Eventuri BMW G29 Z4M Carbon Performance Intake

PRODUCT SPECIFICATION 

Heat and Volume are the main considerations when designing an intake for turbocharged engines. In the BMW G29 Z4M, the intake system is located next to the exhaust manifold which rapidly heat soaks the engine bay. High temperatures are detrimental to engine performance as the turbo would have to build boost with heated, less dense air and so the only way to ensure IAT’s are kept to a minimum is for a fully sealed intake. This, however, results in a restriction with only one stock air feed to draw air in from.

During development, Eventuri noticed an additional opening into the wheel arch area and took advantage of this by adding a secondary feed to the airbox. Furthermore, the sealed airbox also has a heat shield with gold reflective to minimise the radiative heat transfer from the exhaust manifold. In order to maximise volume, they made the airbox as large as possible with a recess for potential strut braces. The stock convoluted intake tube is replaced with a smooth carbon tube which is also larger in internal volume with a starting internal diameter of 111mm (4.4″) smoothly tapering down to match the turbo inlet. The tube provides a smooth path from the filter to the turbo inlet. Finally, Eventuri uses a custom-made high-flow dry filter that is ISO-tested for filtration performance and has a larger filtration area than the stock filter.

The Eventuri BMW G29 Z4M 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 fibre with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system consists of:

• Carbon Fiber Airbox with Dual Feeds
• Bespoke High Flow Dry Cone Filter
• Carbon Fiber Inlet Tube with 111mm opening ID
• CNC Machined Temperature Sensor Mount
• CNC Machined Breather adapter
• Heat Shield with Gold Reflective Backing
• Laser Cut Stainless Steel Brackets
• Silicon Coupler with OEM Specification Clamps
