    They might well be but they are designing a unrestricted air intake... So the ECU is restricted so what not to say the intake box is...

    I am a fan of the OEM system purely because I like my car and want to protect it from unnessecary damage, I understand why people want to go down the CAI, Panel filter, cone Filter, oiled (or Not!) type route (and have in the past tried most).

    Think you will find that the BMW OEM systems are "Fit for Purpose!" and if you look at the M3, or an EVEN Better M3 CSL they effectively increase the volume of properly filtered air available when demanded.

    The CAI in principle is scientifically correct, but claims from the filter manufacturers are somewhat "economical with the truth!" and a long pipe with large angled bends in it is not at all going to be a plus point. An Oiled filter needs to be periodically Re-Oiled! Why? Is it because the oil has evaporated? Or is it because over a long period of time oil molecules are sucked into the intake (potentially causing dirty MAF?)?

    BUT THE CAI SOUNDS GOOD!!

    I know the E36 intake is restricted and me putting a cone filter on it has done it the world of good!

    Not so sure on this system though... Reminds me of halfords of the USA...

    Here are all the reason BMW engineers will not use a CAI in their cars.
    1) Sound - the excessive noise offsets them to put one in.
    2) Cost - does a stock BMW come with O.Z. rims? i don't think so. a standard paper filter is much more cost efficient.
    3) Convenience - you can get your filter changed easily, but can you get it cleaned? Not unless you're willing to do it yourself and most people won't..

    Those can be taken further however those are the basic reasons a CAI is not a stock part of a car. The third being the most prominent reason. Now please bug off because i told you, i know what i'm talking about and i don't need some goof to try and discourage me.
