BimmerWorld Silicone Throttle Body Boot - E36/Z3

The 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 a result.

We 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.

Two versions available:

• Standard Fitment - fits with intake system utilizing stock mass air meter
• Euro HFM Fitment - for use with 3.5" mass air meter - extended tube length on HFM end allows installer to trim for a perfect fit for your specific intake system.  Much smoother transition for airflow than other add-in reducers.

Fits 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.
