DO88 intake system for BMW M2 M3 M4 G80 G82 G87 S58 engine

Description

Description
do88 is proud to present the complete carbon fiber intake system for BMW M2 M3 M4 (G80 G82 G87), designed for high power outputs!

When designing a new intake system for a turbocharged engine, three critical factors are vital: filtration, airflow, and thermal management. Our do88 intake system is designed to optimize these elements: air filtration, improved airflow, and maintaining low intake temperatures for turbochargers. The design of the airboxes—including their shape, volume, and the materials used in their construction—is precisely engineered to maximize airflow to the engine, thereby improving performance.

High intake air temperatures negatively impact engine performance because the turbos must generate pressure using hot, less dense air. Therefore, a fully sealed intake system is essential to minimize Intake Air Temperatures (IATs). However, such a system presents a challenge due to its restrictive nature, relying solely on the stock air intakes at the bottom of the air filter boxes for air intake. During development, it became clear that to eliminate this restriction, the system required additional fresh air intakes. To address this, we introduced additional air intake openings behind the headlights on each side. To ensure sufficient air volume around the air filters, we designed large 7,8-inch air boxes, which also provide ample space for the CSL suspension brace.

As a replacement for the stock plastic intake ducts, we designed large, smooth carbon fiber tubes. These start with a 105mm (4,1-inch) diameter at the end of the air filter and taper seamlessly to 3,25 inches, matching our custom turbo inlets. Attached to our carbon tubes is our large, custom-designed air filter. This filter features a densely woven cotton gauze, ensuring clean airflow. Engineered for durability and efficiency, the filter is washable and reusable, promoting optimal performance and a long service life.

Our design sets us apart from most aftermarket intake systems. We've gone the extra mile by developing custom turbo inlets that replace the restrictive OE plastic inlets. Original equipment (OE) inlets have connection sizes of only 61mm and 72mm. In contrast, our custom-cast aluminum turbo inlets have significantly larger 83mm connections. To ensure the versatility and longevity of our system, we've implemented an innovative gasket and adapter sleeve design. Our cast inlets provide a 53,6mm opening to our compressor housing inlet sleeves, exceeding the flow diameter of the OE parts. We seal to the surface of the flat-screw flange, rather than to the side of the tube insertion. This design allows our turbo inlets to fit both OE and hybrid turbos, such as the Pure S58 STG2+ and TTE940, by including various sleeves that align with the inner diameter of the compressor housing and our turbo inlets, ensuring a seamless fit.

Key Features:

Large custom-made, pre-oiled 105mm (4,1″) cotton air filter with densely woven cotton gauze.
A completely closed/sealed design, ensuring that only cold air is supplied to keep IATs low.
Produces an improved induction sound from the turbo and bypass valves, without causing the annoying noise often caused by a fully open air intake.
Precision-engineered, optimized for unrestricted airflow.
Optimized for tuned engines, hybrid turbos and big turbo kits.
Increases airflow by 24%
Reduces pressure drop and stress on factory components compared to OE intake.
Improves throttle and turbo response
Smooth design without sharp bends or restrictions.
Compatible with most future modifications, i.e., turbo upgrades.
Clear varnish resistant to UV and heat for long-lasting protection.
Washable air filter for optimal performance and a long service life. We recommend cleaning the air filter every 20.000 km. Please use a universal cleaning product designed for cotton air filters. For example, you can use BMC cleaning fluid with part number "WADET500".
