NGK 5044 Iridium IX Spark Plug - BR8EIX, 4 Pack

Have been using ngk plugs in my Mx bikes since 1974Great plugs and last a long time. The right plug for the job!

Awesome

Calls for BR8ES or BR8EG but three are better plugs and don't fowl or burn out quickly. Fits perfect and priced right for a 4 pack.

I switched the turn signals & brake/tail lights on a 2001 KE100 motorcycle to LED's and as a result I had a lot of ignition noise that the LED's picked up. These resistive plugs solved that issue (the stock plugs were non-resistive type). Anyway...... served the purpose & no noticeable effect otherwise with engine performance.

High performance spark plug

I use this same spark plug size on both my 88 Yamaha blaster 200 and on my 03 Kawasaki kx250. These two strokes love it. This and a carb clean and a filter they start right up even after sitting for a year or so

Excellent plug .... Fits 2001 cr 250 and 2001 kx 250

I Have a 2000 KX125 which is stock with a NGK BR9RS plug and had tons of fouling problems so I switched to the BR8RS (hotter) which did have a slight improvement. So in typical troubleshooting fashion cleaned the Fuel system and Carb, replaced the jets and adjusted the fuel mixture slightly leaner 32:1 to 40:1 (don't ever go too lean unless you want to replace the top end all the time) and still fouled plugs. So I figured I'd give this a try. Yes it is more expensive but what a difference. With only changing the plug I solved all the fouling issues I was experiencing. Even at the correct fuel mixture hasn't fouled the plug yet! Definitely worth the extra $. Not to mention saving you all the time "troubleshooting". Even if you are not having any issue I would recommend giving one a try. You won't be disappointed.
