    Final Product Design - E46 Intake Development, Part 3

    In our last update, we left you with some dyno results showing the potential this kit has for increased performance. Now that the development process is nearing completion, we have a finished and fully functional prototype to test fit onto a BMW 330i. This kit is a direct fit for the E46 330i and it includes a very straightforward component list and simple installation instructions. Let's jump into what our final kit looks like.

    As seen above, the multi-ply silicone intake hose features a CNC-machined connector for exact fitment onto our filter. The heat shield is made of black powder-coated steel to help keep the filter shielded from the engine bay heat. The weather stripping along the

  3. Stock Review + Initial Design - E46 Intake, Part 1

    Stock Review + Initial Design - E46 Intake, Part 1

    Our garage has been graced with the presence of a clean 2001 E46 330i, so we can now begin development on this E46 intake. Let's dive right in!

    Stock System

    The 330i stock intake system is similar to the 32X, the big difference being the size of the MAF housing. On the higher-output 330i models, this housing is larger so it can accept greater airflow needed by the more powerful, higher-displacement engine. To accommodate that larger diameter, our design will have a slightly enlarged opening on the heat shield. Everything else should fit right into place! Here are a few shots of the stock system we are working on.
