NGK Iridium Sparkplug

These are the exact factory recommended for a KTM 500 EXC. Why deviate from the factory recommendation???

Of good quality. I have used these plugs on my other rides and vehicles. It's kinda expensive but worth it.

Great spark plug. Purchased many times. They seem to last longer then others.

Everything worked as it should and was very easy to install. Appears to be high quality.

-m-2002 HONDA CR125R--

I use these in both of my bikes. I have Never had an issue with the plug but I always carry a spare in my tool pack.

-m-2017 HUSQVARNA FE 350--

Definitely made the bike feel better when I put this in.

Fit perfect. To those who are uninitiated like me, theres a cover on the top that you have to screw off before install. Been fantastic so far. Months of hard riding and still works perfect

Picture threw me off but the right one came ! Just make sure you have the correct part number from your service manual

Application for my 19 Harley Road Glide Ultra, CR9EIX. The newer M8 HD's don't have the Ion Sensors in the spark plug cap so these work fine.

Ive always liked ngk spark plugs, great addition to my kids four wheeler

-m-2008 YAMAHA RAPTOR 80--

Used one for 56hrs on my son’s 2017 KTM 85sx even through a lot or racing and it still looked good after that.

Great product, excellant price considering what dealers in NZ want you to pay for these.

-m-2017 SUZUKI RMX450Z--

Works great no problem starting with these plugs.

-m-1997 KAWASAKI KDX220--

Extra plugs come in handy. Use these all the time work great!

Seems like a perfect replacement for the previous spark plug that was in my 1997 Honda FourTrax 300. It came already gapped to the factory recommendation.

Great product and very affordable. I highly recommend

I can definitely feel the improvement in throttle and performance.

Installed a new coil and figured it was time for a new plug as well. This is what Honda put in it to start with, figured might as well stick with it.

Expensive compared to other spark plugs, but it’s nice to not have to worry about fouling a plug once you put on in your bike.

New plugs didn't want to run or idle very well. Took back out and installed the 3 buck ones that were in it originally. Runs like a dream now. Save your money on these.

-m-2014 CAN-AM Commander 1000 XT--

Great for the price have had no problems instantly fixed back fire problem when switched

Been using these for years and have been pleased with reliability.

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

-m-2008 YAMAHA YZ125--

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 !

-m-2009 KAWASAKI KLR650--

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!

-m-2008 YAMAHA TTR125L--

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.

-m-2016 KTM 250 SX-F Factory Edition--

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.
