Bespoke Filter Design
We are proud to announce Eventuri’s bespoke filter cones for 2018. Replace your old filter(s) on your existing Eventuri intake and improve performance at the same time by simply upgrading to the newly designed filter Type 151 and get even more bhp from your intake system!

The Type 151 Replacement Filter is designed to fit the following vehicles:

• Audi B8 RS4/RS5
• BMW F8X M3/M4
• FK2 Civic Type R

This filter is a custom design which was developed to provide optimum airflow through Eventuri’s housings where the filter is reverse mounted. It is a direct replacement for all of Eventuri intakes which use Eventuri carbon housings and will be fitted to all new intakes from February 2018.

Currently on offer for a limited time, so if you already have an Eventuri intake manufactured before February 2018, you can upgrade your original designed filter at a very reasonable price and improve the performance of your Eventuri intake even further!

We have seen the following bhp increase from our dyno testing when replacing the V1 filter with the upgraded V2 filter:

+12bhp on the BMW F80 F82 M3/M4 Intake System (Type 151)

+9.3bhp on the BMW F1X M5/M6 Intake System (Type 661)

+4.3bhp on the Honda Type-R FK2 Intake System (Type 661)

Please scroll down to see the dyno graph for more details.

Filtration and Construction

Unlike many other intake companies who use a generic filter, we have carried out extensive R&D and invested significant funds into our own unique filter design, so that it is optimised in our Patent Pending reverse mounted configuration. The filtration medium is constructed from non-woven mesh and is ISO 5011 tested which conforms to the same filtration standard as OEM filters. The mesh is double layered and is dry which means that it will not damage MAF sensors with oil. Our filters feature 2 flow directing cones which have been carefully modelled to direct airflow as follows:

1. Internal Cone – designed to help direct incoming airflow through the filter and to create an even velocity profile across the length of the filtration material. This cone effectively helps airflow disperse across the filter without turbulence.

2. External Cone – CNC machined, with a very unique profile, which was extensively optimised to help pull the airflow down to the center and transition smoothly into the downstream tubing. This cone creates a controlled region of turbulence around the tip which increases the convergence speed of the air, so that the connecting tubing has a higher velocity profile of airflow leading to the engine.

Airflow

The resulting flow through the filter and also smooth at the exit of the intake, to the connecting tube is smooth with a high velocity profile. In real terms, this means that the engine is able to draw air very efficiently, and the driver will be able to notice a sharper throttle response, as well as the power and torque improvements. Where the engine has a turbo(s) it will be able to achieve peak boost earlier as it will be working with less resistance. Tests have shown that our systems reduce the waste gate duty cycle by a significant percentage over the OEM system.

The following diagrams are CFD simulations showing velocity streamlines through our system – with the new filter and the original filter.

Resulting Improvements

Through Dyno testing the Eventuri intakes back-to-back with the original filters vs the upgraded filters, we have found an additional power and torque gain. This validates our theoretical modelling and proves that the upgraded filters really have a significant impact on the airflow through the intake. The power gains over and above the original filters vary between vehicles, but here are some of the results we have measured so far. Please note – these graphs show the Eventuri intake with original filter vs upgraded filters. Not against the stock airboxes – which will now be an even larger gain!

Aesthetics

Aside from the technical improvements, the upgraded filters resemble the engines of an aircraft – resulting in a dynamic overall aesthetic once installed into the carbon housings. From the reverse – looking into the carbon housing – the laser etched outer cap is clearly visible surrounded by the filter mesh. An awe-inspiring sight.
