Weapon-R Secret Weapon Intake System for 2009-2014 Acura TL 3.5L V6 and 3.7L V6 Engines
The Weapon-R Secret Weapon Intake System, engineered specifically for the 2009-2014 Acura TL models equipped with 3.5L or 3.7L V6 engines. This intake system stands out by delivering three times the air volume and mass compared to standard stock setups, thanks to its innovative design that leverages the Coanda effect and Bernoulli's principle. These physics-based principles create dual air velocity profiles within the intake tube one fast-moving stream along the inner wall and a slower core stream resulting in smoother airflow, reduced turbulence, and more efficient engine breathing. Independent testing by Tuner Performance Reports Magazine in their Intake System Showdown confirmed this system's lead over traditional cold air intakes and short ram intakes, providing measurable gains in horsepower, torque, acceleration, and throttle response while adding an aggressive engine note.
Precise Vehicle Fitment
This intake kit fits the following vehicles without modifications:
- 2009-2014 Acura TL Base (3.5L V6)
- 2009-2014 Acura TL SH-AWD (3.7L V6)
Part number: 301-165-101. Backed by US Patent #7,263,961B2 and a limited 1-million-mile warranty for long-term reliability.

What This Category Covers An air intake system pulls outside air into the engine and filters it before combustion. Upgrading the factory intake with a cold air intake, short ram intake, or carbon fiber system can improve airflow, throttle response, induction sound, and horsepower potential on compatible applications. Cold Air Intakes vs Short Ram Intakes Cold air intakes route the filter away from engine bay heat for cooler, de...
