Weapon R - Performance Intake Systems, Catch Cans, Chassis Accessories, & More

Founded in 1993 with roots in Asia and the U.S., Weapon R Competition Products specializes in vehicle-specific performance parts such as Secret Weapon and Dragon intake systems, catch cans, exhaust components, chassis braces, and engine torque dampers. Their California‑based R&D team designs each product for fitment, airflow optimization, and ease of installation—resulting in bolt-on solutions praised by DIY tuners and weekend racers.

Popular over a wide range of models—from Honda Civics, TSX, and 350Zs to Camrys and Chargers—Weapon R intakes include both Short Ram “Dragon” and full Cold Air “Secret Weapon” kits, engineered for horsepower gains and tuning responsiveness. They also offer handy accessories like oil/coolant catch cans and torque dampers. Enthusiasts appreciate their balance of price, quality, and U.S.-based customer service—though some report sound and heat-soak trade-offs compared to higher-end brands.

Whether you're building a street tuner or weekend track car, Weapon R delivers accessible, performance-focused gear engineered to deliver real-world results.
