Weapon-R Secret Weapon Intake Kit for Mitsubishi Eclipse 2000-2005 4 & 6 Cylinders - 303-113-101

Weapon-R Secret Weapon Intake Kit Mitsubishi Eclipse 4 & 6 cyl 2000-2005 for 2000-2005 Mitsubishi Eclipse 303-113-101 | Vivid Racing

Alright, let’s talk about the Weapon-R Secret Weapon Intake. If you’re looking to boost your engine’s air intake without all the fluff, this is the real deal. It’s designed to ramp up the volume of air hitting your engine, creating two different air velocity profiles. One of them moves faster than the other, which means you get a serious increase in air flow—up to three times more than what you’d get from a stock intake system. Yeah, you heard that right.

Now, let’s get into the nitty-gritty. The intake pipe is crafted from high-quality 6061 aluminum and shaped using an automated CNC mandrel bender. This isn’t just some cheap knock-off; it’s polished to a show-quality finish that’ll make your engine bay look sharp. Plus, the SW1 air filter comes with a tuned velocity stack, which helps increase air speed while cutting down on turbulence. So, you can expect a smoother flow of air into your engine.

What’s even better? This intake is built to last, with a 1 Million Mile Limited Warranty. That’s right, you can count on it to hold up through the miles. The filter itself is made from open pore, high-density reusable foam, so you can clean it and keep it in top shape without needing to replace it every few months.

It fits a wide range of vehicles—over 250 applications for cars, trucks, and SUVs—thanks to its US Patent (# 7,263,961B2). Specifically, if you’ve got a Mitsubishi Eclipse from 2000 to 2005, whether it's a 4 or 6-cylinder, this intake is made for you.

Fitment:

  • Mitsubishi Eclipse 4 & 6 cyl 2000-2005

Note:

  • Keep in mind that the images are just for marketing purposes. The actual product may vary a bit.

So, if you’re ready to give your Eclipse a solid boost in performance, the Weapon-R Secret Weapon Intake is worth checking out. It’s practical, durable, and designed to make your ride a little more fun.

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.
