JCW GP3 performance increase: 15-18 hp, 17-20 ft. per pound
Compatibility: 306hp F56 JCW GP3 and 306hp F54 JCW Clubman
The F5X JCW Eventuri system uses our patented carbon fiber housing that provides an aerodynamically efficient airflow path from the filter to the turbo. Not just another conical filter with a heat shield, but a unique design that harks back to the Venturi effect and maintains laminar flow conditions to reduce drag on the turbo.

The F5X JCW Eventuri system uses our patented carbon fiber housing that provides an aerodynamically efficient airflow path from the filter to the turbo. Not just another conical filter with a heat shield, but a unique design that harks back to the Venturi effect and maintains laminar flow conditions to reduce drag on the turbo.
The F5X JCW Eventuri intake system is a perfect example of our ‘complete system’ principle. It is a sealed system that ensures the turbo does not draw hot air from the engine bay, but is enhanced with a functional bonnet scoop that forces ambient air into the intake duct. This duct has a larger internal volume than the standard version and also draws air from the standard position above the radiator. The combination of a sealed system with an air scoop results in lower intake temperatures than the standard airbox and avoids heat absorption, a common problem especially on the more powerful MINIs. To ensure the smoothest possible flow we use our patented Venturi filter housing which has an integrated MAF section for a seamless flow path to the turbo.
The Eventuri F5X JCW intake system is made up of a number of components designed to perform a specific purpose and manufactured to the highest standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
FILTER HOUSING ASSEMBLY
The filter housing consists of our custom made 2nd generation filter, aluminum inlet bonnet, stainless steel bracket and integrated MAF section. The carbon pod wraps around the reverse mounted filter and gently shapes the airflow to the MAF section which then connects to the stock inlet pipe. This changes the flow path from the OEM airbox where the airflow enters the front of the airbox, changes direction 90 degrees to pass through the panel filter and then changes direction 90 degrees again to pass through the MAF section. Our system is much more direct with the airflow entering the front of the filter housing and moving into the MAF section without abrupt changes in direction. The result is a smoother path from the filter to the turbo inlet pipe and therefore the turbo is able to operate with less resistance.
PATENTED TECHNOLOGY
Our patented filter housing has a smooth reduction in cross-sectional area as it wraps around the filter and tapers towards the tube. This geometry is reminiscent of the Venturi effect, where the airflow accelerates while maintaining laminated conditions. It can be thought of as a large velocity stack - below is a diagram showing how our patented design compares to a typical intake system. Our custom-made filters help the airflow move through the housings and allow for a smooth velocity profile as the airflow exits the housings. Further details can be read on the Technology and Filters pages.
CARBON INTAKE SCOOP
The OEM intake system draws air from behind the front grille, above the radiator. The ambient air intake openings are relatively small and therefore can cause heat to be drawn from the intake, especially on a tuned Mini. The OEM bonnet scoop does not supply air directly to the intake and as the bonnet already has 2 cutouts under the scoop, we decided to utilise this feature and redesign the scoop. Our scoop is a direct replacement for the OEM part and clips into place using the same fixing method. It features 2 intake ramps that guide outside air through existing hood cutouts and into the intake duct (see below). As the car accelerates, more air is forced into the duct keeping intake temperatures to a minimum and avoiding the issue of heat absorption. The scoop has a redesigned profile with a longer top surface to cover the openings which also provides a more aggressive look. Made from 100% pre-preg carbon fiber, the scoop provides an incredible aesthetic to the vehicle. To further enhance the visual feature, we've used a split V-weave with the carbon to give a symmetrical profile that works well as the scoop sits in the centre of the bonnet.
Using existing openings in the bonnet, the ramps on the carbon scoop sit they extend and guide the airflow into the duct. Here is the underside of the hood with the scoop installed.
ENTRY DUCT
The OEM duct draws air only from behind the front grille and is very shallow above the blanking panel. We redesigned the duct to allow air to enter through the grille as well as the scoop. Additionally, our duct has a much larger internal volume that allows the intake system to breathe with less restriction. To protect against engine bay heat, the duct has a flexible rubber lip around the vents at the bottom of the hood that seals the hood when closed. It also has an expandable rubber lip around the filter housing opening which ensures a good seal to the filter and allows movement with the motor.
WATER DRAINAGE
Since we have a direct airflow path to the filter, it is important that we also allow water to drain before reaching the filter. To protect against excessive water ingress, we have designed several features into the intake components as follows.
