do you have to go to a harley dealer for xb9 plugs? Are the same plugs used in other model bikes? I don't supposed an autoparts store would carry them? | ||

I get my NGK plugs from NAPA, its the only place that always has them in stock. | ||
| Moosestang |
What's the part number for those NGK's? I have a napa right up the road. They are kinda a mom&pop napa, so they might not have them. | ||

Spark Plug: Iridium Part No.: DCPR8EIX Stock No.: 6546 | ||

I found the part number doing a search. DPR9 EIX-9 My local Napa doesn't have them and they'd have to charge me freight to order them. | ||

Spark Plug: Iridium Part No.: DCPR8EIX Stock No.: 6546 I thought it was DCPR9? I have the race ecm and drummer if it matters. I've seen both part numbers used in past posts and the 8 is supposed to be hotter than the 9, but which is correct? (Message edited by moosestang on October 03, 2008) | ||

NGK says DCPR7 is the correct plug, WTF! | ||

I'm needing some myself. I pulled this from American Sport Bike. 5889, 5887 - Spark Plugs 98-08 Spark Plugs for Tube frame and XB series. Does NOT fit 1125R. 5889 is NGK equivalent of the 10R12 Buell heat range plug, 5887 for long life NGK Iridium electrodes. These are the right heat range 9 plugs to be used on Thunderstorm and XB head engines. Heat range 8 is recommended for 95-97 engines. The spark plugs are priced EACH, order two if you have a twin, one if you have a Blast. Note: 5887 and 5889 are American Sport Bike part numbers, they are NOT NGK numbers. | ||

On NGK's website when searching by Make/Model, the plugs offered only range from 2002-2005 for the XB. Go with Al...prices are competitive and he will send you the right plugs. | ||

Firebolt- you are quoting an accurate assessment. Here's a link to NGK: http://ngk.com/results_cross.asp?pid=10r12a&seenCr ossWarning=1 The DPR9EA-9 is their equivalent to the recommended 10r12a plug- and a heat range of 9. I've posted on this before, but heat ranges are often mis-understood. A lower heat range means that the plug will operate hotter- the tip of the plug heats up more, and that it dissipates heat less. A plug needs to operate at the right temp, and needs to remove the correct amount of heat from the combustion chamber. Likewise, a higher number means a colder plug and a plug that has a cooler running tip and dissipates more heat from the combustion chamber and into the engines cooling system. NGK has a great read on it that is very informative: http://www.ngksparkplugs.com/techinfo/spark_plugs/ techtips.asp | ||

9 is the heat range. Pre T-storm or XB should (all 95-97, some 98) use heat range 8, all T-storm should use heat range 9. I found this posted by Al. Unfortunately Al will probably charge me $15 to ship a $9 plug, so I'm going to try and find them locally or just order them from a local place. So do the NGK's not come with the screw on terminal on the top of the plug? I've read that in several posts and I just don't see why they would sell a plug like that. | ||

"9 is the heat range. Pre T-storm or XB should (all 95-97, some 98) use heat range 8, all T-storm should use heat range 9." Correct. I have a set of NGK Iridiums- can with a normal snap in top. Worked great. | ||
| Firebolt32 |
The first post is simply copy and pasted direct from Al's website. I remember your posts about the plugs. This is where I pulled 10r12 number. http://www.americansportbike.com/shoponline/ccp0-p rodshow/5889.html Don't shoot...I'm just the messenger. | ||

Well I gave advanced discount autoparts the 5545 stock number from NGK's website (Napa also gave me that stock number). They said they were $5.99 each and would take a couple days to get in. Now i'm not sure they are ordering the right plug. That seems to cheap, but he said they are an iridium plug. Napa was telling me $9.19 each. I'm going to be pissed off if they aren't the correct part number. | ||
| Andymnelson |
"Don't shoot...I'm just the messenger. " Haha- no shooting, I was confirming that your info was correct :-p re-read it... | ||
| Moosestang |
Looking on NGK's website, they show that plug for a few different lamborgini models from the 80's to the early 90's. There picture of the plug shows it with no cap. Hopefully the cap is a standard fit because I have lots of old spark plugs laying around. | ||

I purchased the NGK iridium's from O'rielys last week 6 bucks each. Across the street at advance auto they were twice the price. I had to order them but they were there the next day. Also I put them in my 09 xb12ss and I noticed a difference right away bellow 3000rpm not as much stumble and a much smoother idle. | ||

Clarification on Heat Range numbers: Different manufacturers use different formats -- some have higher numbers are hotter plugs, others have lower numbers as hotter plugs. And, each mfg. may have a different temperature range. Advice: look on the mfg website as to which Plug to get. Dennis Kirk typically has what you need in stock as well for very good prices. I highly recommend NGK. Advice, part 2: plugs are so cheap that you should purchase the recommended heat range and then a set cooler. Run the cooler plugs in the summer and the warmer plugs in the winter. | ||

FYI, the NGK Iridium 9-series are also used in some Aprilia and Duc bikes as stock. i've picked up DCPR9EIX plugs from a local Aprilia dealer before, dont remember price though. | ||
| Moosestang |
I pulled the stock plugs and they looked pretty good. I don't know why people say it's difficult. Took me all of 30 minutes to remove and reinstall both plugs. Here's a pic of the rear plug. I wire brushed both plugs and regapped them. I'm pretty sure the ones I ordered are not going to have a top cap on them. The ones for the Aprilia are stock number 2316 and part number DCPR9.

I purchased the 2316 part number (DCPR9EIX). They had the top caps on them. http://www.oreillyauto.com/EW3/ProductDetail.do?id =1412641054&line=NGK&itemNumber=2316&exactItemNumb erIndex=1&didSearchFor=2316&bid=1223069689555&cycl eCount=1472¤tPage=0 http://www.partsamerica.com/ProductDetail.aspx?Mfr Code=NGK&MfrPartNumber=2316 | ||
| Moosestang |
Thanks big b. I called them back and advanced discount auto can't even get the 2316 plugs so i'm going to try to use a cap off an autolight plug on the 5545 ones. I was just trying to avoid having to order them online. The only difference between the 2316 and 5545 is the gap and top cap. Did you regap those plugs? According to NGK they are gapped to .028. | ||
| Moosestang |
Well that's not happening! My autolites don't have screw off terminals. I guess I'll ride around at lunch tomorrow and check all the auto part stores, as well as the two motorcycle stores, for the 2316 part number. If I can't find them, then i'll order them from Oreilly's. Maybe napa sells spark plug terminal nuts, who knows. Do not order the 5545 or DPR9 plugs. Order 2316 or DCPR9 (Message edited by moosestang on October 03, 2008) | ||

got mine from American Sport Bike, fast and perfect. If you need filters and the like that could help spread out the shipping. Though I had to gap mine....they were about .030". | ||
| Moosestang |
Just to let everyone know, I ordered the 2316 NGK's from sparkplugs.com. I figured I,d go ahead and order a new O2 sensor as well, but I see that they are pretty common. No one I talked to locally could or would even order the 2316#. I figured for the price of the 5545 plugs for discount auto, i'd just order the plug terminals from sparkplugs.com (.10 cents each)and use them as a spare set or my next set. | ||

Hey, just to feed your paranoia, is that the after picture because it looks a little lean? In reality, it looks like it's well within range. Why are you wanting to change it? | ||
| Moosestang |
that's before I cleaned it. I have over 8,000 miles on the stock plugs, that's why i'm looking for new ones. | ||
| Firebolt32 |
I bought two 10r12APP's from the dealership Sat. My original plugs look good as well. Since I have them both out I'm just going to replace them. Moose...I can get you these plugs for $12 for both. | ||

Denso Iridium IXU27 if you can find them. I am thinking about trying IXU27 in the rear cylinder and IXU24 in the front cylinder. Anyone try different heat range plugs between the front and rear cylinders? | ||

There picture of the plug shows it with no cap. Hopefully the cap is a standard fit because I have lots of old spark plugs laying around. The DCPR9-EIX9 has a screw on cap, and the DPR9-EIX9 does not, so make sure you order the one with the C (cap) in the part number. They also do a platinum (DCPR9-VX9) and a 'normal' (DCPR9-EA9) type electrode using the same first part of the part number (DCPR9). So long as you get plugs with this on you will have the correct ones for the XB. The Iridium plugs are the most expensive of the three but definitely the best ones to go for though. They last much longer than stock plugs, resist fouling far better and help reduce pinging (probably because they have a stronger and more consistent spark?). I Have read that silver plugs such as Nology are even better, but have never tried them so can't say one way or another. | ||
