  • The R&D Power Plenum Breather Kits unique design will flow much more air than the O.E.M. filter. O.E.M. filters are notorious for becoming over oil saturated causing sluggish low-end power and a loss of up to 500 RPMs! The R&D replacement breather will never become over oil saturated, making it the only replacement choice! Easy to install in 5 minutes, adds a great sound tone, and adds RPMs.

  • The R&D FX H/O Power Plenum Filter Kit will add low end and mid range performance to the Yamaha FX H/O by replacing the restrictive flame arrester system with a high flow, high velocity air filter/velocity stack design combination! R&D Performance filters have been dyno tested on 4-stroke watercraft engines to in excess of 300 H.P.! R&D Power Plenum Filter Kits install quickly and easily, and add a great high performance sound to the Yamaha FX H/O!

  • The R&D Yamaha FX H/O Aquavein Intake Grate has been in the design, development and testing stages for 2 years! The new R&D FX H/O Aquavein will significantly reduce cavitation, increase acceleration, add up to 1 mph on top end performance, and keep the H.O. pump loaded and hooked up! Works great on aftermarket supercharged models as well.
