom starts nice and easy ;) I have used iridium plugs on all my bikes. Can't go wrong here.

-m-2015 KTM 450 SX-F--

Its a sparkplug what can you say, works as thought no issues.

Got these for 2 stroke bike and I change them often. Burn well as long as your jetting is good.

-m-2006 SUZUKI RM250--

Great plugs! Last long and keep head cool. Price is not too bad for NGK.

This spark plug does what it's supposed to do and nothing else.

stock replacement for 2002 crf450 fit as it should

I got this a year ago and is still running strong. Installs like any other spark plug, and works better in my opinion.

-m-2005 YAMAHA YZ250F--

Good plug, replaces the familiar B9 EGR, have always used NGK plugs in all my bikes ( Honda,KTM, Suzuki,& Yamaha) over the years

-m-1981 SUZUKI RM250--

Yz125 loves these. Ngk is the factory’s recommended plug

Put this plug in about 3 weeks ago in my drz400s converted to sm. Its my daily driver right now so thats about 400+ miles. I honestly havent noticed a huge difference over the standard ngk i had been running but it seems to bog alittle less reving up from idle and it definitely starts alittle easier when its cold and damp out. All in all well worth the money so far

-m-2007 SUZUKI DR-Z 400S--

I replaced my plug on a 2010 KTM 450XCW jus this year. The bike has always started well, LI-Fe battery since 2016. However, I noticed it started to take more pushes of the button or more than one kick. I changed the plug, upgraded to NGK iridium series and HOLY WOW! One push starts and simple kicks. My old plug looked good too. Chocolate milk brown. I've got a 2006 RMZ450 and I have a new NGK iridium for that bike next! Great plug. Great starts. Better than stock always.

-m-2010 KTM 530 XC-W--

The NGK iridium sparkplug is a great product and much cheaper than the OEM plugs.

The best of the best in spark plugs for imports

-m-2011 HUSABERG FE 390--

I run this in my 86 TRX250R for a good spark and crisp throttle response. Very good spark plug.

-m-1986 HONDA TRX 250R FOURTRAX--

Worked great on my 2007 yfz450!

-m-2007 YAMAHA YFZ 450--

Never had an issue with this plug. Works as inteded and takes longer to foul than standard plugs

new fire is the best, this plug makes the fire that gets you going...

-m-2006 HONDA CRF450X--

I had to run iridium plugs on GSXR 1000, so ever since I've put them in my quads too. I run one in my YFZ 450 and just installed this one in my son's Outlaw 90. No complaints. Works good.

I ride a 2012 wr 450f it was due for a new plug. This model has electric start issues so I bought this plug in hopes of helping it fire easier. It didn't totally fix the issue but did seem to help some. Great performance, the bike runs awesome. I would recommend this plug

-m-2012 YAMAHA WR450F--

First kick super plug, flipping amazing!!!! Unperralelled to any plug I've ever used, great buy.

Sparks like a champ. Great plug for 4 strokes. Not something you want to cheap out on. When you need a quality spark, this works.

Awesome plug, run it in everything I own.Never fouled one yet......
