stock rubber intake boot on your BMW is a good functional piece,
but leaves power on the table. The bellows design creates flow
turbulence. Additionally, the common Euro HFM adaptor piece has
very abrupt transitions over a short length and disrupts airflow as
have found a silicone hose manufacturer made this intake boot to
our specifications, replacing the stock rubber boot. High quality
4-layer silicone construction will withstand anything you can throw
at it for years to come. No more dry-rotting rubber! Hp increases
from 3-8 Hp seen in testing from this piece.
all E36 3 Series with M50/52 6 cylinder motor, 1996-1998 Z3 6
cylinder, and 1996-2000 MZ3. Will not fit cars that retain factory
traction control (this boot will allow removal of this piece for
additional power gains). All hoses come with two breather ports and
plugs to cover them when not used due to your specific
configuration. Euro HFM not included. May require slight relocation
of charcoal canister.

I absolutely love this product! Fitment was spot on, and defintely noticed a difference in throttle response, I would highly recommend this product for anyone looking to replace their OEM boot. Excellent customer service and fast shipping too!!

Great product does what it's supposed to. Gives back that lost horse power from the old rubber one cracking.

great product and great price
good product, bad plugs
From Tyler Davis of RALEIGH, North Carolina on 2/22/2013.
So, as previous reviews have mentioned, there is some trimming required. The only issue I had is the plugs provided are too small. I used silicone to secure one of them in. If I just put it in there, it fell out as soon as I turned it over. Knocked off a star for this because I had to let it cure for a few hours, making it not nearly as quick of an installation as I'd hoped.Be sure to boil it if you're having trouble getting your MAF housing on.

My stock boot was old and the 2 ports on the bottom were cracked. This Beautiful silicone boot Fits and Looks Great.Keep in mind that this boot is for several models so some trimming may be required. Use a new razor blade with appropriate handle for a clean perfect cut.
