BMW Intake Boots & Hoses

The intake boot provides a pathway for air from the air flow sensor to the intake manifold. On most BMWs the boot is made of rubber with an accordian shape that allows the engine to shift and vibrate. As with any rubber component the rubber can dry out and crack and that can lead to serious running and drivability issues. A crack in the boot means that air is entering the engine that is not being monitored by the airflow sensor. The engine computer relies on data from the airflow sensor to set the fuel mixture in the engine. Excess unmetered air can result in lean condition faults, rough running, misfires, and other performance issues. For misfire and lean condition faults, check your intake boots first.

As an alternative to the original rubber, we also offer silicone boots that are both stronger and last longer with a 4-layer silicone design. Samco silicone boots can also decrease your BMW's intake turbulence and restriction by replacing the accordian design with a smoothed internal surface. Samco boots are also perfect as part of a kit to eliminate the factory traction control system (sometimes called an ASC delete boot).

The intake boot is a regular issue especially for BMW's, nearly all vehicles have a boot manufactured from rubber with an accordion section in the design for flexibility. This flexible section is typically where the failure comes from, leading to vacuum leak engine codes, rough idle, and increase fuel consumption.

When you upgrade to a Turner silicone intake boot you get a perfect fit that will not only outlast the OE design (meaning any vacuum leaks and rough idle), while also smoothing out airflow within the intake tract. This boot also eliminates the factory intake resonator giving your engine a much more aggressive sound under the hood especially at higher rpm. Available in black or Turner blue color, our intake boot offers either a pop of color or a cohesive, complementary look in your engine bay.

The Turner Motorsport silicone intake boot is manufactured with 5 layers of wire reinforced silicone to prevent collapse under load. Engineered in-house utilizing 3D scanning technology, this boot offers perfect fitment with the factory air box and either single stage or three stage (high output N52) intake manifolds.

Install as a standalone reliability improvement or in addition to our three stage intake manifold and Turner performance tune (available here).

Replaces OE intake boot 13717536004.

Features:

  • 5 layers of wire reinforced silicone
  • Perfect fitment with factory airbox
  • Compatible with single stage or three stage manifold
  • Installation hardware included

It also works great as a coolant hose plug. The diameter of the tip is 20mm (just over 3/4"). A low profile Oetker compression clamp is included. The plug can be drilled and tapped for a small air temp/water temp sensor, pre throttle body vacuum/boost/MAP sensor barb, or water alcohol/nitrous/methanol injector or barb. Works with M50, M50TU S52, M52, S52 throttle boots and may work in other applications with a 20mm hose.

A silicone intake boot offers many advantages over the stock accordion-style boot:

  • perfectly smooth interior surface (less turbulent air)
  • stronger and more durable (no rips to create vaccum leaks)
  • will not attract or radiate heat to the engine bay

This intake boot is the stock 3.0" size to replace the stock intake boot and delete ASC+T on E36 and Z3 models. Normally deleting ASC will require a new boot from a non-ASC model but this boot is stronger with a small power gain as a bonus. The Mishimoto E36 boot has a perfectly smooth interior finish with no sharp angles or other obstacles for the intake air to be slowed by. Installing this boot assumes your car either does not have traction control (ASC), or you will be removing it from your car. Removing ASC is a great way to decrease intake restriction, and this intake boot is perfect for this upgrade.

This boot has two ports to work on early and late E36 models. Early cars have vaccum and the crankcase vent hoses entering the intake boot. Later models only have the vaccum hose (the crankcase vent empties into the oil dipstick. We offer an intake boot plug for the later models to plug one of these holes. You can add one from the options below.

Choose from black, blue, or red silicone.

This Mishimoto silicone intake boot fits the following BMWs:
1992-1995 E36 3 Series 325i, 325is & 325ic
1996-1999 E36 3 Series 328i, 328is & 328ic (with ASC delete)
1995-1999 E36 M3 3.0 & 3.2 (with ASC delete)
1997-1999 Z3 Roadster/Coupe 2.3 & 2.8 liter
