With so many aftermarket intakes available, the natural question arises:
“So what’s so special about the Eventuri Intakes?”
There are two main elements in explaining the answer to what sets us apart from the rest:
- The unique Eventuri filter housing design
- Our Bespoke Filters
- Our emphasis on creating a “Complete Solution”
The Eventuri Filter Housing
On first glance the Eventuri intake may look similar to the majority of aftermarket intakes out there however, unlike the majority which use the same cone filter/tube/heat shield configuration, the Eventuri design is fundamentally different. To appreciate the difference we will firstly look at the conventional cone filter intake design:
Most aftermarket intakes use a cone filter mated to the engine inlet tube (usually with the Air Mass sensor ie. MAF tube) and have some sort of heat shield surrounding the cone. In this configuration – the airflow has to negotiate a path from the large diameter at the base of the filter through to the smaller diameter of the MAF tube in a relatively short distance. There is usually a velocity stack at the base of the filter to help the transition however, this is also relatively short. The sudden transition in geometry is detrimental for airflow as turbulence and dead spots arise – particularly in the low/mid RPM range as flow starts to develop (transient phase). This results in a loss of low/mid range torque as flow velocity through the “less restrictive” filter is impeded. The seldom gains in power only surface in the last few hundred RPM range and even then do not live up to the claims.
The Eventuri is a new type of intake design which is patent pending and this is why: We use a cone filter – BUT here it is inverted and decoupled from the MAF tube. By removing the direct connection between the filter and the MAF tube, the filter is not now dictating the shape of the airflow. This is now being done by the carbon housing, which also acts as a heat shield. The carbon housing shapes the flow smoothly down to the MAF tube over the entire distance of the housing. This means that we keep laminar conditions throughout the intake into the MAF tube which is a lot more efficient. Furthermore, the funnel-shaped housing invokes the Venturi effect where the smooth reduction in cross-sectional area along the length of the housing causes the airflow to increase in velocity. Essentially the ENTIRE housing acts as a velocity stack. On the road – this translates not only to more power but smoother delivery and a sharper throttle response as the airflow is not inhibited by abrupt geometry changes and so is more likely to remain laminar.
