BMW Intake Parts

Intake

One thing drivers and cars have in common is the need for air. Induction systems provide a third of the critical necessities for engines to run, so giving your BMW the best way to breathe is paramount in engine performance. If you need to replace your filter, recharge your reusable pod filter, or upgrade your intake, turbos, or intercooler parts, everything can be found below. We have OEM replacements as well as aftermarket performance upgrades to keep your BMW pristine, powerful, and functioning at peak efficiency.

Air Intake Filters

We stock several replacement and performance drop-in air filters for your BMW. Replacing your intake filter (or filters, depending on vehicle) can improve your BMW's performance immediately.

Blow Off Valves & Diverter Valves

Adding a blow off valve or upgrading your diverter valves can change the sound of your vehicle and be an asset in big power setups.

Charge Pipes & Turbo Inlets

The factory BMW charge pipes are prone to cracking, as they are made from brittle plastic. Here at Turner, we sell several brands of replacement charge pipes that are typically made from cast aluminum. We recommend upgrading to hard charge pipes even on stock forced induction vehicles to avoid cracking - we've seen cracking occur on high mileage cars running stock power just as frequently as we do with high horsepower builds.

Intake Boots & Hoses

The intake boot provides a pathway for air from the air flow sensor to the intake manifold. On most BMWs the boot is made of rubber with an accordian shape that allows the engine to shift and vibrate. As with any rubber component the rubber can dry out and crack and that can lead to serious running and drivability issues. A crack in the boot means that air is entering the engine that is not being monitored by the airflow sensor. The engine computer relies on data from the airflow sensor to set the fuel mixture in the engine. Excess unmetered air can result in lean condition faults, rough running, misfires, and other performance issues. For misfire and lean condition faults, check your intake boots first.

As an alternative to the original rubber, we also offer silicone boots that are both stronger and last longer with a 4-layer silicone design. Samco silicone boots can also decrease your BMW's intake turbulence and restriction by replacing the accordian design with a smoothed internal surface. Samco boots are also perfect as part of a kit to eliminate the factory traction control system (sometimes called an ASC delete boot).

Intake Cleaning & Recharging Kits

Cone filter and cold-air intake kits flow great amounts of air through their cotton or foam filters. But to keep contaminants, dirt, debris, and dust out of the engine the filter must be oiled. The oil helps grab the finer particles and prevents them from entering the engine. The oil also works to keep the filter material pliable because a dry filter will eventually crack and break apart. Cone filters must also be cleaned at least once a year. If it's full of debris or an oily sludge it will not flow nearly as much air and any power gains you had will be significantly reduced.
Air filters must be cleaned with their own proprietary brands of cleaner. Mixing cleaning and re-oiling agents is not recommended by each filter manufacturer.

Any time you take the filter out for cleaning you should also clean the film in your HFM / mass air sensor (if equipped).

Intake Manifold Upgrades & Components (DISA, Vacuum, CCV, Et

The intake manifold takes incoming air from the intake and distributes it to each cylinder. Over the years the manifolds have gotten more sophisticated and complex. Most of the additional work that it does is emissions-related - recirculating vapors back into the engine to be re-used. But there are also performance innovations such as BMW's DISA variable intake runners. All of the modern innovations have a part behind it and here you will find replacement components.

In some BMW models there are performance improvements with intake manifolds. These intake manifold upgrades use mostly BMW parts and are a direct replacement for your stock manifold. We offer manifolds and kits to make the conversion work easier.

Intercooler

Installing a larger intercooler in your BMW can lower the temperatures of your charged air, giving you the opportunity to make more power. As forced induction BMWs become more popular, intercoolers will be a staple in terms of modifications.

Mass Air Sensor & Air Flow Meters

We sell OEM air mass sensors, air flow meters, and HFMs (Hot Film Meter) for many BMWs. When the mass air sensor is bad you will notice your engine running out of tune. Your fuel mileage will suffer, throttle response will be poor, and you will notice a lack of power.

There should be a Check Engine Light to alert you that the air sensor is having problems. However, there may not be a fault code for the air meter itself. Often times the code comes up as fuel trim or lean condition. In these cases the air sensor could be just one of a number of potential problems.

We only sell air sensors from Original Equipment Manufacturers like, Bosch, VDO, and Siemens. Please note that HFMs are an electrical part and cannot be returned for refund.

Performance Air Intake Kits

Turner Motorsport offers a variety of Performance Intake options for your BMW, including Genuine BMW, aFe Eventuri, Dinan, Gruppe M, Agency Power, and ECS Tuning.

Throttle Body

We carry a variety of parts related to BMW throttle bodies and throttle body upgrades. Modern BMWs have electronic throttles that need replacement rather than repair. A malfunctioning unit can disable the car so it's important to pay attention to any fault codes related to the 'EML' system. Older mechanical throttles are much more reliable and less prone to any issues. Replacement of any throttle housing is easy and straightforward.

Larger throttle bodies have been advertised for years as a performance upgrade. On their own they will not make any power difference. But combined with other upgrades, such as larger mass air sensors and intakes, they can contribute to power gains. However, we do not currently sell larger throttle bodies. We do offer adapter plates to mount different throttle housings onto your intake manifold. This is most commonly done along with a stand-alone engine management system with or without drive-by-wire control.

Water/Methanol and Nitrous Oxide

Water meth is a great way to get maximum performance out of your forced induction BMW. With all of the new turbo BMWs on the road, water meth injects a mixture of the two into your vehicle's intake to increase octane and reduce detonation. If you're looking to get the most out of your turbo BMW, check out the water meth kits we offer at Turner Motorsport.
