The fog light opening would be a decent way to do ram air, but there is the drawback of putting the intake opening so close to the ground where you are more likely to suck up water and hydrolock the engine. They make energency bipass values you can put in an intake tube to prevent that but your getting pretty complicated at that point.

It's wonder there isent some way to tap into the IAT and just read the temps from there. After all we all have a air temp sensor in our intakes anyhow.

I ran the dual intake to the fog light holes in my 2002 in Light/Heavy rain and never had any problems. Although I had afriend run the same setup on his in light drizzle and it was full of water.

Also the DIY intake looks great. A lot of guys use this method and are very pleased with the results.

Oh and for those that want a smooth pvc intake without the connectors can buy the thin pvc (most prefer 4") and can use a pvc heat blanket and heat it up so you can bent it how you want it.

To the OP, when you do your exhaust and if your on a budget the main thing you want to do is replace the y-pipe. The rest still flows decent. I ran the AT 30/30 for a while and loved it. Its a great muffler. Later I switched to the Aero stealth 170 for a more quieter muffler.

Looks great.

I saw a 1mpg around town 2mpg highway increase after doing mine.

I lost the gains back to where I was after installing my new muffler... Of course that could be due to me being heavier on the pedal just to hear the roar...

that looks pretty damn skippy for PVC. major props to you for creating which seems to be a decently effective CAI out of everyday products. true DIY just the way i like it it would be cool to see some numbers on the temp and power gains

if you have a muffler shop anywhere close they usually carry them all day. i stopped by my local monro (who by the way are idiots and quoted me $92 when i asked about a y-pipe, which they quoted me on a full exhaust) but i went thirty feet down the road stopped at Cole Muffler/Mavis Tire and in 2 minutes he got me a y-pipe told me they could form it to fit my duals diameter and length all for $44. guess who's getting my business

I don't know ago HP gains ... but I just got back from a trip up north and averaged 2mpg higher on the freeway than I had been driving the same freeway back and forth to work. I was carrying more weight and had my rack up with a luggage carrier on it (more wind resistance). If that 2mpg is from the CAI then it paid itself off on the trip.

Very interesting build. How do the couplers work as far as airflow restriction? I am sure it is "way" better than stock, but just curious. I would think that a smooth solid pipe would flow better.

Either way, great idea. I just wish that more companies would start to recognize the 4.7L owners and produce more.
