What intake options do we have for Z4M?

Eventuri is the way to go from a sound point of view. It's brilliant.

Having said that I have not experienced the AFE which has a much larger air filter. The only thing that worries me about the eventuri is the little simota air filter.

Yeh I thought that too, smaller filter element than the OE air box surely.
 
Eventuri say no need to oil. Simota say you can oil the filter in dusty areas so i plan to lightly oil the filter. My current filter on the intake is not oiled so when i take it out to cleas i will replace with an oiled one. I only hope its dirty when i remove it. Other aftermarket filters i have used never seem to get dirty which means the dirt goes straight through.
 
I had an aFe intake for many years and it made a great sound. It was loud enough under load to sound really purposeful, but not enough to drown out my Remus back boxes. This intake / exhaust combination added bass to the S54 intake rasp and treble to the screaming exhaust at 8k rpm with plenty of pops and bangs on the overrun once the exhaust was hot.
Unfortunately, the heat shields around the cone filter started to corrode under the powder coating, so I decided to replace it. I now have a GruppeM which looks far better than the aFe heat shields, but the sound is a little anaemic in comparison. I’m a somewhat disappointed because the GruppeM on my RS4 sounds incredible. Interestingly, I’ve had no MAF issues with either intake on my Zed but my RS4 needed a remap to prevent very occasional check engine lights (it’s now running at c. 450bhp, so it was worthwhile).
If you want great induction sound for a relatively small outlay, I’d recommend the aFe intake. If it’s under bonnet pornography your seeking, then the GruppeM fits the bill. If you want both and can justify the expense, a CSL-style air box is the best of both worlds.
 
^^^^^What he said about the AFE unit. :lol: Ours is coupled to a Saclam titanium exhaust system from Japan.

Nicely done! A couple of caveat, though.
1. Make sure whatever material that's used to print that MAF housing is able to withstand the engine bay heat.
2. The OE box has an "air straightener" screen for proper MAF reading. If your engine isn't running properly with this new setup, you may need to incorporate that screen into your MAF housing. For example, the aFe intake, which is a similar design requires you to transfer that screen over from the OE box.

1) yeh I figured this may be a problem, so will just monitor for any obvious deteriation.
2) hmmm, how annoying. Do we know if the screen can be removed from the OE box in a non-destructive way and be put back on later?

Pretty sure it's ONLY gunna suck warm air TBH.

If I recall, the screen is attached to the top half of the airbox and is held in by either 2 or 4 screws.

Great! Thanks for this. Will try tonight i f I can get baby to sleep in decent time.

I've been speaking to some other Beemer owners who have warned of A/F mixture warning lights after changing to aftermarket intakes. Fingers crossed the straightener will stop that.
 
I just realized that it's the Gruppe intake that requires you to transfer over that screen, not aFe! Brain is failing me :oops:

OK screen removed from OE and added to my weird mod. Luckily was pretty much direct fit. Fingers crossed all works well.

The eventuri filter has no screen, and it never gave me a check engine light nor a MAF code.

Roger, I thought I'd do it anyways, just incase.

I've had this car for 4 months now and haven;t driven her yet (new baby etc), 2 days until I get her tax/MOT/Insure and actually use it :)
 
I just ordered a Haiums airbox and can't wait to get it installed. As for the filter that comes with it, does anyone have experience running the ITG filter? Haimus state that it is washable.

No idea. But I am jealous.

OK so 5000ks since eventuri installed and time for annual oil change so put a new filter in and cleaned the old one. It was slightly discolored in the inside that faces the air flow with some insects. This worried me so I ran some white tissue paper inside the filter housing and inside the intake tube after the filter. No visible dust so I guess that's good. Having said that at 5k kilos I know an oem filter would have looked much dirtier.

Just to close this out.
 
Cleaned mine with the Simota kit for the first time last year - before that it had just been occasionally vacuumed - and immediately afterwards had a wandering throttle while cruising. This was fixed by resetting adaptations using INPA, presumably because a lot more air was suddenly getting through!

Gosh that thing was filthy. Did you check inside the maf tube? I purchased my intake second hand and it came with the old style filter like yours and it was also very dirty. Difference was that the inside of the carbon housing was also filthy. The older style filter that came with the intake seems, to me, to be significantly more porus than the new style. I never used the old one after I saw the inside of the housing. Glad it was the guy I bought it from and not not my s54 that chowed all that dirt. I don't know of it had ever been cleaned. Even had sticks in.
 
Ah, interesting. The whole plenum’s been off a few times and everything has stayed pretty clean, but I’ve only done about 4000 miles in the past 4 years. Carbon housing also fine.
