• Durable Construction: Crafted with high-quality materials for long-lasting performance and reliability.
• Easy Maintenance: Designed for straightforward replacement, maintaining the efficiency of your high-flow intake system.
• Perfect Fit: Specifically engineered for the BMW B58 engine, ensuring compatibility and performance.

This replacement filter is a vital component for BMW enthusiasts looking to maximize the efficiency and effectiveness of their high-flow carbon fiber intake systems.

Following in the footsteps of the immensely popular and heralded intake for the BMW N55 engine, the next generation of 6 cylinder intake takes the same path to success. Improve upon the factory design by increasing flow via a larger air box and filter element thereby improving throttle response and lessening the strain on the turbocharger for maximum efficiency. While box and filter enlargement and redesign is a major factor in ultimately producing a more  potent intake they are not the only variables in creating a more efficient design either. The devil is in the details which is where Dinan thrives. Coupled with maintaining Dinan's standard practice of utilizing a sealed system to ensure as much cold, outside air as possible is employed Dinan engineers focused their attention on the intake pipe itself where numerous improvements could be made. In factory configuration the intake tube comes complete with baffling and a small helmholtz chamber to reduce unwanted sound. As a byproduct these features also cause a more turbulent air flow path which robs the factory system of potential power. These 2 specific details are diametrically opposed to our intended markets desires so the removal of these features was paramount. Through numerous iterations a carbon fiber intake tube was developed that eliminated flow disruptions and allowed the natural sound of an unimpeded intake tract to sing. All told this thorough methodology of design allows the Dinan carbon fiber cold air intake for the B58 engine to elicit gains of 15 HP and 13 TRQ @ 6000 RPM on a completely stock vehicle. An impressive feat on today's turbocharged engines.   

Not to be outdone by the performance side of the equation the B58 intake also is completely made up of carbon fiber unlike 6 cylinder intakes of the past where a mix of materials was used. Not only is the intake completely carbon construction but the quality of the material has been improved over previous generations as well. While looks are surely important, and this piece has that department covered in spades, the improved construction and coating also guarantees that the appearance of the engine bay with the Dinan intake will not be marred over time. Built to present well, perform well, and last the duration, the Dinan B58 carbon fiber cold air intake is a modification that is a must for any high high performance build.

The B58 Eventuri intake system is another example of a “Complete System” principal. It demonstrates the perfect balance between allowing for unrestricted airflow with our open filter housing whilst maintaining low IAT by cold air saturation with our scoop and shield combination. Every detail has been meticulously developed from the prepreg carbon pieces to the double layer heat shields. This intake sets a new benchmark in design and craftsmanship for the B58 platform.

The B58 Eventuri system uses a Patent Pending Carbon fiber Housing which provides an aerodynamically efficient airflow path from the filter to the turbo. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the turbo.

The filter housing comprises of a high flow filter, aluminium cowl, laser cut bracket, carbon heat shroud and the carbon pod itself, which extends to incorporate the MAF sensor and turbo tube. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the integrated MAF intake tube. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack. The carbon filter housing and the inlet tube have been integrated to be one continuous piece. This reduces the number of internal interfaces and allows for smoother airflow to the turbo. The diameter of the tube smoothly transitions from the required diameter at the MAF sensor end to the larger diameter of the turbo inlet.

A lot of attention was placed on the heat shielding since the intake is located next to the exhaust manifold. For this Eventuri used a double layer main shield with a silver finish on the exhaust side and black on the intake side. The silver layer reflects radiant heat from the exhaust and the black layer absorbs and radiant heat on the inlet side. The air gap between the two layers acts as an insulator to stop the conductive heat spreading to the inner layer. 

Each intake system includes:

• Prepreg Carbon Filter Housing and integrated MAF tube
• High Flow Double Cone Air Filter
• Aluminium Cowl for smooth airflow entry
• Prepreg Carbon Scoop
• Prepreg Carbon filter shroud
• CNC Machined MAF Boss
• Double layer main heat shield
• Double layer secondary shield
• Laser Cut Mounting Brackets

Eventuri was founded by true enthusiasts who had a shared passion for cars and performance, engineers that had a background in Aeronautics as well as automotive tuning. After experiencing disappointment time and time again from the claims set forth by the automotive aftermarket, they set out to raise the bar. Their goal? Set a new benchmark for intake design providing true gains, not just "claims."

Designed to use the "venturi effect," Eventuri has created a unique intake system that out-performs the competition. The Venturi effect is when the smooth reduction in cross-sectional area along the length of the housing causes the airflow to increase in velocity. This means more air-flow and smoother delivery, resulting in more power. But that isn't all that sets their design apart. They also use an inverted cone filter that is decoupled from the MAF. This is done because it means the filter no longer dictates the shape of air-flow, thus creating the venturi effect. 

Their systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dyno testing. They strive to publish all the development information to illustrate the depths they go in bringing an intake from concept to reality. Also assuring to only use the highest quality components for style and durability
