Flexible silicone smooths the intake tract while allowing for a range of performance intakes fitments. The ultimate in durability!

In most vehicle applications, the rubber intake elbow found in the intake system is not designed for performance or modification. They were designed to get the job done but when you add a performance filter, intake or tune, the stock elbow will start to show it weakness. The stock rubber elbows disrupt air flow as it passes over the accordion sections causing unwanted turbulence and negating the effects of intake modifications.

With high quality 4 ply construction, the Turner intake boot is strong but flexible, ensuring a secure fit on an OEM or aftermarket intake system. A smooth interior ensures unimpeded airflow, while a smooth, unassuming exterior adds to any engine bay.

Benefits:

Improved throttle response,
Increase induction sound
Increased power output - and power output, Best when paired with an ECS drop-in air filter.(ES4461001 or ES4460965)

Increase the power of your vehicle by utilizing a water/meth injection kit. The purpose of water/meth injection is to reduce combustion temperatures and allow you to run higher boost pressures on pump gas. When using meth injection, pump gas will resist detonation much better because the methanol essentially raises the octane rating of the fuel and will allow you to run much more aggressive street tuning. This AEM kit has more features and components than any other comparably priced injection kits on the market. 1 Gallon tank with built in low level switch Boost referenced progressive controller ?Boost Safe? readiness safety system Check valve integrated into nozzle to prevent unintended fluid flow One injector and two nozzles to cover a wide range of HP levels High Pressure 200psi Recirculation-style pump Progressive Controller: Start Injection Boost 1-11psi.

Get the highly coveted CSL experience with your S54! Roaring induction noise, aesthetics and increased performance are just the tip of the iceberg when installing this legendary intake. Its not fair that Europe always gets the cool cars and widgets (excluding E36 LTW, thank you BMW.) The E46 CSL M3 is world renowned as one of the finest cars BMW produced. Covered with parts exclusive to the CSL model, the intake system is one of the most sought after components for non-CSL owners. The CSL intake plenum is your chance to experience the life altering CSL intake. For starters, after installation you are left with a completely transformed engine bay.

The CSL intake does not feature any sound dampening or silencer and allows your S54 to let out its full roar that can be heard clear through the cabin for an experience that makes you smile ear to ear. Paired with the Active Autowerke Alpha N Tune we have seen gains of up to 43 hp and 26 Ftlbs of torque in a healthy naturally aspirated S54.

Universal High-Flow Air Filter

Give your engine the airflow it deserves with this reusable, high-performance air filter—perfect as a direct replacement for an ECS intake system or as the finishing touch for your custom intake project.
Dimensions: 4.5" Base OD • 6" Filter Height • 3.5" Top OD

Oiled vs. Dry Filters — Which Is Right for You?

Oiled Filters

Offer slightly higher airflow for maximum performance

Require more frequent cleaning

Must be re-oiled after each cleaning

Long-term reusable design saves money over disposable paper filters

Dry Filters

Provide excellent airflow with minimal maintenance

Easily cleaned with warm, soapy water—no oiling required

Still flow significantly better than OE paper filters

Fully reusable and cost-effective

Both versions deliver superior performance over stock filters while offering the long-term benefit of reusability. Choose the option that best fits your maintenance style and performance goals.

K&N's drop-in air intake filter is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance drop-in intake filter. These are very easy to remove and maintain. Turner Motorsport recommends this as one of the first maintenance/modifications you make to your vehicle after you purchase! 

K&N's drop in air filters allow increased airflow - dirt and particles stick to the oil on these filters, making them more effective than traditional paper filters in terms of protection. Additionally, K&N believes their filters are more efficient than paper filers - this means more oxygen getting into the engine, allowing vaporized fuel to burn more efficiently and increasing horsepower and fuel economy. The best of both worlds!

This item fits the following BMWs:
2004-2010 E60 BMW 525i 525xi 528i 528xi 530i 530xi
2006-2008 E85 BMW Z4 M Roadster Z4 M Coupe

The Snow Performance Stage 3 Boost Cooler brings 2D mapped water-methanol injection delivery to your DI (direct fuel injected) and forced induction (turbocharged/supercharged) vehicle. The Stage 3 creates a 2Dinjection map based off boost and fuel pressure sensor input to deliver an extremely accurate amount of water-methanol when the engine needs it most. Bringing fuel pressure into the mix allows the injection curve to be extended past specific boost points for greater range/control. None invasive, the Stage3 Boost Cooler controller is designed to mount on the steering column or the dash so no additional gauge pods need to be purchased and functions as a boost gauge, water-meth controller and fuel system monitor all in one! Proven to reduce the air inlet temperature by up to 100 degrees and increase octane by 25points for maximum HP and cooling . Comes with adjustable Stage 3 water-meth controller, 4AN fittings, and stainless steel braided line to mount pump/tank in engine bay of vehicle.

Maximum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 1.6mm powder-coated steel heat shield that blocks hot air from entering the filter. Each intake kit has a custom application-specific aFe cone filter that replaces the stock panel filter. The larger aFe Pro 5 R oiled filter, combined with the heat shield, improves airflow by 90%! By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horsepower and torque, improving acceleration and throttle response, and producing a more aggressive engine note. Step-by-step instructions for a quick and easy install are included.
aFe reports a gain of 11hp and 10ft/lbs of torque on the Z4 M.

This version uses aFe's highest flowing filter - the Pro 5 R. This filter uses a 5-layer, lightly-oiled cotton gauze material to filter out dirt and particulates, while improving airflow through the intake. For the best flowing filter, with the best performance gain, we always recommend the oiled aFe filter over the dry versions. The Pro 5 R filter is washable and re-oiled using aFe's approved Restore Kit.

This aFe intake kit fits all 2006, 2007, and 2008 MZ4 including:
2006-2008 E85 MZ4 BMW M Roadster
2006-2008 E86 MZ4 BMW M Coupe

Looking to make loads of power on pump gas? Enter: water/methanol injection. Regardless if you're tuned for conventional pump gas, E85, or race fuel, use of a properly configured and integrated water/meth system will reduce temperatures, allowing you to make more power than on just conventional fuel alone. Select your engine-specific nozzles (which are standard 1/8" NPT and install in most aftermarket chargepipes), your tank to mount in the trunk, upgraded steel braided lines if you so choose, and some boost juice and you just need a management solution! Optionally, add a BMS FSB for JB4 integration!
