The intake boot is a regular issue especially for BMW's, nearly all vehicles have a boot manufactured from rubber with an accordion section in the design for flexibility. This flexible section is typically where the failure comes from, leading to vacuum leak engine codes, rough idle, and increase fuel consumption.
When you upgrade to a Turner silicone intake boot you get a perfect fit that will not only outlast the OE design (meaning any vacuum leaks and rough idle), while also smoothing out airflow within the intake tract. This boot also eliminates the factory intake resonator giving your engine a much more aggressive sound under the hood especially at higher rpm. Available in black or Turner blue color, our intake boot offers either a pop of color or a cohesive, complementary look in your engine bay.
The Turner Motorsport silicone intake boot is manufactured with 5 layers of wire reinforced silicone to prevent collapse under load. Engineered in-house utilizing 3D scanning technology, this boot offers perfect fitment with the factory air box and either single stage or three stage (high output N52) intake manifolds.
Install as a standalone reliability improvement or in addition to our three stage intake manifold and Turner performance tune (available here).
Replaces OE intake boot 13717536004.

At Turner, all our Carbon Fiber Intake Systems are top-of-the-line custom-engineered products that we develop in house. Our S65 Intake is no exception. Turner Carbon Fiber Intakes start with a 3D scan of the factory intake and engine bay. Our engineers use these 3D images of the chassis to design the intake in SolidWorks modeling software. Using a Flow Bench, our Intake is then airflow tested against the factory intake, to ensure optimal airflow improvement against stock. The final product is a beautiful and functional Carbon Fiber Intake, CAD designed for perfect integration with the OEM inlet ducting and stock mounting locations and proven to flow better than factory.
Our Turner S65 Carbon Intake is a monster that perfectly compliments the high revving 4.0l V8 engine. The intake benefits start right at the motor; directly connected to the plenum is a full carbon intake tube with a substantially larger cross sectional area with smooth transitions which results in more airflow available to the engine in high demand scenarios. The inlet tube mounts securely to the full carbon heat shield and is mounted in factory airbox locations while retaining the factory cold air induction tract from the hood. Housed inside the heat shield is a behemoth cone filter to ensure proper filtration and maximize airflow. Turner's S65 intake is designed with air flow in mind and features a roaring induction sound. This intake flows like no other, during testing our intake outperformed the flowbench at over 750CFM, a massive improvement over the factory intake.
Benefits:
There is no other intake on the market like our S65 intake which will make your car unique and stand out from the rest of the E9x M3's.
You get a beautiful carbon design with one of the only full carbon fiber heatshields available.
All the flow - the air on demand will make sure your engine always has room to breathe.
Increased throttle response.
Added induction noise for an intoxicating driving experience.
PART DESIGN:
Designed and engineered in-house using state of the art 3D laser scanning and CAD technology for precision fitment
Hood Inlet Scoop - Directs the flow of cool, ambient air to the heat shield, and directly into the air filter. Seals off with the factory rubber gasket on the lower side of the hood inlet.
Full Carbon Fiber Heat Shield Assembly that utilizes OEM air box mounts and integrates with the factory air intake tract from the hood.
Monstrous 9" cone air filter to maximizes filtration that is able to be serviced/cleaned.
7"x5" Carbon Fiber Inlet Tube providing smooth, direct airflow from the behemoth air filter directly into the plenum.
Fully compatible with the OEM Secondary Air Injection emissions system. Factory hose lock and location.

Introducing the do88 Intake System for BMW 320i and 330i G20 – Engineered for Maximum Performance!
At do88, we understand that filtration, airflow, and heat management are crucial when designing an intake system for turbocharged engines.
Our intake system is designed to provide the turbo with excellent filtration, an optimized airflow path, and consistently low inlet temperatures. One of the key challenges with the B48/B46 engine is the intake system’s location near the exhaust manifold, which generates intense heat and causes rapid heat soak.
High intake air temperatures (IATs) can significantly reduce engine performance, as hot, less dense air makes it harder for the turbo to build boost efficiently. To address this, our fully sealed intake system minimizes heat exposure and maintains low IATs. However, fully sealed systems can face airflow restrictions due to the factory airbox’s single air feed. We resolved this by adding a secondary air feed and incorporating a heat shield into the airbox design to block heat from the exhaust manifold. The large 7” airbox ensures ample airflow around the filter and accommodates strut braces.
We replaced the stock intake hose with a high-flow 102mm (4”) mandrel-bent aluminum pipe paired with a custom silicone hose. The system also features a custom-designed air filter with tightly woven cotton gauze for exceptional filtration. The filter is washable, reusable, and built for long-lasting performance.
Unlike the stock air filter box and intake hose, which are designed with silencers to reduce turbo and induction noise, the do88 system eliminates these elements. This allows for a more pronounced and engaging turbo spool and induction sound, giving you a truly dynamic driving experience.
