RE: Homemade cold air intake
Fitting that an aero guy would be named Breeze. I have had several beers while staring at the engine compartment and thinking of ways this could be done. You figure if it works for theCraftsman/Busch/Cup rides with the angle of thier windshield, it would work even better on ours. The only problem is that they stuff the engine so far back in the compartment that the tb ends up under the cowl. It would almost have to entail a 180* bend, thereby 'stacking' the duct. Given the limited room between the top of the tb and the hood, this would severely limit the size (thickness) of the duct. The way I see it, the only way to compensate for this would be eithertogo wider where you would run into support issues, or to get a hood designed to accomodate cowl induction. Have you come up with any ideas?

RE: Homemade cold air intake
I have been wanting to do this to my V10 version for awile, been busy. I want to take this a little further. I want to stage my intake filter and place it into a large rectangular slot in the bumper's covering. Ther actually 2 of these open rectangular slots on the trucks front bumper. I n the middle center of the bumper.. I plan route my duct to that location, and fabricate a wind catch behind my cone filter (like a win funnell/at highr speeds. This way it'sdesign captures forced air into the ducted cone. When I do my duct work, I want the inside to be smooth bored, and 9harder to seeno bends are more then 22 degrees. From the front, will see little traces of the come filter. We will black inside rectangularc cover to conceal. With the wind shroud around the cone filter will be like a huge funel ramming trapped in into the intake. There could be some points gain or lost with this thought. But one worth trying out. Could you imagine the performance gain with a modest PSI gain on the intake at high speeds? GP
i rout this.
I was on a happy sleepy bill when callled Ambien. excuss the speeling and wording,

RE: Homemade cold air intake
I am using the Ram Air Box right now. It makes a big difference and is a good setup both power and mpg wise.

My only complaint is that it takes up to much room in the engine compartment and has to be removed to do the slightest bitof maintenance. It would be nice to come up with something that took up about the same amount of room as an open filter while still supplying cool air and positive pressure to the intake manifold short of buying a new hood.
I just redid my exhaust, so I can't say whether it is that or the Ram Air Box, but I am getting ~16.5 mpg HWY cruising 74-79 mph. That with the mods listed below. Around town it goes down to 11.That, I think mostly,because I can't stop driving like a teenager.

Home Brewed Cold Air Intake
I just finished doing my homemade CAI. Took me a while Since I'm REAL particular about my truck and what goes in it like most of you out there. It looks pretty SWEET!!! What I did is I took the air hat off a 96 Jeep grand cherokee (with a 5.2L Magnum engine). I bought a 3/4 inch carb spacer and a 15 foot roll of 2 inch wide exhaust wrap from Summit (I love Summit. Jegs screwed me over and left a bad tast in my mouth). Then I went to the Home Depot and bought a 2 foot sectioin of 4 inch heater duct (the kind that comes in a flat sheet and you roll yourself) and a 2 inch wide metal pipe clamp with rubber sleeve. I cut mine so the pipe is 3 and 1/2 inches wide. I topped it of with a dual cone 3.5 inch air filter. Money WELL spent. It looks similar to K&N's FIPK. in total, it cost me about 40 bucks. I'm just finishing it off now by putting a heat barrier to promote more cold air. If anyone's intrested I'll be more then happy to give details and pics. I mainly wanted to emulate K&N's FIPK...I got pretty damn close to the real thing.

Hey, hope these pics came out good. I took them with my phone. I still have to put the heat shield up. I'll get to it this weekend. I'll be sure to post a pic of it completed.
