Spark Plugs

[Liveware Problem]

Standard or iridium, does it make much difference?

Is it just a case of iridium plugs lasting longer, or are there other benefits?

[Ian Frog]

Certainly does to your wallet.

If there is no specific reason to fit them I.E warranty or ECU mapping being specific to the model then I wouldn't.

Its mainly about lasting longer.. for example on my bike thats a 32,000 mile interval.

I've tried iriduim plugs and I can't say I've noticed any difference - other than the price. I'm sure they do last longer but since plugs do fine between the usual service intervals I haven't found any benefit.

They're best used on bikes where accessing the spark plugs is a massive faff. Which is why they're OEM on the Africa Twin.

Good little read up there

I did use iridium on my Himalayan when I had that. Made a difference in the throttle response on the single cylinder Himalayan and reduce warm up times somewhat and provided slightly better mpgs. Didn't make an issues for me pricewise as I only needed one. I'm guessing it wouldn't make much difference on my tracer .

plug changing on my bike isnt a problem (about ten seconds to change it)

I've used them on anything I've modified with a turbo, never had one fail or disintegrate and in the general scheme of things even 6 at a time they are one of the cheaper mods to make, can't say I have ever noticed a difference performance wise, it's been more the reliability and safety margin increase.

Iridium plugs unlock infinite horsepower

Iridium plugs unlock infinite horsepower

 

FFS don't tell that to the 17 year old's on their 125's

[skyrider]

dead right they would be fitting it as a go faster bit

[Guest Richzx6r]

Could always paint a stripe down the sides of the bike they will add more than 100bhp just by themselves

[skyrider]

WILL AN IRIDIUM SPARK PLUG BE BENEFICIAL FOR MY PARTICULAR ENGINE?

This is very subjective. The vast majority of vehicles/engines will benefit from replacing a standard spark plug with an Iridium spark plug. Most benefit will result if:

There is a very close Iridium spark plug match for your standard spark plug (i.e. overall design is very similar)

The standard spark plug you are replacing is a basic copper plug (the Iridium plug will then be a more significant upgrade)

The engine has a large cylinder capacity and a large number of cylinders

 

Define large?!

I would define large capacity as say over 3.5liter maybe it does sound very vague as for america sub 4L is probably classed as small where over here anything bigger than 2L is classed as a large capacity engine guess it's down to personal taste?

probably a proper bike and not a 125

I put some Denso ones in my CB250, it was noticeably more perky for about 50 miles and then went back to being the same as it was with copper NGKs. Then after about 7000 miles they started arcing down the porcelain so that was that. The NGKs lasted 25K..

Wouldn't bother again!
