Weapon-R 4" Inlet 6.5" Tall 6.5" Wide SW Air Filter for Universal Fitment - 710-111-102

If you're looking to give your engine a serious boost, the Secret Weapon Air Filter is where it's at. This isn't just another air filter; it’s the result of countless hours spent on testing and tuning airflow dynamics. With a 4-inch inlet and dimensions of 6.5 inches tall and wide, this filter is designed to maximize airflow while keeping your engine protected.

What sets this filter apart? For starters, it’s crafted from high-quality dense Poly Urethane Foam, which means it’s built to last. In fact, studies have shown that this foam filter can deliver flow rates that are up to 80% better than your standard cotton filters. That’s a game-changer for anyone who wants their engine to breathe better. The secret sauce here is the CAD-designed and flow-bench tested velocity stack. This clever design not only increases airflow but also boosts airspeed and air mass, leading to noticeable improvements in engine performance.

Another cool feature is how easy it is to maintain. You can disassemble the filter for cleaning, which is a huge plus. After cleaning the foam filtering element, just reassemble it, and you’re good to go. Plus, thanks to the Open Cell Technology Foam, this filter won’t clog up like others do. Even when it gets dirty, it still allows for great airflow, so you don’t have to worry about sacrificing performance.

This filter is universal, so it’ll fit a variety of setups, and it comes in different inlet sizes and lengths to match your specific needs. Just keep in mind that the pictures you see are for marketing purposes, and the actual product may vary a bit.

In short, if you're serious about enhancing your engine's performance and want a reliable air filter that can handle the demands of your ride, the Weapon-R 4" Inlet 6.5" Tall 6.5" Wide SW Air Filter is definitely worth considering.

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.
