PLATINUM PLUGS

[excess.11]

All so true Coops..........on another aspect of plugs.....race tuners index their plugs......of which some major bike manufactures  have done .
Every little bit helps. But i m thinking that would be a harder task to detect any seat of the pants difference than the infamous Peter Brock Energy Polariser.

Good to read all comments remember that to achieve optimum performance everything has to be balanced as well including shims. Spark plugs no matter what they are will not achieve top results if everything else is below par I adjusted and balanced and bike runs better with platinum including fuel consumption the figures I have lost since my return from the island but its still worth the effort to keep the ole girls purring . Just had reports on Toy Run here last Sunday just over 12.000 bkes on Sunday trouble with shit location for journeys end. No 1100's just one 850 needing some TLC but will be my last run ole girl got a bit hot so much hassle at intersections thers one thing came to mind with those numbers which was down on last year bikers have a voice collectively .  Coops

 even piped and jetted with dynacoils and free-flow filter,  which gives a bit of a boost mainly at big revs full throttle,  the difference in horsepower isn't massive,  there's not a cat in hells chance of a rider seeing,  hearing,  feeling or noticing the tiniest tiniest most miniscule difference between a million dollar sparkplug and their tatty old champions.   UNLESS you tell them...  THEN  miraculously all of a sudden a big lump of extra horsepower is likely to appear..

From what i read into it...they are nt claiming you ll instantly recieve another 10 kw or even by this quote....any kw advantage.....
"It's worth noting that spark plugs can't increase the potential power that an engine can generate but a more efficient spark will provide more efficient combustion and associated performance and economy benefits."
I recently changed out a set of platinum plugs due to lowering fuel economy in a car i have , after 75,000....kms..and they still looked reasonably good.....not half eaten away and burnt out as some standard plugs show after their use by date.Nothing wrong with manufactures using superior materials to make a longer lasting plug that you don t have to regap during it s lifetime.....of which i most never got more than 6,000 kms out of the standard BP6ES of which the electrodes were eaten away and burned out.
Consistency and longevity of a high voltage spark through using better materials is nt Hokey Pokey.
I wonder if some people have paid a lot for these plugs and installed them without balancing and using a colortune unit or checking valve clearances to optimise performance............installed them........then expected some plainly obvious changes! Like stopping that annoying backfire on change down......or easier starting..........or....better fuel economy and responsiveness etc.
I see   improvements in performance through minor subtle changes all adding up .....not.....throw in an expensive plug....do nothing else to the bike...then complain because you ve spent a lot and nothing earth shattering has changed.!!!

love these high grade technical debates with all their well reasoned arguments and  the "independent" manufacturer's surveys and comments.

Very stimulating

ADVANTAGES...



"less 'spark jump' voltage is required - this can be as much as 5,000 volts less than with standard plug types!"

 OH YAY,  WE CAN ALL REMOVE THE POWERFUL STOCK COILS AND REPLACE THEM WITH WEAKER ONES AND RUN A WEAKER SPARK THEN ..LOL 


Notable properties of Iridium are its melting point - approximately 2450 degrees C, considerably higher than Platinum, and it's strength - approximately 8 times that of platinum!

MEANING WHAT??  WAFFLE!


A poor spark from a "WORN" or "LOW GRADE" spark plug will reduce efficiency. An Iridium plug will produce a more efficient spark!

NO SHIT SHERLOCK!!


Iridium - an incredibly hard precious metal...

WOW!    BUT SO WHAT???   LOL

Here are some facts..........

I tend to agree with pgnz
A spark is a spark is a spark no matter how cheap or expensively its created.
I get plenty of forward propulsion with my el cheapo run of the mill NGK's

HeHe, you don't need tests,  a sparkplug can't "deliver higher horsepower"  that's such a crock of shit, you're only still getting the same half mm spark from the coils no matter WTF brand plug is in there. (BTW The two plug per cylinder is a totally different scenario)   Fancy expensive sparkplugs on their own don't "improve performance" at all,  you'll find the people claiming they do are just dreamers living in a world of make-believe LOL. 


Enhanced Ignition Efficiency  CRAP!

Better Acceleration   COMPLETE BULLSHET!

Faster Starting     CRAP!

Smoother Running  CRAP!

Longer Life  POSSIBLY...

Better Fuel Consumption   CRAP!

Factual info on.............kms per tank.....any tests?.....any comparison results? Any temp tests before and after changing? Were the iridium plugs set up with a colortune to optimize performance?.........A dyno test with standard........then iridium plugs? Exhaust analasys?
Small subtle changes can add up.........especially if you were running a bike in the Castrol 6 hr...did the twin plug designers know something we do nt ?....and were part of the catalyst for better plug design??

These are the manufactures claims............

 Enhanced Ignition Efficiency!

Better Acceleration!

Faster Starting!

Smoother Running!

Longer Life!

Better Fuel Consumption!
.................The result are spark plugs that require less voltage to spark, burns fuel more efficiently, sparks at leaner air/fuel mixtures, and delivers higher horsepower and better fuel economy.
What are the accurate facts and figures ?....not just opinions or heresay.
Pricing is between $7-12......each........
Guinea pig up.......i say!!!!!!!!
Where are the Mythbusters when you need em??

I have had a set in mine,, {iridium}

all I'd say is don't waste your money,, unless you're after a tenth of a poofteenth of a horse power, or a millisecond over a quarter, I found there to be no discernable difference, not worth the $27 give or take a plug anyway,

on top of that, {my own working out they're not worth it} I was told by "my man" in the know, to take em out and leave em out, he didn't say why, I didn't ask, he just said don't run them,, haven't run them since,, haven't missed them

Thanks Coops.........one thing that has stuck with me regarding plugs and these bikes was the race bred innovation of 2 spark plugs per cylinder with some of the earlier teams that won major races here in Australia.it would be great to know what if any factual advantages were gained by doing this.Also other than general opinions............some feed back off anyone who has actually tried iridium plugs in their bike........not the blah blah feedback about..............i once heard of.......... or...........i once knew........etc etc ...........

Said i would get back about plugs I forgot Jeff. Since a colortune and carbie balance bought a set of Platinum plugs about six months ago. Well Im impressed on arrival at Phillp Island had a quick look to see how things were going plugs looked good slight oily appearance no dramas engine starts first go on the button and may be abit of everything done ie balance colortune  etc accelerates better than b4 . They were matched to NGK as close as engine runs what I assume is normal temps. If you own a Magna and due for rear plug change install the back plugs with Platinum much cheaper and better than Iridium plugs. Coops
