Wayne Katsura Morgan City,  LA NGK Iridium Spark Plug I'm a 'Mature Gearhead'. Plugs are installed on my '06 Suzuki DL650K6 'Wee" Strom which I ride every day in any weather. Standard plugs required replacement every 14,000 miles and cost $5.00+ each. I had just completed services to the valves and trottle bodies (including new plugs)and the engine was running great (always did). I've been wanting to try Iridium plugs, but all the places I inquired at sold them in pack qty only. I didn't want to spend $40.00+ and find out the bike didn't like them. Then I noticed Motorcycle Super Store sold the Iridium plugs per each. I ordered a set and immediately installed them upon receipt. I immediately noticed a smoother idle and the roll-on performance 'feels' improved. Fuel mileage improved by about 1-mph. I checked the plugs at 9500 miles and am impressed; clean and virtually no wear. Wonder if these plugs will go 25,000?

Yorgo Miami,  FL Now we're talkin Wow! I never thought a spark plug would make a difference but after installing this new IX plug I hit the road for a test run. Right away I could feel a difference. The engine came alive and felt happy. Now it revs a little faster, has a little more power, and responds quicker. I can't explain it but it works.

Scott Las Vegas,  NV GREAT Spark PLug!! I bought a NGK IRIDIUM plug for my 2002 Kawasaki Super Sherpa 250cc dual sport bike not knowing really how much it would help. WOW. Amazing. The bike cold-starts alot better, runs much better/stronger, and seems to idle much better. Overall, $10.50 well spent. I give the IRIDIUM plug an A++.
