The AMG GTR Eventuri intake is a fully sealed system which was developed through extensive real world testing and airflow simulation analysis. It features our patented Venturi housings which allow for the smoothest possible airflow to the turbo inlets. The housings encase our bespoke filters which help to shape the airflow and maintain laminar conditions. They have also been maximised in internal volume to reduce restrictions and in doing so we have also redesigned the OEM central cover as it fouls on the significantly larger system. Finally, intake air temperatures are kept steady with the ducts which seal to the filter housings. The AMG GTR intake system has been independently tested by World leading Mercedes tuning company – RENNtech and has been proven to give improved performance in both stock and tuned engines. Each system comes complete with the carbon central cover.

Dyno Testing

Dyno testing was carried out by MSL Performance who are a Mercedes specialist based in the UK. A fully standard A35 AMG was tested with the stock airbox and then with the Eventuri intake back to back whilst ensuring external conditions were the same. As can be seen below the intake provides a gain in performance throughout the RPM range. The highlighted point shows a significant gain of power where the intake allows a higher flow rate to be maintained in the higher RPM range where the stock airbox starts to become a restriction. The resulting gains are noticeable on the road with better throttle response and improved acceleration times. With a tuned A35 we would expect even better gains as the demand from the turbo increases.

Features

The Eventuri A35 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 fiberglass 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:

• Carbon Fiber Airbox
• Bespoke High Flow Dry Cone Filter
• Carbon Fiber Inlet Tube
• CNC Machined Inlet Flange
• Laser Cut Stainless Steel Brackets and ECU Cover
• Silicon Coupler with OEM Specification Clamps

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 sealed so we designed the airbox to encapsulate the filter and at the same time provide a large internal volume. The intake tube passes through a rubber seal in the airbox which ensures heated air does not enter. By relocating the ECU, we have been able to increase the height of the airbox to maximise volume and therefore allows us to use a larger filter.

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 through a rubber section which also has multiple ridges. Our design eliminates this rubber section and therefore provides a smoother cold air entry path. Furthermore to derestrict the intake, we have added a cutout on the cold side of the airbox near the bonnet shut which allows the filter to draw additional air.

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 an 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.
