Weapon-R 307-170-101 Secret Weapon Cold Air Intake Kit - Polished 3.5

The Weapon-R 307-170-101 Secret Weapon Intake is a high-performance cold air intake system engineered to significantly increase airflow volume and velocity to the engine. Using Weapon-R's proprietary dual-velocity-profile technology, the system generates two distinct air velocity streams — one moving at a higher speed than the other — working together to deliver up to 3x more air to the engine compared to a conventional factory intake system.

Key Features:

• Intake pipe precision-bent from aircraft-grade 6061 aluminum using an automated CNC mandrel bender for consistent, smooth bends with no flow restrictions
• High-gloss polished finish — show-quality appearance straight out of the box
• Includes the SW1 conical air filter with a tuned velocity stack designed to maximize air velocity and minimize turbulence at the filter inlet
• Open-pore, high-density reusable foam filter media — washable and reusable for long-term cost savings
• 3.5" inlet diameter (NSWP version) for optimized flow on compatible engines
• Available in polished finish only
• Backed by Weapon-R's 1 Million Mile Limited Warranty

The Secret Weapon Intake is part of Weapon-R's extensive lineup covering over 250 applications across cars, trucks, and SUVs. The combination of CNC-precision construction, reusable filtration, and dual-velocity airflow technology makes this intake a strong performance and value upgrade over the stock air intake system.
