E36 Mishimoto Silicone Intake Boot (Euro/540/Porsche 3.5" HFM)

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.

1995-1999 E36 M3 3.0 & 3.2 (with ASC delete)
