Iridium sparkplugs?

[firefighter]

Do you bother spending the extra on them? Is it really worth it?

Obviously my bikes getting a service.......i'm getting new plugs as I don't know when they were last done.

Is it woth spending extra on the iridiums or should I stick with the good old plain ones?

If it is worth spending the extra, what gains do I get to justify the price?

Also need some brake pads......

I'm wanting either Ferodo or EBC sintered HH pads......Which is your preference? (they're the same price roughly)

Lol. Nah, I just thought there would have been some sort of significant difference, at $10+ ea more expensive. Like smoother running etc.....

From my research, they are worthwhile from the point of view that they basically don't wear out the electrodes like 'ordinary' plugs, so they'll last for years and years. However (but!) I've laso read (but can't validate this) that they are also prone to becoming unserviceable if they get fouled.

Don't expect any real change in performance or anything like that with them.

I had some in my VTR1000, just because someone else raved about them. Didn't notice any difference. I've now got some in my VFR, solely because they were only very slightly dearer (from Repco, amazingly enough!) than what I was quoted at Cycletreads for ordinary ones, and cheaper than what I was quoted for platinum-tipped ones. Cycletreads didn't have any in stock when I asked, Repco didn't either, but ordered them in and they were there in less than 2 hours. So, I figured it was worth it.

Awesome cheers for the info.

I take it the price difference was less than $10 per plug? (i've been quoted a $40 difference in the total price)

If the plugs are a pain to change in your bike like mine, they are worth putting them in.They are expensive -was quoted $48 each here, but picked up a set of 4 for $88 on ebay.

From memory, it was $126 for four plugs. If you know what the standard plugs are, the iridium ones have a similar number but with an IX in it; for the VFR, the standard plugs were CR9EH-9, the iridium ones are CR9EHIX-9.

I've got them in my sem fiddy.
I reckon the bike feels a bit chrisper with them... and they last for yonks!
Fit and forget!

Yep, about the one real benefit of fitting such things.

I had a set of iridium plugs in my FJR for a while. I couldn't tell the difference between them and the stock NGKs.

Easier starting on two stroke dirt bikes. Other than that I wouldn't bother.

I can't believe the prices quoted, or maybe I just got a really good deal at $11.50+gst

They didn't fare too well in the triple though and I've since gone back to the stock CR9EK.

[bsasuper]

They wont feel any different, but they will last longer, the reason I use them.If you like to change out your standard plugs every 5000k, fine, me I dont.

I paid $90(4) for my FZR at part sponcership almost cost price so are we talking the same plugs or did someone put the wrong price against yours.

[slowpoke]

Depends why you are considering them.
If it's for performance a better option might be to go with (from memory) NGK CR9EK's. They are "ordinary" plugs but extend slightly further into the combustion chanber, thereby slighty increasing the compression ratio which equals cheap power. It's not much but it's cost ya absolutely nothing if you were going to change the plugs anyway.
