Silicon intake boot

[Sajk]

Does anybody know who makes a boot that fits our cars? I believe the e46 m3 one does not fit.

You can still get them from BMW?

Check the part number on realoem.com it will confirm what it fits.

Thanks guys. Looking for a silicon one.

@j3nks79 that Mishimoto link you posted seems to be for e46 m3 not a z4m? Are you sure it fits?

I can’t see why it wouldn’t.
Maybe message the seller to confirm

Rogue Engineering just released one, mine is on order.

The e46 m3 one does NOT fit the z4m as ours has an extra hose/connector.

And the Z4M intake elbow is more like a right angle, whereas, the one for the M3 has a wider angle.

I’d be surprised if this made a real difference on non-turbo cars. In “theory” it helps with flow but I doubt it makes any real world difference.

Maybe it's just to replace an expensive OE BMW pipe that splits?

The theory makes sense to me which is why I am interested in trying it but the cynic in me says no way power is left on the table for what would be a cheap part at scale. So i dont believe turner and bimmerworld claims of 7 to 10 hp or whatever. Also some additional vibration must be transfered vs the rubber flex pipe.

How many times have you seen the oe s54 pipe split?

Only once on mine. But I replaced it with an OE one

Did look for a full Samco kit when I did my cooling system refresh many years back, but there wasn’t an off-the-shelf kit available, so I didn’t bother.

I stand corrected then. What was the root cause?

Don't know.

Just had a small air leak causing poor running. Replaced the MAF but it didn't solve it, but then got told there was a tiny split in the tube, so had that replaced too. Of course, it could have just been a poorly fitted pipe (or the clamps being on cock-eyed), but it worked fine after that.

Maybe it was age, maybe it was the ham-fisted owner who kept swapping around various intakes for fun
