So,the "new" plugs got fouled,too. Not the plugs fault.

I've been running Platinum 2's in my '87 Accord for over a year now without a
problem of a need for a cleaning - last time I checked them, they still looked
near-new. *shrug*

I used Bosch Platinums in an '84 Nissan 300 ZX I had, and they worked great.
Good thing, too, because plug access was the pits. I tried the same style in
our '85 turbo Volvo (against the recommendations of thre Volvo gurus) and it
worked for a few months before the engine began to misfire. I removed the
plugs and saw there were only holes where there had been center electrodes
before. Huh.

the problem i've had with bosch, repeatedly, is that one day they work
fine, the next, the car won't start. you spend ages messing about
trying to get the things to work, but they won't. although widely
hated, i've had better luck with champion than bosch, even though
construction quality on bosch appears better.

ngk are by far the best way to go. especially when you consider that
there's no price differential. they continue to fire even, when the
electrodes are melted to little blobs. amazing things. no idea why,
but that seems to be the way it goes.

Agreed.

I've found that once Bosch plugs get wet, forgetaboutit...

When I owned my first car, a 1940 Chevy back way back, Champions would
begin to break down after 5K miles especially when going up hills.
Family mechanic warned against Champions so switched to AC and no more problems.

Champions (and probably Bosch) are good to fill the sparkplug holes for
storage so that the mud dawbahs don't build nests...

That was my experience in the '70s - misfire under load after a few months.
I stopped using Champions and haven't seen fit to give them another chance.
