Bosch Platinum Cross Reference?
Albrecht via MotorcycleKB.com
Choke and Carburetor Cleaner to soak my motorcycles in and I noticed they had
a lot of Bosch Platinum spark plugs for $8.88 a pair.
The Bosch part numbers are 4301, 4302, 4303, 4304, 4305, 4306, 4307, 4308,
and 4309.
If I knew what the NGK or Nippon Denso equivalent was, I might buy some Bosch
Platinum plugs.

It took 30 seconds on Google to find this.

But I haven't looked through it yet.

plugs.I could NOT find any platinum plugs that cross referenced for
motorcycles.Not saying there aren't any but I own Kawasaki Honda BMW and
Suzuki's and couldn't

I'd prefer someone else virus check the files too ;^)
Googling the website it probably legit.

I cba arsed to look. I d/l a massive (2.2MB?) Excel document: someone
else can look through it if they want.

Oh yeah, it's all a conspiracy theory. I blame Elvis.

It appears the numbers above are stock numbers not part numbers. 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.
More info here including a nice downloadable plug reading chart. Way better
than the B&W pics in the first ignition book I bought.

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.

Thanks. 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.

The Bosch site is frustrating because it won't let me search for any vehicle
except a car.

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.

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.

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.
