Just wondering if anyone has put a set in their brute? I did some research and the claim is that because the center electrode is a lot thinner it's like adding about 5000 volts to the ignition system. Not sure I believe that but the Father-in-law put a set in his harley(yeah I know) and says it seems to run and idle a little smoother. Any opinons?

The main goal of iridium plugs is longevity!
There's also some literature that state the 0.7mm electrode is the perfect size for a number of reasons. There's also literature that states going smaller tham 0.7mm is detrimental to the burn process.

Being in the car repair indusrty, I've always found that whatever the manufacturer suggests is alway the best option.

I've taken out way too many brand new plugs and installed OEM specified to solve a driveabilty problem.

Not saying you have to buy Kawie labled plugs, but if NGK makes them, use NGK. If the OEM's call for iriduim, use them only, if they call for standard plugs, use them only.

For what you are going to save in $$ or gain (unless your rebuilding the engine or adding something), do you really want to be towed out 5 miles back on the woods by some Honda?

I change the plugs on mine every year, just because it's cheap and easy (like the wife) and I don't have to worry about it.

and your parT # (NGK) should be CR7E OR STOCK # NGK 4578.
