i recently bought a 1999 econoline and notice the fresh air intake
snorkel is missing, is this part really needed. i don't know why it
was taken off. some people tell me force cool air into the thottle
body makes for better gas mileage, others say theirs no differances.

The air silencer forward of the air filter? Some think that removing the
restriction allows for better air flow and more horsepower with the
downside of more noise. The data I've seen with mustangs has been from
slight improvement in HP to slight loss of HP.

Without it your drawing in HOT air from around the engine instead of the
colder air from the front of the vehicle. It also quiets the intake
noise as well.

I know that those 'snorkels' and fresh air scoops are really good at
ingesting water in some vehicles. Some Jeeps for instance have/had them
just below the headlight on top of the bumper line so any water that got
splashed over the bumper from a puddle or creek gets instantly sucked
into the engine which can be pretty bad news. The engine hydrolocks
which normally destroys it.
Jeep stopped putting the hose on them for this reason but left the rest
of the parts in place. We now check every one before allowing them to
follow on a wet trail on organized trips.
