Fitment: E36 M3 3.0 and 3.2 Evo (non USA S50)
The E36 M3 Eventuri Intake has been meticulously developed to optimize airflow efficiency while maintaining low intake temperatures. Central to the design is our patented Venturi housing, which integrates directly with the MAF tube. This integration removes unnecessary junctions and establishes a continuous, laminar flow path from the filter to the M3’s intake plenum.
Where conventional cuboid airboxes and generic aftermarket systems generate turbulence and pressure losses, the Eventuri system maintains consistent velocity and pressure, maximizing volumetric efficiency. Intake temperatures are stabilized through thermal shielding and direct alignment with the OEM cold air feed.
The outcome is a marked improvement in throttle response and mid-range torque, along with sustained power delivery across the rev band—achieving performance gains without compromising drivability.
The Eventuri E36 M3 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
- Carbon Fiber Venturi Housing with Integrated MAF Tube
- Bespoke High Flow Generation 2 Filters
- Aluminium Inlet Cowl
- CNC Machined Hardware and Stainless Steel Brackets
- Breather Filter Set
Intake Housing Assembly
The filter housing comprises of our bespoke generation 2 filter, aluminium inlet cowl, the carbon pod with shielding and integrated MAF tube. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the plenum. This is a key feature of the intake design where we have removed the tortuous flow path of the OEM airbox and therefore reduced the pressure loss through the whole system. The MAF sensor connection has been relocated to be less visually obtrusive but still functions in the same parameters as the OEM system. Finally the housing has heat shielding around the filter opening to prevent heated engine bay air from entering the filter and therefore keeping IATs controlled.
Patented Technology
Our patented filter housings have a smooth reduction in cross sectional area as they shroud the filters and taper down to the tubing. This geometry invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patented design and a regular intake system. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings. Further details can be read in the Technology and Filters pages.
