Performance Gain: 18-25hp, 15-18ft-lb with up to 30hp peak gain
Max Flow Rates: Stock 774 CFM, Eventuri 900 CFM
Introducing our F9X X5M, G09 XM intake. This intake is the result of extensive R&D and testing to improve on the flow path of the stock system. Our system is a complete redesign of the stock airboxes with the aim of reducing pressure loss while increasing the flow rate and keeping inlet temperatures low. With the stock cold air feeds at the front of the car and the turbo inlets facing the rear of the car, the airflow has to negotiate a 180 degrees turn through each airbox resulting in a flow restriction. To overcome this we have introduced an additional cold air feed from the scuttle panel, which results in a more direct flow path to the turbo inlets. The additional feeds allow the intake to have a higher flow rate whilst keeping IATs low and have an additional benefit of de-restricting the sound of the turbos. With the intake openings now facing the cabin, the turbo flutter and pressure release sounds are clearly audible, elevating the driving experience to another level.
NOTE: BMW M Power Decal optional; original M Logo must be transferred from OE engine cover.
This intake has been independently dyno tested by MSL Performance in the UK. Tests were done back to back against the stock airbox and several runs were taken with each configuration. The car tested was without charcoal filters in the stock airboxes. The dyno results show a consistent gain throughout a large part of the RPM range which can be attributed to the turbos reaching peak boost earlier and with a lower wastegate duty cycle due to the higher efficiency of the intake system. The performance gain translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline.
The Eventuri X5M intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow.
Each intake system consists of:
- 2 x Carbon Fiber Patented Venturi Filter Housings
- 2 x Bespoke High Flow Dry Cone Filters
- 2 x Carbon Fiber Twin Air Ducts
- Carbon Fiber Engine Cover
- 2 x EPDM Rear Air Feeds
- Silicon Couplers
- CNC Machined Bracket Mounts
