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++.

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.

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?

Best plug you can buy!

Iridium plugs offer a noticeable improvement over standard plugs in my bike. It starts quicker and idles smoother. Gets a little better gas mileage too. Now these plugs won't give you 5 extra H.P., what they do give you is enough to warrant them.

Longevity Update on NGK CR8EIX

For those who want to know. I ride a DL650K6 and ran my first set of NGK Iridium plugs for 28,000 miles with virtually no signs of wear. Since I was doing the scheduled valve and throttle body check/adjustment, I installed a fresh set. I have since put 38,000 miles on those plugs and they still look fine. Talk about cost benefit!

iridium plug

initially tried these in a '78 yamaha xs650e after reading about improved performance obtained by Heiden tuning, noted a little slower to start, but better overall performance ( smoother acceleration and @ idle), subsequently tried'em in "07 dl 650 k7 with perceptibly smoother running engine result.

Iridium Plugs on V-Strom 650

When plug changes are a PITA like on the V-Strom, it's nice to have a plug that will last 25k+ miles. Some Strom owners have reported many more miles than this without any trouble. Fancy plugs don't improve performance significantly unless the old ones were really shot, so any increase in performance is probably imagined. Buy these anyway for the longevity.

NEEDS TO BE STANDARD ON EVERY BIKE!!!

I replaced the standard plugs in my FJR1300 with these and my mileage went from 38-39MPG to 41-43MPG and the power is awesome!!! The front end lifted several times this week avoiding NY and NJ drivers without maxing the throttle!!! You've got to get these for your scooter!!!

excellent product; great service from MSS!

I just installed these plugs on my 2006 Yamaha FJR1300 and synched the throttle bodies at the same time. The engine is much more responsive and runs smoother at idle. It's almost like adding a mini turbo boost. I'm just wondering why Yamaha didn't put these on the bike as original equipment. They are so much better.

So far, so great

I put these plugs in my '09 Suzuki V-Strom DL650A at 7,500 miles. I've only put another 1,500 miles on it since then, and it may be my imagination, but it feels like the engine is running "smoother." (not that it was ever rough). I think my mileage might've even gone up a bit. No idea how long they'll last, hence the 3-star rating for "durability."

Not sure if there's a difference

Now, as most of us know, the improvement felt with any new plug is mainly due to degradation of the old plug. I bought these mainly for the anticipated longer durability of which I can only read about. If they last twice as long, then they are worth it because even though they cost twice as much, the real savings is in the labor of changing the plugs, which on the 2002 Suzuki SV650S is significant.
