Introducing our long anticipated new Cold Side Cast "J" Charge Pipe for the 2015+ BMW M2 Competition, M3 and M4 S55 Twin Turbo Engine!
Turn up the boost with a tune and find your factory "J" charge pipe break apart? The factory charge pipe is made out of plastic and was not designed to handle the higher boost levels. Well, fear not! The solution is here! Replace it with a higher flowing, stronger cast aluminum "J" charge pipe! Made of cast 6061 high grade aluminum, this will never happen again (backed by our Limited Lifetime Warranty)!
Our Cold Side Charge Pipe is casted from 6061 aluminum. Why did we cast this piece instead of mandrel bent tubing? The factory "J" Charge Pipe runs from the air/water intercooler assembly to the throttle body. It takes a very tight "J" turn which cannot be mandrel bent. The only way accomplish this with mandrel bent tubing is to cut the mandrel bends at an off angle and "rig" pieces together. You will see many other brand "J" pipes in the market with these weird cut angles that are not ideal for optimum air flow and causes turbulence compared to the factory "J" pipe. The factory "J" pipe is a form molded plastic piece. Thus, we form mold casted our "J" pipe out of 6061 aluminum for the ideal flow just like factory. Often ignored, charged intake airflow characteristics greatly affect throttle response, turbo lag and ultimately maximum power potential. Smooth bends and minimal obstructions are ideal.
The factory S55 "J" is secured to the throttle body with a plastic retainer strip. We did not feel confident this plastic retainer clip was going to hold up against high boost so we converted the connection to accept a metal C clip (included in our kit). Once you remove the factory plastic retaining clip, you will understand why we changed it.
1/8" NPT Bungs (For Methanol or Nitrous Injectors):
With the popularity of methanol injection systems and nitrous systems, our charge pipe come with a 1/8" NPT threaded bung (for methanol or nos injectors) on our "J" charge pipe. This allows quick and easy installation of methanol/nitrous injectors that are used in methanol injection systems and nitrous systems. Each 1/8" NPT bung will come with a plug so that you can run with or without the methanol injector. This is perfect for those who do not have the Methanol Injection yet but plan to do so in the future.
Also, the 1/8" NPT bung can be used as a boost source (with the optional vacuum port fitting). Perfect place to connect your boost gauge or other devices to. The N55 engine does not have a pressurize hose or fitting from the factory that you can easily tap into. Now you do!
