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.

Features:

• 5 layers of wire reinforced silicone
• Perfect fitment with factory airbox
• Compatible with single stage or three stage manifold

Full carbon fiber intake to increase flow, performance and aesthetics! Dual inlet design for maximized air flow while retaining the OEM+ fitment.

The most common N55 intake utilizes a short plastic tube and oversized cone filter; it is your job to have better taste than the common N55 owner. This carbon intake changes the whole image of the N55 engine while maintaining a flow of cool air and added induction noise. With a dual inlet design the engine bay retains its functionality while adding a second inlet to provide your engine with improved air flow and sound. To ensure the engine gets the coolest air possible the second inlet is located in the "sweet spot" on the cold side of the engine for the lowest intake air temps and most air flow possible. The cone filter features a bellmouth velocity stack filter that creates the satisfying flutter after letting of the throttle.

Our Turner Carbon Fiber Intakes start with a 3D scan of the factory intake and engine bay. Engineers use the 3D imaging of the chassis to design the intake in SolidWorks modeling software. Using a Flow Bench, the 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.

Key Benefits:

Increased flow over the factory intake
Carbon fiber airbox and intake tube with gloss clear coat for UV protection

Carbon fiber airboxes are manufactured using 2X2 twill weave carbon fiber and protected with a gloss finish clear coat for UV resistance to match the intake tube.
Air box mounts in stock location with supplied hardware.
- Air Filter

Conical hi-flow reusable air filter; featuring 8 ply oiled cotton gauze construction to maximize filtration efficiency.
Bellmouth (velocity stack) filter flange inlet to reduce turbulence in order to maximize flow.
Product Development:

Turner N55 Intake System was designed, engineered, tested and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer and rigorous long term product testing. Performance data metrics are collected utilizing Mustang AWD 500 SE in ground dyno and in-house Superflow SF-750 Flowbench.

Over 13 CFM more airflow than factory intake plenum! Beautiful Carbon Fiber construction with a roaring induction sound!

At Turner Motorsport, all our Carbon Fiber Intake Systems are top-of-the-line custom-engineered products that we developed in house. Our engineers took it upon themselves to design a prettier, cost effective Carbon Fiber Intake Plenum for S65 owners to compliment our E9x Carbon Fiber Intake System while retaining OEM features. Our S65 Carbon Intake Plenum is no different. Our 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 plenum in SolidWorks modeling software. Using a Flow Bench, the Intake Plenum 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 Plenum, CAD designed for perfect integration with the OEM inlet ducting and stock mounting locations. Our Carbon fiber Intake trumpets flow an average of 13 CFM over the stock BMW intake.

Our E9X M3 S65 Carbon Fiber Intake Plenum is made from 100% high grade prepreg 2x2 twill weave carbon including the internal trumpets, this plenum replaces the OEM plastic plenum allowing the naturally aspirated BMW V8 engine to generate more inductions sounds taking the driving experience of the M3 to a whole new level. The raw V8 rumble gives the M3 an almost CSL like sound and is truly an intoxicating experience. We went through several iterations using different carbon thicknesses to fine tune the sound and the resulting plenum generates an almost unbelievable induction volume and tone.

Our Carbon Fiber Intake Plenum can be used with the OEM airbox or any aftermarket intake system. Paired with our E9X M3 intake system, you're sure to upgrade the look and sound of your S65 engine.

The diverter valve is responsible for redirecting boost away from the intake when it's not needed. Other cars use a blow-off valve to vent the pressurized air into the atmosphere (the whoosh sound commonly heard on turbo engines) but BMW and other makers use a diverter valve to keep the air circulating through the intake for emissions purposes. A failing diverter valve will lead to a boost leak as turbocharged air leaks past the seals instead of going into the engine when you want it. This is a minor issue on stock engines but a bigger issue on tuned or heavily modded engines (those will use an aluminum diverter valve instead of the stock plastic). The factory diverter valve is plastic which is prone to cracking and electric which will fail without warning. This is a direct replacement diverter valve for cars with the N55 and S63 (X5M/X6M) engines.

N55 takes 1 diverter valve.
S63 takes 2 diverter valves (1 per turbo).

This item fits the following BMW Chassis:
E70 X5M,E71 X6M,E70 X5 X5,E71 X6,E82,E90,E92,E93,F06,F10,F12,F13,F15,F16,F22,F25 X3,F26 X4 X4,F30,F32,F33,F34,F36
S63 engine applies to X5M/X6M only. Fxx M5/M6 uses S63TU engine and does not use a diverter valve at all.
