Emissions System

VTT is proud to announce a ground-up system designed to give the end-user complete control over their valve cover/ PCV set up. Tired of being told you will run two -10 lines from your VC to your Catch Can? So were we. Now you can run them any way you want, including complete VTA, oil cap one-way breather, etc.

Nothing on the market comes close to the versatility of this setup, and it truly is the ULTIMATE Valve cover and PCV combo.

This option allows you to purchase a ready-to-install kit with all fittings, hoses, check valve, etc for you to bolt on, and go.

Kit Break down is as follows:

Two Catch Cans

One N54 dual can bracket

Banjo Fittings

Vacuum Adapter fitting for Throttle body

Two Hoses from Valve Cover to Cans

Hose from Low side can to Vaccum Adapter fitting

VTA (Vent to Atmosphere) Breather

Inline Check Valve

NOTE This catch can kit is designed to work with the Vargas Modular Valve Cover only and is not compatible with a stock valve cover.

Restore the performance of your BMW M57 3.0L & N57 3.0L Engines with Turner Motorsport's Bosch Oxygen Sensor. If your engine is displaying an oxygen sensor check engine light, it's time to replace it with this high-quality unit. The oxygen sensor plays a crucial role in adjusting fuel mapping for reduced emissions and improved fuel economy by measuring the amount of unburned fuel in the exhaust pipe.

• Ensures proper fuel mapping for reduced emissions
• Improves fuel economy for better mileage
• Restores engine performance and efficiency
• Easy replacement process for quick restoration
• Application of anti-seize prevents thread seizing

Ensure your BMW's engine operates at its best with regular maintenance, as oxygen sensors tend to fail slowly over time.

A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the OEM Bosch oxygen sensor for E30 BMW's with the S14 engine. This sensor is mounted in the manifold before the catalytic converter. OEM replacement for BMW # 11781310838.

Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.  All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.
