Read somewhere about useing a longer air intake tube and mounting it
under vechicle facing forward incomming air, this is supposed to due 2
things..

1. assure intake air in not being heated by any engine componets
therefore giving better mpg/hp

2. force of air entering tube creates more pressure allowing more air
to enter filter canister and thus into intake manifold itself

I have no idea if there is any true to this method or if it actually
works and would like to get opinions on this...

Thanks.

also if anybody knows any good links to web sites with info on stuff
like this that would be great to

3) Goes through more tubing, increasing resistance.

4) Is closer to the ground, where more dust and dirt can be picked up.

5) Is closer to the ground where more water can be picked up. Especially
handy when going through deep puddles.

Not only would doing this be a PIA, because you have to find a way for the
hose to get down there, you're going to get more air and water into your
engine.

It sounds like you are doing a lot of work that can harm your engine.

You are describing ram air. This was popular some years ago and the
hood scoop really looked sharp on the little boy sh.t box cars. The
idea was that the faster you went the more ram air you got and a
'measurable' boost in power . What you really got was an air filter
that clogged sooner with bugs and road dirt in the summer. In the
rain you literally drowned your engine. It the winter it got
plugged with snow and ice and that crap that's laid down for ice
suppression - sand and salt. I knew some people who put the scoop
on with wing nuts so that they could turn the scoop backwards for bad
weather driving. That really looked sharp when driving in reverse.

Possible if intake pipe is too short ( like Nissan Sunny 120 & 130Y ).

Agree

| any good links to web sites with info on stuff like this

Just curious, wouldn't car manufacturers want to meet epa requirements
for better mpg, and have built the best already?

I understand doing things like upgrading the air filter, etc, but
moving a whole intake? Little Help?
