Product Details

The Weapon-R 302-128-109 Secret Weapon Intake is a high-performance cold air intake system engineered to maximize airflow volume and velocity to your engine. Part of the Stealth Series, this intake features a sleek black finish designed to complement underhood aesthetics while delivering serious performance gains.

Weapon-R's patented Secret Weapon induction technology (USA Patent #7,263,961B2) works by creating two distinct air velocity profiles simultaneously — one traveling at a significantly higher speed than the other. This dual-profile approach increases both air volume and charge speed, delivering up to 3x more air induction than a conventional OEM air intake system.

Key Features:

  • Intake pipe precision-bent from high-quality 6061 aluminum using an automated CNC mandrel bender for consistent quality and smooth airflow
  • SW1 Air Filter with tuned velocity stack to maximize air velocity while reducing turbulence
  • Open-pore, high-density reusable foam filter element — washable and re-oilable for long service life
  • Stealth Series black finish for a clean, aggressive underhood appearance
  • 1 Million Mile Limited Warranty for long-term peace of mind
  • USA Patented technology (Patent #7,263,961B2)
  • Available across 250+ applications for cars, trucks, and SUVs

The Weapon-R Secret Weapon Intake is a direct-fit performance upgrade that replaces the restrictive factory air intake system, improving throttle response, engine sound, and overall engine breathing efficiency. Professional installation is recommended.

Autoplicity so far has been great place to buy online automotive stuff. Good prices and well organized.

best prices ever expect more money from me started seeing other great deals! yeeee muh fuga

Great prices

I looked all over the web for the Thule sidekick car top carrier and autoplicity had the best price and the website was easy to maneuver through. It willbe my first stop for shopping.

It was easy to order and the truck bed extender we bought was the lowest price we could find! However, the shipping charge was higher than what was posted on the comparison sight. Nevertheless, it still came in under the next highest price from a different vendor.

Easy

Great Pricing with Free Shipping, easy to shop and navigate on the webpage
