Mishimoto 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).

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 larger 3.5" size to replace the adapter and stock intake boot and delete ASC+T on E36 M3 and MZ3 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. And you don't need the HFM adapter used with most HFM kits. 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: 
1995-1999 E36 M3 3.0 & 3.2 (with ASC delete) 
1998-2000 MZ3 M Roadster/Coupe (S52 engine)

The Mishimoto N52 silicone intake boot is constructed of five layers of silicone with steel reinforcement rings for maximum durability. The steel reinforcement rings keep this hose from collapsing when under load, keeping your engine supplied with adequate airflow. The stock N52 intake boot has a resonator that BMW included to keep the N52 quiet. We tossed that resonator to the curb for a nice increase in engine and intake tone. This N52 intake boot fits with the stock airbox and single-stage or 3-stage intake manifolds. The silicone construction will provide you with long service life, and the Mishimoto Lifetime Warranty will make sure your intake boot is always leak free! WARNING! Prop 65 may apply to this product. Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1968) is a California law that applies to call companies selling products in California. Prop 65 requires any listed chemical present above very low levels that are known to cause cancer, birth defects, or other reproductive harm.
