Also, not having it meet a sealed opening on the front of the car lowers the risk for vacuuming up large amounts of WATER! I used PVC about 2 years ago and it still looks good. I also cleaned up some of the tabs on the inside of the box and painted the whole thing in Ceramic paint... The best part is the suction noise it creates, AWESOME! Along with the Shark Injector, some very noticeable gains.
great minds think alike lol

Water + Intake = Explosion. Seen an engine that had a piston go though the side of the block and damage other components at one of my mechanics shops. He said it was because the engine sucked in water. I don't know how factual this is, but it makes me afraid to do anything more than the K&N CAI and water sock to my intake.

From Wiki:
Quote:
Hydrolock (short for either hydraulic lock or hydrostatic lock) is a condition of an internal combustion engine in which an incompressible liquid has been introduced into its cylinder(s), resulting in the immobilization of the engine's pistons. The liquid causing this malfunction is often water, hence the prefix "hydro-". Hydrolock occurs in a 4-stroke engine when liquid is sucked into the engine's cylinder(s) during the intake stroke and, due to the incompressibility of the liquid, makes the compression stroke impossible. This, in turn, prevents the entire engine from turning, and can cause significant engine damage if one attempts to forcibly turn over or start the engine. Typically, connecting rods will be bent, making the engine uneconomical to repair.
You guys should definitely be careful with this mod, also search google for hydrolock, it isn't pretty.

Here's one thread from a corvette forum:

Yup. I've said it once and I'll say it again. The portion of BMW's R&D department dedicated to developing the airbox has a larger budget than any aftermarket supplier out there. The answer is not always "cone filter + heat shield".

As far as I recall I don't have a fan in front of my radiator, so I can just install this duct system (DIY of course) right up to the kidneys.

Here's what I'm thinking:


DIY the stuff circled in red. Either made of metal, plastic or custom made CF
The turquoise would be where the MAF is positioned.

Now for us 323/328 owners: We can get gains by installing an M54B30 intake manifold, and they are not minimal either, as far as I've heard. Good part: THAT'S STILL POSSIBLE by going with the frontal RAM intake DIY.
I know its a old post but I can see this overheating since it covers almost all the radiator.
