He wants to cold air intake his car..... duh.


Not sure if he wants to move to Alaska, use his car as a cold air intake for another car or install a air induction filter in a "less hot" location.

I like your options...and how could you get it colder than from behind the bumper?

@bigd503
the E38's air box pulls cold air from outside of the engine bay. You can simple use a performance drop-in filter such as K&N, or if you prefer a cone filter, companies like Dinan make kits. You can also find cheap ones on ebay. Whichever route you take, you must prevent the hot engine bay air from reaching the cone filter or you could end up losing HP.
If you plan to make this a DIY, at a minimum, you will need a High quality cone filter, hose clamps, 3-4" mandrel bent tubing for the intake piping, and 3-4" silicone hose for coupling pipes to MAF and throttle body.

There have been plenty of discusssions on this subject in the past, and most people agree that the the stock system is pretty good. I fail to see why you would replace the existing ducting which draws cold air from behind the bumper with a different ducting? Any kind of filter that requires oiling to retain dust, has the potential to bugger up the MAF. If there is a claim that a cone filter allows more air through,how is that achieved? It has to be because the filter has a coarser mesh, and that in turn allows larger dust particles into your engine- do you really want that? Stock is good, leave well alone

re:

Chrisn7 has it right you do not need to CAI this car unless you are doing more, for instance buying a Dinan CAI along withe their MAF and throttle body and software then you will see some real performance but just a CAI is wasting your time there are U-tube vids that show performance difference with and without CAI on a Dyno and there is virtually no difference at all ........
