Good tune-upgrade

I bought these to replace my plugs at the 7500 mile interval in my 2006 GSX-R 1000. They were better-priced than the regular plugs here on MS, and went in without a problem. I've only put a few hundred miles on them, but the engine runs a bit smoother now than it did before. Don't really notice any other difference from the stock plugs. Excellent product, especially at this price.

Good Tune up upgrade

I bought these to replace my plugs for the first time at 26400 mile interval for my 2004 ZX-12R. I've only put a few hundred miles on them, but the engine runs a much smoother now than it did before. Excellent product, especially at this price.

GOOD PLUG

I put these in my FZ6, worked great. I notice that my head light is brighter after I put in these plugs. I think maybe it required less electricity or lower voltage to make the spark compared to my older original plug. My original plug lasted about 20k miles and is still in good shape when I replace it. I hope these last at least 30k miles.

Works great on '05 SV650

They were shinier than the old ones. Noticed a slight increase in power as well after installation. Maybe placebo effect? maybe the old ones were toast? Who knows. My bike seems to move more eagerly though. And that makes me happy. Great service from Motorcycle-Superstore too!

I really didn't think these plugs would make a difference in the performance of my bike, man was I wrong. My first ride was like I was on new bike, my 1200 just keeps pulling through all the gears with no hesitating just how I like it, these plugs are the real deal

Wow - This plug rocks

I have a hopped-up Piaggio 250cc scooter that has a CVT transmission. I pulled out the champion plug and put this puppy into my heavily customized machine and it made a substantial difference in power believe it or not. For those familiar with a CVT driven scooter, you'll understand what I mean when I say the belt seems to bite into a 'higher' gear at lower rpms while accelerating faster in the process. The perfect compliment to juiced up gas and a fuel injection computer on a Leo Vince pipe. I suspect the hotter spark is making better use of my 100 octane fuel formula and the exhaust doesn't smell rich anymore. Highly recommended for scooter and you cruisers better watch out. I sure am passing a lot of you guys on my way to 85mph on a 250 scooter. I'm also getting 70mpg in the process. I think I'll put some of these in my Goldwing 1800 :}

Quite nice

Picked these up when I decided to do a tune up on the bike. The old plugs were junk; a lot of the electrode had eroded away. These new plugs made a difference. Bike ran smoother, stronger; but again, this is from what were pretty dead old plugs. My coil packs actually grabbed onto a thin threaded stem. The ends of the spark plugs unscrewed with pliers, so it all worked out. Great plugs, can't beat iridium.

definitly for hayabusa

ive used these in my bike for the past 5 years and they are awesome fast start and a little extra power to boot,smooth running at idle and they scream when your throttling the heck out of it only thing is they are cheaper at your local auto parts store but if you order here you can keep riding till they show up...best bang 4 yer buck...

I can honestly feel the difference

I needed a tune up and chose to get the iridium tipped spark plugs over the standard OEM spark plugs. I could feel the difference like that (snapped fingers). I actually feel that the torque comes more suddenly and I've had to get used to holding on tighter or being ready to have the bike leave me. I haven't noticed any differences in gas mileage, but when they say that your output will increase with these spark plugs, they are not just putting up persuasive advertisements.
