Eventuri Carbon Fibre Intake System - BMW E46 M3

The Eventuri Carbon Fibre Intake System replaces the stock setup with a purpose built carbon housing and MAF tube to improve airflow and response. Designed for the E46 M3 S54 engine, it delivers smoother power delivery and measurable gains without ECU changes.

Key features & benefits

• Material: 100% prepreg carbon fibre housing and air scoop for strength and low heat transfer.
  
  

• Precision parts: CNC machined MAF tube and aluminium inlet cowling for exact fit.
  
  

• Flow design: Venturi style path and high flow filter to reduce turbulence and restriction.
  
  

• Heat control: Aluminum heat shields with neoprene lining reduce intake temps.
  
  

• Power gains: Typical increase 10 to 15 hp and 8 to 12 lb ft torque.
  
  

• Fitment: Works with factory ECU and MAF sensor for plug and play reliability.
  
  

Vehicle compatibility / Fitment

Fits BMW E46 M3 with S54 engine. Designed for stock or lightly modified cars that retain stock MAF and ECU mapping.

Installation information

Tools required: basic hand tools and torque wrench.
Estimated install time: 1 to 2 hours.
Professional fitment recommended if you are inexperienced. Installation guide available on request.

Performance gains / Why it is needed

The stock intake restricts flow and creates turbulence near the MAF. Eventuri’s larger, smooth flow path and precision MAF tube let the S54 breathe better. Expect sharper throttle, stronger midrange, and consistent power on road and track.

What is included in the kit

Prepreg carbon fibre intake housing, carbon air scoop with CNC aluminium collar, anodised aluminium inlet cowling, high flow filter, CNC MAF tube, 3 aluminium heat shields with neoprene lining, silicon coupler, BMW spec hose clamps.
