Product Details

The Weapon-R Secret Weapon Intake is an innovative cold air intake system engineered to dramatically increase airflow volume to your engine. Unlike conventional intake systems, the Secret Weapon utilizes a unique dual-velocity technology that creates two distinct air velocity profiles—one traveling at higher speeds than the other. This patented design naturally feeds your engine up to three times more air than standard intake systems, resulting in improved throttle response, horsepower gains, and enhanced engine performance.

Premium Construction:

  • Intake pipe bent from high-quality 6061 aluminum using automated CNC mandrel bending for perfect, restriction-free bends
  • Polished to a show-quality mirror finish that looks as good as it performs
  • SW1 high-flow air filter features a tuned velocity stack to maximize air velocity while minimizing turbulence
  • Open-pore, high-density reusable foam filter element—washable and reusable for the life of your vehicle

Coverage and Warranty:

  • Available for over 250 applications covering cars, trucks, and SUVs
  • Backed by Weapon-R's 1 Million Mile Limited Warranty
  • Available in polished aluminum finish only

This complete air intake kit provides a straightforward performance upgrade that delivers real-world gains in power and efficiency while adding an eye-catching polished appearance under your hood.

great transaction, very fast shipping

easy to order

I've been looking for a deal on my parts all over the place for weeks until I came to autoplicity. Even places like ebay couldn't even compare. I saved $40 easily even with shipping and I'm getting the parts quiker then most would ship out. Thank you I will continue to do business here.<br>

good prices and amazon checkout a plus

So far, so good.

I was asked if the product I was purchasing was needed by a specific date in order to complete a project on time. Autoplicity responded and had the product to me a day earlier than I asked for without additional cost to me. I will order from them again.
