Eventuri Carbon Fibre Intake Kit - BMW E46 M3

Performance increase = 10-15hp, 8-12ft-lb

The E46 M3 intake system is a result of extensive data logging, dyno testing and design optimisation. Our aim was to develop an intake system for the S54 engine which worked with the stock ECU map and MAF sensor and produced a genuine improvement in the driving experience.

Made from 100% pre-preg carbon fibre of the highest quality, the workmanship on the housing is second to none. This encapsulates the filter and is mated to an anodised aluminium inlet cowl to ensure a smooth inlet flow path. The filter itself is a deep pleated, high flow double cone configuration which is dry to avoid damaging the MAF sensor. Finally the assembly is then mated to an aluminium heat shield which effectively shrouds the intake from engine bay heat and captures the ambient air being diverted from the scoop. Also notice the rubber spacer on the mount of the heat shield - this is for the headlight module to sit on so that it remains at the right height - small details are important!

The MAF tube is CNC machined from aluminium and then anodised. The MAF boss itself is machined from an engineering plastic to minimise the heat soak into the sensor through conduction. We have incorporated a machined recess on one side to allow the OEM rubber gasket from the stock air box to be used for a perfect seal into the stock elbow.

The optional air scoop (pictures below) is 100% Pre-preg carbon fibre with a CNC machined collar - the air scoop forces ambient air directly into the filter opening. This scoop simply clicks into place in the front right hand brake duct and effectively saturates the mouth of the intake with cold air. It has been designed to take up half the height of the duct in order to allow airflow to still continue through the duct for the brakes. The scoop is so effective that even after a hard drive, the aluminium cowl at the mouth of the intake will still feel cold to touch!
