Air filter for off road
Greetings!
I have a 78 F150/460 with a stock air filter and housing. I don't think the Holley 750 can "breathe" enough, so I want to open things up a little. I do plan to drive it mainly off-road, but I don't want to spent the $$$ for the K&N system. Is there any real danger with those chrome top/bottom covers and an open filter? I would think the olny threat would be water. Any insight would be greatly appreciated.
Thanks!

Kevin,
Can't say I know much about your truck or the engine or anything but I might be able to help. Some people will actually take a replacement K&N air filter, put it in the air filter housing, but before doing so, they cut away a lot of the housing so more air can get sucked in. This wouldn't be a true cold air intake but it will assist in bringing more air into the engine. Hope this helps. Goodluck.

Kevin, there are gobs of cheap K&N's on E-Bay. I found one for my Bronco there last summer. If you use an oiled filer off-road in dusty conditions, you should also use a pre-filter wrapped around it. A cheap and effective trick for this is to cut out sections of panty hose and wrap around the filter.

Thanks for the suggestions! I have a spare air cleaner housing that I can mess around with. I'll check ebay as well.
What about punching thru the firewall and getting your air from in the cab? Wouldn't that be cleaner air? It should eliminate most of the dust and all the water.
Any thoughts?

Just a thought but the firewall is a FIREWALL, keeps unwanted fumes, dirt ,dust and most of all FIRE from getting into the cab.
Doesn't take much for a fire to happen, better safe than a crispy critter.

in my recent four wheel and off road magazine they featured a truck that had a snorkle that ran into the cab. it ran through the fire wall and out the glove box to the ceiling.

I guess I should've been more clear. I do plan to run a duct through the hole in the fire wall. I was planning on putting the intake opening either under the seat or under the dash. However, the glove box idea might be better.
Thanks for your input!
