Weapon-R Secret Weapon Intake Kit for Mazda MP3 MP5 4 Cyl 2001-2003, Performance Upgrade - 302-121-101

If you're looking to give your Mazda MP3 or MP5 a serious boost in performance, the Weapon-R Secret Weapon Intake is where it’s at. This isn’t just another intake; it’s designed to really amp up the air intake volume to your engine. How? It cleverly creates two different air velocity profiles—one that’s zipping along at higher speeds and another that’s a bit slower. This means your engine gets fed a whopping three times more air than the usual stock intake system. Pretty cool, right?

The intake pipe is crafted from high-quality 6061 aluminum, and it’s bent using Weapon-R’s automated CNC mandrel bender. You’ll appreciate the polished finish—it’s not just for looks; it’s built to last. Plus, the SW1 Air filter features a tuned velocity stack that ramps up the air velocity while cutting down on turbulence. It’s all about getting that smooth, efficient airflow into your engine.

And hey, this isn’t some flimsy part. It comes with a 1 Million Mile Limited Warranty, so you know it’s built to withstand the test of time. The open pore high-density reusable foam filter means you can clean it and keep using it for ages. With over 250 applications for cars, trucks, and SUVs, this intake is a solid choice for a variety of setups (and yes, it’s backed by a USA patent, #7,263,961B2).

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.
