Why is Eventuri different from other performance intake on the market?

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:

  1. The unique Eventuri filter housing design
  2. 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.


The Complete Solution

The second element to our design – which is as important, is our emphasis on creating a complete solution. We dedicate a lot of design effort on ensuring the filter housings are provided with ambient air in the most efficient way possible. Allowing the filters to draw in heated air from the engine bay defeats the objective and in many cases is the cause of an actual loss in power over the stock system once the engine bay is heat soaked. Simply using heat shields is not enough – there must also be a method of channeling cold air into the intake. This is where we have seen some companies use “scoops” but on closer inspection are usually very flat and almost perpendicular to the oncoming air. Not the ideal solution for trying to redirect air at high speeds! Our scoop designs have, where possible a curved face for as much of the exposed area as possible in order to smoothly redirect incoming air to the filters. In doing so we ensure that engine bay heat is displaced and so intake air temperatures are kept as low as possible.


From scoop to duct to housing to inlet tubing – by utilizing organic shapes, we invest a great deal of time and effort in providing a smooth path for the airflow to follow. Hence ensuring maximum efficiency of the system.


On The Road

With a smooth inlet track to the MAF tube and by ensuring we have an effective cold air supply to the filters, the resultant performance increases translate to an enhanced driving experience:

  • Throttle response is sharper as air speeds in the inlet track are maintained by the Venturi effect.
  • Low/mid range torque is increased which improves general driveability. The car feels more aggressive and eager to drive.
  • Top end power is increased as the engine is allowed to draw in cold air with less restriction.

Couple the performance increase with a more audible and sonorous induction sound and the overall driving experience is much more involving and enjoyable.
