Hey guys, and yes I did search the KV. What are the best plugs to buy for our XB's. I have a 12. Any thoughts. | ||
| Gentleman_jon |
Denso Iridiums. Daves usually has them in stock. NGK iridiums are good too. | ||
| Typeone |
i don't know about 'best' but i like my NGK Iridiums. | ||
| Teeps |
Are these Iridium plugs installed because the original plugs are worn out or is there a problem with the original plugs? Can a Horse Power gain be quantified by other than the Butt-Dyno? | ||
| Typeone |
i use NGK because i've always used their plugs in my bikes, brand loyalty there, but i went with the Iridiums because they're virtually foul proof. i ALWAYS warm up my bike for ~5min before taking off but i tinker a lot, especially with devices like the TFi, so i didn't want to risk fouling a plug for some stupid reason. i've never been one to believe a plug will increase HP. (at least to the point where it would be 'felt'.) | ||

The iridium plugs are more resistant to fouling. You won't gain hp by changing brands of spark plugs. Dyno error from run to run and dyno to dyno is larger than the gains claimed by most of the plug makers. At least on a street engine with a stock motor and single plugs  | ||

What about the Buell race plug. Also what are the part # for the NGK Iridium's and the Denso Iridium's. Also what kind of price are we looking at. | ||

I use these and they work great.  | ||

I'm a huge fan of NGK plugs. I've been using them in everything for 20 years or more and it's a rarity if one ever fails. Even when they come out of an engine that's done many thousands of miles between plug changes. In my Buell I've run most of the usual stuff and NGK's are the only plugs I've ever had reliability from. I say that because others, Champion, HD, Splitfire, Accel and more have actually failed when I've used them. Rocket | ||

I have the buell pro series plugs(splitfire triple plat). seem to work fine. I dont know if its my imagination but I seemed to have gained 2-3mpg after installing them. only other thing I did was use a cap full of redline fuel system cleaner per tank and reset the TPS | ||

Are Denso and Iridium, standard or metric? | ||
| Gentleman_jon |
The Denso Iridium plug for the XB Series is model: IXU24 The plug is the same size as the stock plug, and uses the same wrenches and installation technique. It has a 12mm thread and 19 mm reach. Technical details are available on the Denso web site: http://www.densoproducts.com/resultsAppOther.asp?o therMotiveID=57640&mfid=3 The advantage of iridium plugs is that iridium is 6 times harder, 8 times stronger, and has a higher melting point than platinum, the other high quality spark plug electrode material. This allows the plug to be make with a very fine wire center electrode, which improves performance. List price is $11.91 each. | ||

Another advantage of the iridium plugs is that they just do not foul. I'm not sure if it is due to the thinner elctrode or or whatever, but they will not foul and should last for around 15,000 miles. The NGK's do not come supplied with the screw on plug cap, so you will need to fit one when using stock leads. The NGK part number is DPR9-EIX9 | ||
| Bigbuell |
I went to the Denso web site and they really don't say that they cover the 2003 to 2006 XB's. Please clarify I'm sooooooooooo confused!!!!!!!!!!!!!!!!!!! What to buy! | ||
| Gentleman_jon |
Shawn, You are quite right. The Denso web site does not list XB models.Don't you just hate that? This is quite common on accessory manufacturers sites. As you can imagine, the list of makes and models is just about endless. That is what we have Bad Web for: brothers sharing knowledge with each other.  The IXU24 specified for the earlier years is the one to use for the current models as well. | ||
| Treadmarks |
I use the NGKs, their new part number is 2202. | ||
| Bigbuell |
Thanks Gentleman_jon, thats what I needed. One other thing, are these plugs a different heat range than the stock ones, or the same. | ||
| Beachbuell |
HD's 10R12APP, part number 32334-05 is what I run without a problem. These are the high end platinum plugs, resist corrosion, special coated for easy in and out, better combustion also.... Or so this is what is claimed HD/Buell. Something like $7.95 each retail, I think. | ||
| Pwnzor |
The plugs I pictured above, regular old HD plugs, not platinum, have never fouled on me in 28,000 miles. I took the old ones out and I have them right here as spares in excellent condition. When they came out I was like "I didn't need to replace them but since they're out, what the hey". $10 for the pair. I replaced them with the belt (also didn't need it) at 10k miles. | ||

brisk model BOR 14 LGS....."M A G I C!!!" ping me dealer info....Or go to brisk website for area dealer. Live in phx,az and installed in july with 118F temps and pings bad....no more ping even in higher gear and bogged at low RPM! | ||
| Huskysm450r |
I'm running the BOR12LGS Brisk plugs in my XB9SX. Runs great! | ||
| Bigbuell |
Hey guys, never heard of brisk plugs before, dose it really help with the ping. And what is the difference between 14 and the 12s. You have my attention. | ||
| Sgthigg |
got a part#? | ||
| Huskysm450r |
The difference between the the BOR14LGS and BOR12LGS is the heat range. The 14 is slightly hotter than the 12. I did not experience any pinging/detonation on my XB9SX with the stock plugs so I can't speak to that. I do run the Brisk plugs in my other bikes (husky 4T singles) and they run noticeably better with these plugs. http://www.briskusa.com/products.htm#premium | ||

I tried the Brisk plugs in our race bike for a while, and whilst they worked just as well as the NGK's I don't think they worked any better. There was certainly no discernable improvement on the dyno, and we ran both Brisk & NGK plugs on the same day to see if we could identify any difference. For the extra cost involved I wouldn't bother fitting them over any of the others. | ||
| Typeone |
hmm, hotter Brisk 14 series plug = no ping. doesn't make sense to me. was that the only change you made Thunderheart? speaking of all this plug stuffs, does anyone index their plugs on the XB? is it worth it for a street bike? i've been thinking of doing it this winter, just for the sake of efficiency but if its a moot mod, i won't bother. still would like to learn though. | ||

A while back I was "googling" indexing of spark plugs. Best I could determine it just wasn't worth the hassle. Might be a bigger deal on a really high compression engine.
