J.C Whitney sells a "LOT" of these SPARK PLUGS and the HARLEY-DAVIDSON Dealers sell a "LOT" of what is supposed to be in your engine "TOO" ... | ||

The Iridium Racing plug will last longer than the mileage you suggest laf - supposedly the life of the bike - the reason I chose it though was its ability to fire in adverse conditions, durability and consistency, and since I used to change plugs once a year, the relief of not having to - thats NGK article is misleading - remember they are trying to sell their product and since they can't touch the Iridium racing plug due to patents - they of course will slam the former - the fact is - on both Blasts - the first thing I noticed was the louder hit - they now have over 6000 on them and they still sound the same and when I inspected them last still looked fine. They are gapped differently because they are made differently - one look shows they are not like other plugs in a lot of different ways Independent report Iridium is a precious metal that is 6 times harder and 8 times stronger than platinum, it has a 1,200=F higher melting point than platinum and conducts electricity better. This makes it possible to create the finest wire center electrode ever. Prior till now, spark plug manufacturers have favored platinum for their long life or performance spark plugs due to its high melting point, also the technology did not exist to machine and bond iridium on a spark plug electrode (at least in a cost effective manner). Champion spark plugs have produced iridium industrial and aviation spark plugs since the 1960's, but they still sell for over a hundred dollars per plug. Just now is the technology cost effective to use iridium in a spark plug for automotive applications. The strength, hardness and high melting point of iridium make it very well suited for a fine wire plug. The primary iridium plug manufacturers at this time are Denso with a 0.4mm center electrode, while Champion and NGK have 0.7mm center electrodes. These are the best performance plugs on the market for traditional automotive use and many racing applications. Autolite has introduced an iridium-enhanced plug (the iridium content is too low to call it an iridium plug) we do not consider this in the same class as Denso, NGK or Champion. SIDENOTE: Thus far the tech's we have spoken with report no problems using iridium plugs with Nitrous.   Another article Denso: Iridium Racing Iridium racing, 12mm thread, 19mm reach, 16mm(5/8") hex, gasket seat, 51mm height, 0.4mm iridium center electrode, diagonal 0.8mm platinum ground, resistor, .024" gap Denso's Iridium power racing plugs offer the ultimate in design features. This is because they will not only provide more horsepower, but they are extremely durable even under severe racing conditions. At the heart of these plugs is the world's smallest center electrode, it is only 0.4mm in diameter. This is possible because while Iridium conducts electricity better than platinum, it is also 6x harder and 8x stronger than platinum. This ultra-fine iridium center electrode provides superior ignition performance by more efficiently using the ignition voltage to create a stronger, larger, flash front or spark. Thus you obtain more efficient burning of the air/fuel mixture and more horsepower. Because of the strength and hardness of the iridium center electrode and the fine wire(0.8mm) platinum ground electrode, these plugs are almost impervious to wear even under extreme driving or racing conditions. This makes these plugs not only the best money can buy, but also cost effective as they will far outlast several plug changes of any other plug, even on racing applications. For many non-racing applications, they may out live your vehicle, providing superior performance the whole time. A patented Denso insulator tip design, and a beveled housing, aid in self-cleaning to prevent plug fouling and bridging (carbon build-up between the center and ground electrode). The built-in monolithic resistor body offers the most reliable "talk-back" to electronic ignition systems. Nickel plated for high corrosion resistance and eliminating thread seizing. Each plug is individually packaged in its own plastic case to securely protect electrodes during shipping. No plug will give more power, however, a well designed plug will allow the motor to perform at its optimum state of tune - all things being equal - and has made tuning easier since the plugs ability is not in question any more.

Good stuff EZ... I sent an email to the tech support at NGK to ask the question on gapping Iridium plugs. Maybe we will hear something next week.} | ||
| Buellistic |
If a new spark plug is gaped at 0.024 in. and the FACTURY SERVICE MANUAL Specifications are 0.038-0.043 in., maybe the OEM recomended spark plug would supposedly last the life time of one's BLAST the way they are ridden or how long one would keep one before getting another one ... It just might take the life time on an engine for a spark plug gapped at 0.024 in. to burn to the MAX. of 0.043 in. which would be 0.019 in and at 0.001 in. a year, that would be 19 years for the life of who's engine ??? Need SPELL CHECK here !!! (Message edited by buellistic on August 25, 2007) | ||

use Firefox, and spell check is automatic, and Iridium plugs com pre-gapped - your only supposed to check that they match the advertised gap - if wrong send back as defective in exchange for one gaped at their advertised spec - that racing Iridium plug head is designed much differently than a regular plug head - a regular plug gapped like that would not work well at all - GT - JBOTDS!

When someone pays the BIG $$.$$ for a HIGH TECH. "SPARK PLUG", one would thing that even thought they are proably made in "CHINA" that their "QUALITY CONTROL" would be "BETTER" than it is ??? | ||

Their quality is without question - lol - Brian Nallin, Arron Wilson, and others have recommended them. GT - JBOTDS! EZ | ||

I could give you engineering quotes from all sorts of folks - what I'm trying to establish is a simple fact - you get what you pay for - you want the best - these are it - all the rest are just spark plugs - simple fact - lol GT - JBOTDS! EZ | ||
| Buellistic |
They are referred to as MAGIC plugs, the MAGIC comes in when YOUR money comes out of YOUR pocket into THEIRS !!! | ||
| Ezblast |
They are not magic - just top of the line - really - don't believe me - ask Pammy, Arron, Brian, etc. - they will all say the same thing - yes it is new tech and it is expensive because it uses expensive materials but it does take the questionableness of the plug out of the picture and lets you concentrate on other things - if you can drown this plug then you are too rich indeed!

Here is the whole conversation on gapping iridium plugs ------------------------------------------- Jim, For regular plugs (standard and V-power) you can gap them without any issue as they have the larger 2.5mm center electrode. The iridium and platinum fine wire plugs CAN be gapped without issue also. BUT, when gapping these plugs types care must be taken not to apply any pressure to the center fine wire firing electrode as it can break off and is not warranted by NGK. We recommend a wire style gapping tool or even a pair of needle nose to pry up only on the ground electrode. I am also including a picture of this tool type and also the procedure.  Other wise as long as the plugs are recommended as a replacement for the vehicle they will come close enough to the specified factory gap that adjustment is unneeded. Thank you.

You can't do that with the racing plug because it is designed/built differently. However for the regular Iridium style plugs that would be fine. GT - JBOTDS! EZ | ||
| Jimrich |
Ez, yup clearly from the picture you posted. There is no ground stem in which to pull on  | ||
| Buellistic |
Where it says: Can be gapped Special Tool - wire style gapping tool or a pair of NEEDLE NOSE pliers PICTURES ARE WORTH A THOUSAND WORDS Close enough Bit misleading Debated issue Clearing the issue up Do not suggest customers try | ||
| Jimrich |
LaFayette, I can't disagree. It reads from bottom up. At first the guy was like "no, they are gapped". When I responded that their website is misleading, we were a bunch of back yard tuners, and we have been debating it, I get the answer I wanted, sort of. (Missing the info EZ added on the racing plugs) If you bought the recommended plug DCPR8EIX with a .04 gap you are ok. If you are like most of us you used the DPR7EA-9 .036 or the DPR9EA-9 .036 you are still ok by +05’ Service Manual you will need to gap out to at least .038 by 04’ – Use this key to find the factory gap for other NGK plugs: http://www.crxsi.com/resources/spark_plug/partnumb erkey.pdf | ||

Oh Noooooooooo!  | ||

Not all spark plug manufacturers agree on new world order of hot to cold(cold to hot) numbering system ... ie: is it #10 to #1 OR #1 to #10 as an example ??? | ||
| Ezblast |
True but generally the higher the number the colder the plug. GT - JBOTDS! EZ | ||
| Myrtleblast |
ok. here's a question. I will be running a velocity stack, 48 primary, 175 main and shimming the carb needle .05". is this... http://www.sparkplugs.com/results_cross.asp?pid=DC PR8EIX+&x=53&y=6 the plug i would want to use? it says the fine wire is .6mm... i thought the gap should be .4mm? there seems to be a lot of back and forth arguing between people who ACTUALLY know what they are talking about, and the posts are a little older. i just want my bike to run it's best for as little as possible. Is the link I provided to the correct iridium plug for our bike? (Message edited by myrtleblast on March 28, 2008) | ||
| Ezblast |
no still a bit hot - dcpr9eix would be the suggested and is what American Sport Bike sells. EZ | ||
| J2blue |
...And the DCPR9EIX is just what arrived! But I'm in a bit of quandary because I don't have a torque wrench to use. Shucks. Off to by loctite and maybe a torque wrench. | ||
| Swampy |
NO! STOP! DO NOT USE LOCTITE! Use Anti Seize on the threads! | ||
| J2blue |
Not to worry, I meant the "Loctite" brand of anti-seize. The part store didn't carry that brand but I did use anti-seize. I hope you didn't spew coke or pepsi on your screen after reading that.  | ||

And this is what I pulled out:  | ||
