Product Overview
Eventuri BMW M5 M8 Turbo Inlets – Carbon Fibre Upgrade
The Eventuri Carbon Fibre Turbo Inlets EVE-F9XM5M8-CHG have been developed to improve the airflow path between the intake system and turbochargers on BMW’s high-performance M5 and M8 models.
The factory BMW turbo inlet pipes reduce in diameter shortly after the connection to the intake system. This narrowing can become an airflow restriction, particularly on vehicles running increased boost or additional engine tuning.
Eventuri redesigned this section using a larger-volume carbon fibre inlet with a smoother internal path leading towards each turbocharger. The result is a less restrictive route for incoming air and an inlet system designed to allow the turbochargers to operate more efficiently.
Larger-Volume Turbo Inlet Design
Rather than simply enlarging the connection point, Eventuri maintains a larger internal section further along the inlet towards the turbocharger.
The smoother curvature helps minimise unnecessary changes in airflow direction while reducing the restriction associated with the original inlet geometry.
This makes the Eventuri BMW M5 M8 turbo inlets particularly suitable for performance-focused vehicles where maintaining efficient airflow becomes increasingly important as boost pressure and engine output rise.
Designed to Complement the Eventuri Intake
These turbo inlets are an ideal addition to the Eventuri BMW M5/M8 intake system, extending the improved airflow path from the air intake all the way towards the turbochargers.
However, an aftermarket Eventuri intake is not required.
The EVE-F9XM5M8-CHG turbo inlets are also designed to work with the original BMW airboxes, making them suitable as either a standalone airflow upgrade or part of a complete Eventuri intake package.
Prepreg Carbon Fibre Construction
Each inlet is manufactured using high-temperature prepreg carbon fibre, providing the combination of strength, heat resistance and premium appearance expected from an Eventuri component.
The carbon inlet pair is combined with precision CNC-machined hardware to provide accurate interfaces with the factory turbocharger and breather system.
The kit includes:
- Prepreg carbon fibre inlet pair
- CNC-machined turbo flanges
- CNC-machined breather valve assembly
Developed Through Real-World Testing
During development, Eventuri evaluated different inlet configurations, including a larger version that would have required an oversized intake connection.
Testing showed that increasing the connection size beyond the final design provided no additional performance advantage.
Eventuri therefore selected the version that delivered the required airflow improvement while remaining compatible with both its existing intake system and the original BMW airboxes.
Eventuri Performance Testing
Eventuri tested the inlet system using GPS-based acceleration measurements under controlled same-day conditions.
With the turbo inlets installed, the manufacturer recorded a 0.12-second reduction in 60–130 mph acceleration time.
Individual results will vary depending on vehicle specification, modifications, software calibration, road conditions, fuel and environmental conditions.
Ideal for Standard and Modified S63 Engines
The Eventuri carbon turbo inlets can be used on standard vehicles but become especially relevant as airflow demand increases.
They are an excellent complementary upgrade for cars fitted with:
- Performance intake systems
- ECU software
- Higher boost calibrations
- Upgraded exhaust systems
- Downpipes
- Hybrid or upgraded turbochargers
- Other supporting S63 engine modifications
By improving one of the restrictive sections immediately before the turbochargers, the inlet system helps create a more efficient overall induction path.
Premium Engine Bay Appearance
In addition to their performance function, the exposed prepreg carbon construction significantly enhances the appearance of the BMW engine bay.
The gloss carbon finish complements Eventuri intake systems particularly well and provides an OEM-quality performance appearance suitable for both road cars and extensively modified BMW M builds.
Why Choose Eventuri EVE-F9XM5M8-CHG?

Frequently Asked Questions
Do Eventuri EVE-F9XM5M8-CHG turbo inlets fit the BMW F90 M5?
Yes. EVE-F9XM5M8-CHG is designed for compatible BMW F90 M5 applications equipped with the S63 twin-turbo V8.
Do these Eventuri turbo inlets fit the BMW M8?
The inlet set is used on compatible F9X-generation BMW M8 applications, including F91, F92 and F93 models. Vehicle specification should still be confirmed before ordering.
Can I use these turbo inlets with the standard BMW airboxes?
Yes. The Eventuri inlet design is compatible with the factory BMW airboxes.
Do I need an Eventuri intake system?
No. The inlets can be used with the factory airboxes, although they are also designed to complement the Eventuri intake system.
What are the Eventuri turbo inlets made from?
The inlet pipes are manufactured from high-temperature prepreg carbon fibre and use CNC-machined components at critical connection points.
What comes in the EVE-F9XM5M8-CHG kit?
The kit includes a pair of prepreg carbon turbo inlets, CNC-machined turbo flanges and a CNC-machined breather valve assembly.
Will these turbo inlets increase power?
Their primary purpose is to reduce airflow restriction immediately before the turbochargers. Actual power improvements depend on the vehicle’s specification, boost level, ECU calibration and supporting modifications.
Are these suitable for tuned BMW M5 and M8 models?
Yes. The reduced inlet restriction makes this type of upgrade particularly relevant on vehicles requiring increased airflow, including higher-boost and modified S63 applications.
What performance difference did Eventuri record?
Eventuri reported a 0.12-second improvement in its 60–130 mph acceleration testing after fitting the inlet system. Results on individual vehicles can vary.
