Turbochargers generate more than just boost. They generate a ton of incremental heat during operation, resulting in a "heat-soaked’ engine and eroded performance. So their power increase creates its own power decrease problem. Oops.

But an Active Autowerke BMW 335i methonalanol injection system will help chill the intake charge to a cooler temperature – effectively combating the heat soak effect. Additionally, the methonalanol-water mix increases your engine’s knock limit – thus serving as insurance against unwanted high boost detonation.

The methonalanol-water is precisely delivered and metered by its own electronic module. This module not only monitors the boost pressure within the engine but also controls the delivery flow to match both the engine load and demand as needed.

The large 1.8+ gallon reservoir is well suited for this task. The capacity is there to meet most demands; the trunk mounted location is ideal by being the furthest position away from both engine and exhaust heat; and its trunk position maximizes the trunk space. It has a rigid mount that's very secure, yet it can be easily detached if needed by its spring loaded quick releases.

If there’s one mod you should be considering for better forced induction performance, this is it. Take full advantage of the added safety provided by the Active Autowerke BMW 335i methonalanol Injection System with our off-road 335i Downpipe.

Key Features:

  • Trunk-mounted 1.8+ gallon reservoir with inline filter and low pickup tube
  • Reservoir location on Battery Tray maximizes trunk storage
  • methonalanol-water mix is not influenced by either engine or exhaust heat
  • Robust high volume pump will deliver on demand and is suited for a methonalanol-water mix
  • Electronic module delivers precisely. Settings can be re-adjusted if needed
  • Injection hose and wiring routed within a protective casing
  • NOT a generic, universal system but manufactured model specific
  • Detailed instruction with pictures makes for a simple install
  • Tested and proven on our 500+ HP turbo and supercharged cars


NOTE:

methonalanol or any liquid is not included with this system. The end user is responsible for procurement

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
