Got a 2016, 2017, or 2018 KTM 450 XC-F that needs a fresh spark plug?

This NGK LMAR9AI-8 Iridium plug is the exact one you need.

This isn't your average plug – it's a high-performance laser iridium design.

The tiny iridium tip allows for a stronger, more consistent spark, which translates to quicker starts, smoother idling, better throttle response, and even a bit better fuel efficiency.

It also has a platinum disc on the ground electrode to fight wear, so it lasts way longer than standard copper plugs.

The whole thing is treated with a trivalent metal plating to prevent corrosion and seizing in the cylinder head (a lifesaver down the road).

If your bike is feeling a little sluggish, hard to start, or just due for routine maintenance, swapping in this premium plug is one of the best and easiest upgrades you can do.

Keep your KTM running sharp and strong with genuine NGK quality.
