NGK plugs

[ri-gixxer]

Where do you guys suggest to buy the NGK Iridium plus for my bike part#CR9EIX, I called autozone they didn't have them and pepboys couldn't locate them by that part#, he wanted to take the plug out and he will match it up

dont even waste your time for bike plugs at places like autozone and pepboys. best bet would be to go to motorcycle shop or more likely a suzuki dealer. If you can find a place on line thats cheaper. more power to you.

those guys are idiots if they cant look in a book with the NGK # you gave them. motorcycle shop is your best bet. prolly $9 each too

I picked up a set of NGKs (CR9EK) for $8 each at Greater Boston Motorsports. Bikebandit wants $9. Not including shipping. When I opened the box to look at one of them, I had to laugh. Theyre so TINY! They look like a plug youd put in a lawn mower instead of a 900CC engine. No, wait....the mower plug is bigger!

I bought mine at Performance Cycles in Shrewsbury yesterday, damn expensive though at $10 a piece. Hopefully the iridiums are all that they're supposed to be for that price

I went to a napa first when I needed to get some. They didnt have them but they told me they could have them in a couple of days. I didnt end up getting them there because Im the kind of person that wants them now but if I remember correctly they were also the cheapest where the bike shop was the most expensive.

Denniskirk.com or other online stores, but they charge shipping, unless you buy $100 worth of stuff.

Big spark plugs just waste valve area.. that's why it's small, better performance.

Check out this comparison:



That's an F1 plug on the left.

What benefit do the irridium plugs give? Sorry for the n00b question...

[FireFly]

Iridium plugs are more efficient. Its a durable hard precious metal with a much higher melting point then platinium, nickel, gold, and silver. Its a harder metal then the others. To sum it up, they are a higher quality plug.
Advantages:
due to the properties of Iridium, the spark plugs centre electrode can be made with a much smaller diameter than with platinum, Gold or gold palladium and copper/nickel types without sacrificing service life. The spark plugs potential difference is more concentrated at the tiny Iridium tip and hence less 'spark jump' voltage is required - this can be as much as 5,000 volts less than with standard plug types. Ignition is improved and less strain is placed on the ignition system. Benefits of improved ignition/combustion include better fuel economy, increased power/acceleration and especially better throttle response.

NAPA. for sure. usually bike shops will charge 8-9 bucks a plug. just picked up plugs from napa. ngk's... and an oil filter for $18 bucks.. 4 plugs and a filter. great price.
