checking air filters - davidkerryedwards - 12-15-2006 04:25
How do people test their air filters? My European Mercedes motorhome had a
nifty feature.
It had a vacuum operated piston in the intake. When the air filter go dirty and
vacuum
increased in the intake, it would suck the piston down and it would show red in
a little
window. I see my intake, pre-turbo has a schrader valve (inoperable) in it
which I assume is
for testing with a vacuum gauge. Do other people have that? If not, what are
the options?
With filters at $80 it's nice to have a test before replacing.

Ok, I found one. I'll probably get it and install it in the intake.

Picked up my air filter indicator yesterday. Overpriced at $38 but still a good
way to keep
track of the condition of the filter. It goes in the intake between the filter
and turbo or
filter and engine intake. It's basically a vacuum guage that shows highest
vacuum pulled.
It should help avoid the problem Julia had with a plugged filter. It comes in
two versions.
On is threaded and the other fits into a grommet that itself fits into an 11/16
hole drilled
in the intake.
