Magic moonbeams and fairy dust

[T»n»r»]

Looking to put a new set of spark plugs in the my 955, but why do people buy expensive Iridiums over standard NGK's ?± would I notice any difference in general use or is one spark pretty much like another to an ordinary road user?



On the subject of the speculative, cop a butchers at this: http://cgi.ebay.co.uk/CAR-FUEL-SAVER-SA ... dZViewItem seen a few of these from a fiver and can't quite manage to believe the claims. You would think that if they worked, all vehicle manufacturers would fit them as standard. I'm still kind of tempted (mainly out of curiosity) for my European tour this year with fuel prices as they are ?± what do you think?

When Bosch platnums came out I tried a set in a truck I had and then again 15 years later in a jeep. Both times I took em out and threw them in the trash and went back to regular NGK`s or autolites. In either case it ran bad, idled several hundred rpm lower and lost several miles a gallon. Obviously a heat range issue it would seem. Maybe they only work in German cars :roll:

Whenever these sorts of things have been subjected to independent tests (which is rarely as their suppliers won't support them) they turn out to be useless. The "science" behind most of them is as you suggest based on fairy dust.

I've run Iridiums in a couple different bikes.  You won't be able to tell any difference in how the bike runs, they just last longer.  I like to use them in my SV so I can ignore the spark plugs between valve adjustments.  After 15,000 miles it's running a little rough with the standard NGK's.  With the iridiums it's still running great.  They'd probably go 30,000 miles if I left them in there.  I'm too anal for that though.

I'll throw a set in the Tiger when I do the valves in a month or two.  I get them through ronayers.com, for about $7 apiece.

Iridium plugs also reduce the load on the ECU by about 5000 volts. Which is No bad thing on a Tiger.

I also forgot to mention that some years back I tried the rare earth magnet trick on a Mercedes 18 tonner over a distance of 50,000 miles and noticed no differance whatsoever.



I still have them though on my trucks just for the feel good factor and the fact that I dont want to bin something I paid 40 odd quid for.

The mileage covered since fitting these gimmicks is something like 1 million kms and the truck still returns the same mpg as it always did.

27% saving in fuel costs! my ar-e!.

Snake oil for motorists!!!!!!!



The very best that can be done for any engine is regular maintainence and the use of a good quality oil.



Bikers generally have a greater respect (and love) for their motors and tend to be suckers for additives and gadgets for protecting and extending the life of their bikes

I've been using Iridium plugs for the last 9000 miles (fiited at the 24K service). Unfortunately, I fitted a K&N air filter and a 19 tooth front sprocket at the same time. So I don't know which one is responsible for giving me 20 more miles per tank full.

I used them in my XJR, and in a couple of other bikes i have know. the biggest pluss is they last a lot longer than normal plugs, and as a small plus it takes a little less voltage to get a clean spark. cant say i have ever noticed any diff. they allways run realy well and never had a problem with 1. i will replace to these when they next need replacing.

but not worth changing just for the hell of it.

I use Bosch platinums in my Beemer and NGK Iridiums in my tiger the difference being the Bosch are a third of the price!!,performance wise there's nothing in e'm.

I've had the same set of NGK's for 8 yrs and 35000 miles inmy Thunderbird Sport and sheruns just aswell as when new,actually better than new. No reason the plugs shouldn't last 60000 or more

Thanks for the feedback, Decided on plain old plugs and got a cracking deal, all three for £6.48 delivered:

Will give the magnetic gizmo a body swerve then. I seem to remember something about it being a British patent developed to extend the range of  WW2 fighters escorting bombers, but that may well be just rubbish along with the product.
