I say we secretly drain his coolant and replace it with...Autozone coolant and tap water! Then, let's replace whatever new-ish random nuts and bolts he just installed with hand-tightened, heavily used nuts and bolts! Last, we should top off his oil with non-BMW, non-synthetic off-brand oil!

I had a better idea a few years back!

http://forum.e46fanatics.com/showpos...0&postcount=10

I will however say:

When i was alot younger with my 330ci um..ten -eleven years ago. I had made a heatshield for my first 50$ ebay intake with cardboard box and aluminum foil. I drove it up and down the mountain and i swear the intake and its "charge pipe" was def much cooler to the touch(cooler IAT ). One day from tinkering with it so muchl I had forgotten to clamp the the intake on the maf and it sucked in a small sheet of foil (which was torn to shreds by the metal maf grate). No damage was done(i think as it drove fine many years after even with a supercharger), but looking back i see alot of myself in these homemade mods, as wack and dumb as it may be its definitely constant thought and love for the car. A true fanatic.

I definitely did some dumb things in my young kid honda modding days. though its more dangerous to do to these expensive-to-repair german cars than a civic. young people don't understand the extremely high level of depth that goes into the design of modern cars and especially these cars in particular. no homemade part tinkering is necessary or advantageous. concentrate on your skill as a driver and getting to know your car

+10 on Mango's post. I'll add. If I saw that on a for-sale used E46, I'd walk. But take my post w/ a grain of salt, cause I simply believe BMW put the best in research & engineering, & they would have added that if it would need it, even back in the early 2000's.

Bend it in a brake, see how it works. Make it look as stock as possible. Report back with the results.

He means (I think) that every item of performance has been thought through and designed by a large team of engineers, and some kid just out of high school or college does not have the experience and understanding to improve the performance without a large outlay of cash to the people that know what they are doing.

I use this Craigslist ad for reference:

man... I really made an impression on you with my hood huh?
It seems to come up often .
BTW I also made my own "hood scoops" lol, actually they're known as air intake scoops. Check out my page if you want see it; even have a thread on it. Mine was made out of aluminum.
Irish, you know I would make it rather than pay RPI over $100 for it.
Cost me about $6.

Every time I see a Mustang with that hood scoop, I think of you. You should feel remorse for that.

I understand what Mango was trying to say. I wouldn't mess with BMW engineering either (for the most part).

"High level of Depth" just came across as a bit amusing, like: "Jumbo Shrimp" or "Army Intelligence" or "Rap Artist".

Having seen this "scoop" applied, I can only say that it's stupid.

The area in front of the radiator is sealed off so that it builds up pressure with the speed of the car. It's a plenum, of sorts, that's used to feed air to the intake and the radiator(s). The engine will only take as much air as the cylinders will let in. The pressure at the intake is a function of the velocity of the car. Nothing else matters. Adding this scoop doesn't increase this pressure. It just adds drag to the system.

The only purpose of this scoop is to take money out of your pocket and put it in someone else's pocket.



Which, btw, is why CAIs don't give the performance you would expect. You take the intake out of this high pressure zone and stick it in a wheel well where the pressure doesn't build with speed.
