Designation Codes Chart with part numbers in link below. Seems to have at least some specs. I didn't see the 43xx numbers anywhere. Not sure my old version of Works is able to properly format the XLS file though. http://www.boschautoparts.com/NR/rdonlyres/C77B3446-232B-4AEC-AFA9-AD05F2A0A2AD/0/DesignationCodes.pdf More info here including a nice downloadable plug reading chart. Way better than the B&W pics in the first ignition book I bought. http://www.boschautoparts.com/Resources/TechnicalResources/ I've always preferred Champion. No one but Honda recommended NGK and ND makes plugs for my ST1100. At $7 a pop (Honda dealer or Internet after shipping) buying something cheaper at Wal-Mart sounds good. I lucked out couple of year ago and got a 10 pack for $20 at a end of season sale. Said they mismarked them but sold them anyway. Almost as irritating as having to make adapters from the old headlamp bulbs to keep from Paying Hondas exorbitant prices. Eicho makes them and shows them in their catalog but no one else sells them retail. AFAIK the bulbs are used in the ST, VFR and GW. Either Honda is controlling their sale or someone is missing an opportunity. $25 vs. ~$8 X2.

That was educational. I know what the Bosch equivalent of the NGK plugs in my Yamaha is, but I don't know if Bosch makes a platinum or iridium *motorcycle* spark plug. In order to use a plug that fits both cars and motorcycles, I have to be able to screw the end cap off. The Bosch equivalent of an NGK DP8EA-9 is WSR7E, and I would expect to find a WSR7E with a "P" suffix if Bosch makes a platinum version, but I don't. >http://www.boschautoparts.com/Resources/TechnicalResources/ The Bosch site is frustrating because it won't let me search for any vehicle except a car. > >I've always preferred Champion. No one but Honda recommended NGK and ND >makes plugs for my ST1100. NGK came out with copper core spark plugs thirty years ago, and the copper core is more heat stable than the old Champion steel core plugs. I could do about two or three full throttle runs with Champions installed and my Suzuki's engine would start shooting ducks (boom! boom!) out the exhaust, and that could be blamed on overheating the electrode, but, once the engine cooled down, the spark plugs were never the same, and performance was restored by going back to NGK's. Nippon Denso heat ranges are always three times what the NGK heat ranges are, so if I need an ND equivalent of an NGK "8" heat range, I look for an ND "24" heat range. Nippon Denso seems to have beaten NGK to the concept of expanding the flame kernel by having a U-shaped channel in the ground electrode, and that made the ND's "Hot-U" plugs operate like they were half a heat range hotter. Then NGK came out with the gold-palladium spark plug that was supposed to be like "a poor man's CDI" because the tips would get so hot they would burn clean. That didn't work so well on a two stroke because of the lubricating oil burning onto the insulator nose and shorting out the relatively low "high" voltage from the small ignition coils on Japanese motorcycles. >At $7 a pop (Honda dealer or Internet after shipping) buying something cheaper at Wal-Mart >sounds good.

I get annoyed when the $tealer$hip tries to charge me $2.50 for a copper core NGK plug. I remember when I could buy American-made spark plugs for $0.65 each, but that was 30 years ago. If you do have to pay $7.00 each for iridium or platinum plugs, the up side is that they will last three times as long. > >Almost as irritating as having to make adapters from the old headlamp bulbs >to keep from Paying Hondas exorbitant prices.

Either Honda is controlling their sale or >someone is missing an opportunity. $25 vs. ~$8 X2. There are two factors in the pricing of electrical/electronic parts. One is protectionist tariffs and the other is the fact that motorcycle distributors and $tealer$hip$ operate like drug dealers: the price of the part gets doubled at each point in the pyramidal operation. -- Message posted via MotorcycleKB.com http://www.motorcyclekb.com/Uwe/Forums.aspx/tech/200712/1
