Airspeed II Filter Adapter, from the manufacturer:
”
After extensive testing, 8 prototypes, over 200 dyno pulls on 3 different motors, up against every adapter that we could find, the AIRSPEED adapter has proven without a doubt, positive gains and a broader power curve on box stock class clone engines, specifically with top end “drop off” common with other adapters.
”
With the added air flow, the more rich main jet (.038) is mandatory for optimal engine performance. Works with all air filters that have a 2-7/16″ inlet.
