N54 (3.0TT) Diverter Valve Charge Pipe

Introducing our new Diverter Valve Charge Pipe for the N54 Engine!  Fits all BMW's utilizing the N54 engine (135i, 335i, 535i, X6 xDrive35i, and Z4 sDrive35i).

• Now available for the 2009+ N54 Engines!
• Increase throttle response and decreases turbo lag.
• Compatible with factory diverter valves or aftermarket factory style diverter valves.
• Lightweight High Grade 6061 Aluminum Piping.
• Throttle body matched 3" piping.
• Retains factory style o-ring throttle body lock flange.  Precision CNC machined throttle body flange ensures leak free connection to throttle body.  Quick and easy connection and disconnection to throttle body.  Ideal connection compared to the silicone hose and hose clamp connection found in all other aftermarket diverter valve upgrade pipes available in the marketplace.
• Precision CNC machined MAP sensor flange ensures leak free connection.
• Diverter Valve Charge Pipe features beaded ends and T-bolt clamps to prevent intercooler piping from coming off from boost.
• Factory diverter valve sound baffle, which causes turbulence in the factory pipe, is removed.
• Optional Type III Hard Black Anodizing (for stealth and OEM look).  Hard anodizing helps improve durability of intercooler piping.  Resists bent or dented piping.
• Includes all hardware needed to install.
• Includes all hardware for complete installation.
• Developed under the harsh conditions of racing on our 135i Race Car.
• Optional TIAL Q Blow Off Valve available in 5 different colors (black, polished silver, red, blue and purple).
• Optional Synapse Synchronic Blow Off Valve now available!!!
• Optional HKS Super Sequential Blow Off Valve now available!!!
• Limited Lifetime Warranty.

Again, another parts development directly from our 135i Time Attack racing program.  The factory diverter valves were causing an issue of not being able to hold up against the rigors of high boost application, therefore they needed to be replaced.  Thus attention was brough to the factory diverter valve pipe and the need to optimize for maximum performance on a race car facilitated the need for a new pipe to be built.  Often ignored, charged intake airflow characteristics greatly affect throttle response, turbo lag and ultimately maximum power potential.  Smooth bends and minimal obstructions are ideal.  This is not the case with the factory diverter valve charge pipe.  On the factory diverter valve chargepipe features a sound baffle for the diverter valves.  This sound baffle is connected on the side of the factory diverter valve  charge pipe which splits airflow.  This causes turbulence inside the pipe which slows the charge intake air velocity (speed of the air traveling inside the pipe).  By removing this turbulence (by eliminating the factory diverter valve sound baffle), increased throttle response, decrease turbo lag and ultimately higher maximum power potential can be realized.  Our Diverter Valve  Charge Pipe eliminates this sound baffle and thus eliminating the unneccesary turbulence in the diverter valve pipe, keeping charge intake air velocity at it's maximum.  3" 6061 Aluminum piping was used to properly match the size of the throttle body as well.

Since one of the reasons for changing out the factory diverter valves was to prevent boost leaks (from prematurely opening on high boost), causing boost leaks while upgrading the diverter valve would be counterproductive.  The connection at the throttle body was looked over very carefully.  The factory diverter valve is connected to the throttle body using an o-ring inside the throttle body flange which is locked in place by a c-clip, which works very well.  It also make removal/installation quick and easy.  The throttle body lip is machined to accept this c-clip.  Iti s not designed for a silicone hose connection which is used by all the other brand diverter valve pipe upgrades in the market.  The throttle body lip is too short and there are no "beads" to prevent the silicone hose from blowing off under boost.  Even though it is the easiest way to  "rig" together, it is not ideal.  The best way to connect the new diverter valve pipe to the throttle body is to replicate the same connection.  Therefore, we CNC machined our own replica throttle body flange that utilizes the same factory o-ring and c-clip for our Diverter Valve Charge Pipe.

The same issue came with the MAP sensor.  The MAP sensor seals to the factory diverter valve pipe via a o-ring on the sensor itself.  Having a hole in a silicone hose will definitely cause a boost leak as it will not properly seal.  Therefore, again we CNC machined our own replica MAP sensor flange that utilizes the same factory o-ring seal.

The Diverter Valve Charge Pipe is available in the same 2 finish options as our intercoolers.  It is available in a mirror polish finish.  It is also available in our Type III Hard Black Anodizing for the guys that want the stealthy, factory look.  An added benefit of the Type III Hard Black Anodizing is that it hardens the aluminum piping and makes it more durable against accidental damage (like dropping the pipe).

We also offer our Diverter Valve Charge Pipe in any anodizing color of the rainbow you want (special order) and is available in only Type II Anodizing (asthetics).  It is available as a special order item and is not stock. 

Brush (or plain) finish is also available.

The standard option for our Diverter Valve Upgrade Pipe is designed for either the factory diverter valves or aftermarket "factory style" diverter valve.  Also available is the TIAL Blow Off Valve option which utilizes the TIAL Q Blow Off Valve (BOV).  The TIAL Q BOV features a large 50mm (2") valve to quickly discharged built up boost pressure.  Since the TIAL Q BOV vents to the atmosphere which causes no restriction to venting boost, it reacts faster than recirculated diverter valves.  The internal valve spring can be changed out to different spring rates which allow adjustability.  This allows versatility as it allows you to increase the spring pressure in the future for when you run higher boost levels.  Therefore, it eliminates the need to purchase another BOV or diverter valve if you increase boost levels.  Essentially, this is the last blow off valve you will ever buy.  The TIAL Q BOV is available in 6 different colors: black, polished silver, red, blue and purple.  The black color option is standard.  If you want any other color, please specify when ordering.
