Product Description

The Weapon-R 301-133-101 Secret Weapon Intake is a performance short ram intake designed specifically for the 1986-1989 Honda Accord LXI and 1986-1991 Honda Prelude Si series. Built with a precision CNC mandrel-bent 6061 aluminum tube and a polished finish, this intake system increases airflow to the engine by creating dual air velocity paths. The result is improved throttle response, better induction sound, and potential power gains over the factory airbox setup.

Featuring a high-flow SW1 reusable foam air filter with a tuned velocity stack, the Weapon-R intake system enhances airspeed while reducing turbulence for more efficient combustion. Installation is straightforward with basic hand tools, requiring removal of the stock airbox and resonator. Note that this part is **not CARB-legal and is restricted from sale/use in California**. Enthusiasts looking for an easy bolt-on airflow upgrade for their classic Honda Accord or Prelude will appreciate the increased engine breathing and improved under-hood aesthetics this intake provides.
