BMW Intake Parts

Our Performance CSL Air Filters start with a multi-layer oiled cotton construction that contains millions of smaller fibers to provide superior filtration and performance over the OEM filter. Precisely manufactured for a secure fitment to ensure all the air entering your motor is properly filtered. With the CSL E46 only being offered in Europe, the OEM air filters are produced in much lower quantities making them harder to obtain and drive up the price. Turners solution is a price effective solution that offers premium filtration with increased flow, extended service interval and lifespan.

Having a clean air filter ensures your engine is running at its best efficiency! Proper air flow will help your engine breathe, get the best fuel economy and allow full power throughout the power band. Get the most out of your CSL intake with a new Oiled High Flow Air Filter. These filters can be cleaned, oiled and reused for an extended service life.

Oiled versus Dry Filters:

Although both options will keep the air to your engine clean and improve airflow, there are a few differences to consider when choosing the best filter for you. Oiled filters allow better airflow than dry filters, however they require more maintenance. Oiled filters will likely get dirty faster, needing to be cleaned more regularly. When cleaning an oiled filter, it is necessary to oil them with filter oil afterwards.
Dry filters offer slightly lower airflow but are easier to maintain while still out performing the OE paper filter. Dry filters can be washed with warm soapy water. There is no oiling necessary afterwards.
Both dry and oiled filters flow better than stock and can be reused.

No more slow starts! Does your car feel old? Age may not be the issue at all, your throttle cable bushings are mostly likely worn out and your car has lost its pep!

Your throttle cable is the main connection you have from the gas pedal to the throttle body. Do you have hesitation or delayed pedal response? Think of when you are sitting at a stop light or making a turn into a flow of traffic, you may not realize it but if you haven't replaced your throttle cable and bushings this will require you to apply pressure to the gas pedal before getting feedback which can cause slow starts at stop lights and put you in danger when merging in traffic. These are not issues with old cars, they are issues related to your throttle response!

Symptoms to look for: lackluster/sloppy throttle actuation, deformed throttle cable appearance, and bushing condition. Your throttle cable bushings can be soft, cracked or even disintegrated by now.

Upgrade from failed rubber to new billet aluminum bushings for quick gas pedal response and a better engagement with your car.

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).

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking. 

Maximize performance and reduce intake air temperatures on your E90 335d with the Turner Motorsport Stepped Intercooler. Designed as a direct-fit upgrade for the factory intercooler, this high-efficiency unit increases charge air volume and airflow, helping your diesel-powered BMW run cooler, stronger, and more efficiently.

Cooler air is denser air, and denser air means more power. By reducing intake air temperatures (IATs), this upgraded intercooler allows your M57 engine to pack in more air and fuel per cycle, translating to improved performance across the RPM range.

Engineered for performance and durability, the Turner stepped intercooler features cast aluminum end tanks and a bar-and-plate core design, offering superior thermal efficiency and structural strength. Compared to the stock unit, it delivers a 65% increase in both frontal surface area and internal cross-sectional flow, ensuring better heat dissipation and reduced pressure drop. All of this performance comes in a lightweight package under 20 lbs.

Finished in a stealthy black coating with laser-etched Turner logos, this intercooler not only performs but looks good doing it.

Complete your 24V swap with an intake designed specifically for the job. The Turner 24V Swap Heat-Shield Intake is engineered for E30 engine conversions, delivering cold, dense airflow in tight engine bays while retaining use of the factory air duct.

Most swaps leave you with two less-than-ideal choices: bolt a filter directly to the MAF and suck in hot under-hood air, or cobble together a universal intake that still lacks proper heat shielding. Our swap intake eliminates those compromises.

Our low-profile, heat-shielded design isolates the filter from radiant engine heat, works seamlessly with the stock 3.0" MAF, and supports factory CCV/ICV routing. The result is OEM-like fitment with modern airflow efficiency, no wiring hacks, no vacuum headaches, just a clean, reliable intake solution built for your swap.

Key features:

Heat shield designed to fit M20 and M5X swapped cars — mounts to the frame rail and ties into the ABS mount for rock-solid positioning. Creates a colder air pocket where the factory inlet duct is.
5052 powder-coated aluminum heatshield, stiff, corrosion-resistant, and finished for a long life in the swap environment.
The black silicone intake elbow and coupler is a compliant, high-temperature silicone that grips clamps and resists blow-off during repeated fitment and heat cycles.
Retains stock 3.0" MAF, no adapters needed to run the factory OBD1/OBD2 MAF in a factory-like location.
Designed to preserve stock CCV and ICV hoses for M50/M52 setups, this keeps the typical manifold and crank-vents intact, thereby avoiding vacuum and idle headaches common in swaps.
Stainless-steel hardware for longevity and corrosion resistance.
Fitment & compatibility:

Specifically engineered to work with common 24V conversions where space is tight and retaining OEM-style plumbing is desired. Mounts to factory frame rail/ABS brackets, minimal modification required.

M50/M52 engines are among the most popular 24V choices thanks to robust iron blocks, widespread availability, and strong aftermarket support, making them an excellent pairing for turbo or naturally aspirated builds. Keeping the stock MAF and CCV/ICV routing reduces the troubleshooting surface during install and helps complete your swap faster.
