ngk spark plugs

Just thought i would share & hopefully save someone a few quid. I am going to replace the spark plugs as the current ones have been in 4 years now. I rang a yamaha dealer & they quoted £10.60 per plug . So i ring a place called s&j motorfactors they quoted £3.40 per plug & even offered to drop them off at work for me .

That is a really good price , cheaper than anything I've seen on ebay . Do you have their details ? Would be handy for future use .

Also , speaking of spark plugs ..are NGK the only park plugs suitable for the Cat ? It seems most bikes :cheers: use NGK.

The other spark plugs you can use are nippondenso u27esr-n but i have not tried them.

I work for a Motorfactor and we supply NGK plugs, which are very good.

However, there are many other manufacturers of plugs that are just as good. Bosch, Champion also spring to mind. Most manufacturers will make plugs for the Cat, you just have to get them to cross the part number of the OE number of the Cat plug to their own brand.

It could pay to shop around, I certainly wouldn't stick with Yamaha plugs.

I use the NGK IRIDIUM IX-spark plugs - and they are briliant

What is the difference between the IRIDIUM and normal NGK ?

puuh - that is difficult for me to describe in english

They have a longer life, because they don't soot (?) so much (double durability).
The consumption is a little bit lower because of the better spark ignition.
With the iridium the behavior at starting the engine is better.

And of course - the price

8,75€ to 14,95€ :idea:

Sorry - but technical english is not so easy :geek:

I would say you described that perfectly well toni. I could not have done any better & i am almost english & also a technician
