ECIS E46 Intake? Any advice.

Hi Guys,

Considering replacing my ben fer intake with an ECIS unit. Does anyone have any input about the ECIS piece? Does my Xenon lights or any mounts need to be relocated?

Is the ECIS better than the Ben Fer unit?

The ECIS unit fits great, regardless of xenons (at least it didn't matter with my '02 330i). It sounds great (except for a slight whistle in low rpms) and is a great value. Get it!

It has good high speed sound, but the hissing at low rpms sux

I have yet to come across any aftermarket intake system that doesn't have that hissing sound. It's a result of the filter being exposed.

I have the ECIS system and can't complain one bit about it. Fit is superb and love the custom colour shield.

Actually Tom, it is 'wind shear' on the throttle plate (opening plate in throttle body) that causes that whistle at about 2500 rpm's.

Just an FYI

Ahhhh. So is it safe to presume that the open element removed some of the sound insulation, thus resulting in noticing the sound that was already present?

partly, but there is so much more cfm (air) now, the change in throttle body (style, size, posistioning) on the E46 (vs. E36) has changed sound characteristics.

ECIS is a great intake....I love how it sounds above 4k rpms. It took me about 30 min to install also
