Turbonetics introduces compressor anti-surge and turbocharger protection for the BMW 335i coupe and sedan. Designed to minimize wear on the internal bearings of the turbochargers and provide increased throttle response, the 335i BOV kit combines increased durability and performance.

BMW owners have always understood the link between form and function. Just like the factories the vehicles come from aftermarket parts need to live up to design and performance. The Turbonetics 335i BOV kit surpasses both standards. As today's cars become more and more finely tuned to wring every last bit of performance and fuel economy, certain parts are called on more than others. The forced induction system on the 335i's N54 engine platform is pushed to greater limits with small twin turbochargers come from the factory running higher than average boost levels. With higher boost comes added stress on the turbochargers rotating components. A well designed and efficient blow-off valve kit helps to alleviate unnecessary wear and strain on the turbochargers internal thrust bearings, turbine wheel shaft, increase lifespan and improve performance.

The compressor blow-off valve is placed after the intercooler and before the throttle body to help eliminate the pressurized air. Vacuum controlled, the BOV receives a signal from inside the intake manifold or just after the throttle body, pulling up on a diaphragm, causing a valve to open inside the unit. The pressurized air that is discharged is then routed back to the inlet of the turbocharger or vented to atmosphere protecting the compressor from surge and assisting in maintaining the speed at which the turbochargers wheels are turning improving throttle response and drivability.
