Steve,

IMHO...

1.>  Long-life is better than the Lowtox.  The orange stuff.

2.>  I have a Bentley and feel that it is adequate.  Ron Salmon imported a few
Haynes manuals from GB a year or so ago.  He might still have them.  (http://www.busdepot.com)

3.>  I've used K&N air filters on my bikes for years.  Also used them on my
Baja bug.  Four times as expensive as a throw-away, but then if you wash it
five times then you're making money.  FWIW, use Simple Green to wash it and
re-oil with the correct K&N oil.  Comes in a spray can available at your local
motorcycle shop.  Never gotten around to putting one in the buses but seeing
that the only failure I've ever experienced with one was heat related, I have
no reason to believe that it wouldn't last forever. They claim better
filtration too.

Lastly,  Welcome to the list!
