Weapon-R Secret Weapon Intake Kit for Ford Explorer | Sport Trac 4.0L 6Cyl 2002-2004 - 307-138-101

Weapon-R Secret Weapon Intake Kit Ford Explorer | Sport Trac 4.0l 6Cyl 2002-2004 for 2002-2004 Ford Explorer 307-138-101 | Vivid Racing

If you’re looking to boost your engine's breathing without getting too fancy, the Secret Weapon Intake is worth a look. It’s all about getting more air into your engine, and this kit does that by creating two different air velocity profiles. One's moving faster than the other, which means you’re getting a solid increase in air volume and speed—up to three times more than your standard intake system. Pretty wild, right?

The intake pipe itself is crafted from high-quality 6061 Aluminum and bent using Weapon-R's automated CNC mandrel bender. It’s polished to a mirror-like finish, so it not only performs well but looks good while doing it. The included SW1 Air Filter features a tuned velocity stack that helps increase air speed and reduce turbulence. And yes, it only comes in that shiny polished finish, which really gives it a nice touch under the hood.

One of the best parts? You’ve got a 1 Million Mile Limited Warranty backing this thing up. Plus, it’s made with open pore high-density re-usable foam, so you’re not just throwing money away on a disposable filter. With over 250 applications for cars, trucks, and SUVs, this intake is no one-hit wonder. It’s patented too (USA PATENT # 7,263,961B2), so you know there’s some serious engineering behind it.

Fitment:

  • Ford Explorer | Sport Trac 4.0L 6Cyl (2002-2004)

So, if you’ve got a 2002-2004 Ford Explorer or Sport Trac with a 4.0L V6, this Weapon-R Secret Weapon Intake Kit (307-138-101) could be just what you need to give your ride a little more grunt. It’s all about that extra airflow, and trust me, your engine will thank you.

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.
