Upgrade your turbo or supercharged setup with TiAL's Q Series Blow-Off Valve, offering an impressive 60% increase in airflow compared to its predecessor. Engineered for both durability and enhanced performance, this valve easily bolts onto any standard TiAL flange without welding.
Constructed from CNC-machined 6061 aluminum alloy, this blow-off valve features a large 1.98'' (50.5mm) valve for optimal airflow. The V-Band design aluminum mounting clamp ensures a clean appearance and utilizes stainless steel hardware for long-lasting corrosion resistance.
This meticulously designed Q Series BOV from TiAL stands as the market's highest flowing blow-off valve. Supporting up to 1,800hp, a single Q BOV demonstrates exceptional high-performance capabilities. Each TiAL Q Series Blow-Off Valve includes the Q Series BOV Assembly, TiAL V-band Clamp, V-band Weld Flange, TiAL Air Fitting, and High-Pressure O-ring.
Optimize your BMW's performance by adjusting your diverter or blow-off valve using this kit containing four springs with varying strengths. When noticing excessive pressure release or a drop in boost pressure, it's an indicator that a stronger spring might be necessary.

This Blow Off, or Dump valve, is for the BMW N20 2.0 Turbo engines that have the electronically controlled bypass valve. It is recommended for any vehicle where the boost pressure has been increased by an ECU software upgrade and for unmodified vehicles operating in warmer climates, as a solution to the many failures that have occurred, where the original rubber diaphragm splits, which causes a loss of boost pressure. Unfortunately the failure doesn’t always result in a check engine light as the valve can still be blown open by the boost pressure, so you may not be aware that you are losing power due to this.
Our alternative is a fully engineered solution offering significantly improved reliability. Our valve is piston based with no diaphragm to fail, and of all aluminium construction. It replaces the original unit with a pressure/vacuum operated piston valve that still also retains the desirable OEM ECU control over valve actuation.

N54 Chargepipe and BOV Kit:
All of the tuning in the world is only as good as the weakest link. More boost in your 135/335 is great! But you will soon learn that some of the factory hardware is not up to the task of handling that extra pressure. One of the first things to fail and cause a boost leak are the factory boost diverter valves. This allows boost to "leak" out of the intake stream and a loss of power from the engine. This ECS Tuning chargepipe upgrade includes a blow-off valve in place of the factory diverter valves. The BOV is higher quality than the diverter valves and will exit intake air to the outside instead of putting it back through the turbo system (which will reduce strain on the turbos). This aluminum chargepipe is also much more robust than the stock plastic factory pipe and the connection to the throttle body is stronger, eliminating another failure point of the stock pipe.
Built-in 1/8" NPT ports allow you to run an additional methanol injection kit (bungs included if you don't want use the ports).
This is a complete kit that includes everything you need to replace the factory chargepipe and diverter valves -
powedercoat chargepipe
ECS Tuning blow-off valve
multiple BOV springs to suit your vacuum/boost needs
vacuum plugs for the stock diverter valve hoses
silicone hose connection to intercooler piping
all hardware and hose clamps with instructions
