2019+ - BMW G2X M340i, M440i with B58 engine

Active Autowerke is familiar with some of the issues that 2012 and newer N55 BMW 335i, 435i, M235i and M2 owners experience even running with the factory BMW boost. 

The BMW B58 utilizes an all plastic construction for the factory charge pipe.
This charge pipe will eventually break, although much better than the N55. Whenever the factory charge pipe break at the plastic seam, the engine immediately senses a huge vacuum leak where the engine ECU counters by sending the engine into LIMP MODE condition. Usually, the car's performance will feel diminished and lack luster as if running without a proper firing cylinder. 

The Active Autowerke B58 G-body Charge Pipe is a designated product designed from inception to cure and eliminate this problem on your BMW.
Constructed from all aluminum makes this charge pipe almost indestructible.
The connection to the throttle body is a CNC machined part to duplicate the factory fit as well making a tight, reliable seal. 

Owners of BMW with the B58 engine understands that additional power can be reliably maintained with the use of Water/Methanol injection as an added feature.


The Active Autowerke B58 Charge Pipe has a proper provision for this specific application. A boss with two separate ports are provided upstream where the injected mix of water/methanol can properly atomize before entering the engine. The thread depths for the water/methanol nozzles are also checked to allow for a proper spray pattern without hitting the inside walls of the threaded holes.

Key Features:
  • Specific design to correct a problem
  • Consistent diameter tubing for increased performance
  • Increased throttle response and decrease throttle lag
  • CNC machined throttle housing for a proper seal
  • Retains factory BMW O-Ring seal
  • Provision of raised boss for 2 Water/Methanol nozzles
  • BLACK powder coated for that OEM look
  • High quality silicone couplers and stainless clamps are included
    

NOTE:

The factory throttle clip and O-ring are not included with the B58 Charge Pipe

*NOT COMPATIBLE WITH XI MODELS*

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).
