Looking to unlock the true potential of your BMW G42 M240i? Look no further than the Eventuri Performance Intake System. This meticulously engineered upgrade delivers the perfect combination of increased power, improved throttle response, and enhanced sound – all while maintaining optimal engine health.

Why choose Eventuri?

The stock BMW G42 M240i intake system has limitations. The restrictive design and proximity to the exhaust manifold lead to heat soak and reduced air intake volume. This translates to less power and compromised performance.

Cold Air Advantage: the sealed airbox with a gold reflective heat shield effectively minimises heat transfer from the exhaust, ensuring cooler intake air temperatures.
Maximised Airflow: utilising a secondary air feed and a larger, smoother carbon fibre intake tube for improved airflow and reduced restriction.
Enhanced Power Potential: Dyno-tested results (see our website) showcase the potential for increased horsepower gains thanks to the optimised airflow.
Superior Filtration: Our custom high-flow dry filter provides exceptional filtration efficiency with a larger filtration area compared to stock.

Crafted from the Finest Materials:

The Eventuri G42 B58 intake system is built using 100% pre-preg carbon fibre for exceptional strength and a smooth internal surface that optimises airflow. This meticulous attention to detail ensures peak performance and a truly premium look under your hood.

Dual Feed Carbon Fiber Airbox

Crafted from Prepreg Carbon Fiber, the airbox serves 2 objectives - to seal the filter against engine bay heat and to provide a dual cold air feed. Since the airbox is positioned next to the exhaust manifold it is crucial for the filter to be fully sealed so we designed the airbox to encapsulate the filter and at the same time provide a large internal volume. To seal the intake tube we have designed a laser cut plate with a rubber sealing strip which secures to the airbox. The intake tube passes through the plate and the rubber seal ensures heated air does not enter the airbox. To further minimise heat soak, there is an additional heat shield with a gold reflective layer on the exhaust manifold side which effectively combats the radiant heat transfer.

Having a fully sealed airbox results in the problem of having a restriction for the cold air feed. The stock airbox draws air from a single duct which extends to the front bumper area. During development we identified another area to draw cold air from which was a gap between the wheel arch and the chassis on which the airbox sits. To utilise this feed we extended a scoop at the back of our design which protrudes into the wheel arch and can even be seen after installation behind the front wheel. This second feed allows the turbo to draw from a larger area therefore reducing the restriction.

Carbon Inlet Tube

The G42 B58 OEM airbox system was updated in cars built after November 2018 where the airflow sensor was replaced with a temperature sensor in the inlet tube. Prior to this date, all airbox systems had an airflow sensor and for this reason we offer 2 variations. The V1 intake which has an inlet tube to take the MAF (airflow) sensor and the V2 intake for cars built after November 2018 which use a temperature sensor. The difference in the tubes can be see below.

The stock inlet tube has a flexible and convoluted section to provide movement with the engine. This however also adds the possibility of turbulence in the flow path as there are multiple faces which can cause eddies. We replace this with our carbon tube which is smooth and also has a larger internal volume. Unlike most aftermarket intakes we maximised the size of our intake tube, the OEM inlet tube has an internal diameter of 80.8mm or 3.2” at the filter end. Our tube for cars built after November 2018 has an internal diameter of 109mm or 4.3”. This equates to a massive 82% increase in cross sectional area over stock. The tube smoothly tapers down to the stock turbo inlet to ensure airflow remains as laminar as possible. The tube also has CNC machined fitting for the temperature sensor and the breather adapter.

Bespoke Cone Filter

Our cone filter is made from a non-woven mesh material which is double layered and is ISO tested to ensure that filtration is in line with OEM standards. The filter is cleanable and very stable at high temperatures with the base material being Urethane. The filter incorporates and internal flow guiding cone to help aid the airflow to converge while reducing the possibility of a stagnation point in the middle of the filter space. The filter medium has a significantly larger surface volume than the stock panel filter.
