Weapon-R Secret Weapon Intake for BMW E46 3-Series 2000-2004, Performance Upgrade - 308-115-101

Weapon-R Secret Weapon Intake for BMW E46

If you're looking to give your BMW E46 a little extra oomph, the Secret Weapon Intake is a solid choice. This isn't just any intake; it's designed to boost the air intake volume to your engine like you wouldn't believe. How? It creates two distinct air velocity profiles—one zipping through at high speeds and the other taking a more leisurely route. This clever design means your engine gets fed up to three times more air than with a standard intake system. Yeah, you read that right.

The intake pipe is crafted from top-notch 6061 aluminum and shaped using an automated CNC mandrel bender, ensuring a precise fit that looks as good as it performs. Plus, it's polished to a mirror-like finish, so it’ll catch some eyes under the hood. The SW1 Air filter isn't just a pretty face either; it features a tuned velocity stack that ramps up air speed while keeping turbulence at bay. Right now, it’s available in a polished finish only, but honestly, that’s the way to go.

Key Features:

  • 1 Million Mile Limited Warranty—because we know you’ll love it.
  • Open pore high-density reusable foam filter—clean it, reuse it, and save some cash.
  • High-polished aluminum piping that looks as good as it performs.

This intake is a perfect fit for a range of BMW E46 models, including the 6-cylinder versions and the M3. Here’s a quick list of what it fits:

  • BMW 316i (1992-1998)
  • BMW 318i (1992-1998)
  • BMW 318is (1992-1999)

What is Weapon-R?

Weapon-R is a well-known manufacturer of aftermarket accessories for a number of popular makes and models. It is focused on performance products that will improve the power of your vehicle which, in turn, make the car an even greater joy to drive. Weapon-R parts are, oftentimes, considered to be some of the most unique, highest performing, and best looking in their class. With more than a decade of experience in building go-fast parts for speed demons, Weapon-R has garnered a respectable name of itself. Its products are popular among enthusiasts who crave effective performance without breaking the bank.

What Does Weapon-R Offer?

As aforementioned, Weapon-R is primarily known for its quality, high-performance intakes. At the forefront of its inventory is the Weapon-R cold air intake. The proper air intake will allow your engine to breathe better and get a lot more air at better temperatures. This, in turn, provides better fuel economy while also improving vehicle acceleration. Each individual Weapon-R part is built with a specific vehicle in mind and crafted from only the highest quality materials to ensure longevity and durability.

While Weapon-R is best known for its air intake kits, the brand has been building other performance-enhancing parts for many years. Its racing headers are a popular close second and have been well-received for some time now as an effective means to increase exhaust flow and provide notable horsepower and torque gains at an affordable price. 

Weapon-R’s lineup also includes intercooler pipe kits for an existing turbo and intercooler. This will help guarantee your turbo is receiving the coolest air possible, while attractive wider aluminum pipes allow for higher airflow.
