The R&D Power Core Intake Manifold Sleeve Kit was developed to increase airflow into and through the intake system by relieving restriction. The R&D Intake Manifold Sleeve replaces the OEM intake ribbon producing a 40 CFM increase in air flow. The R&D billet sleeve mounts between the intake manifold and the throttle body creating a superior Venturi effect. The R&D Intake Kit will add low end and mid range throttle response, and a full 100 plus rpms to top end performance to a stock SVHO. The R&D Intake sleeve is an absolute must have part to remove intake restrictions before contemplating power adding compressor booster wheels or turbo charger kits to the Yamaha SVHO engine. True horsepower gains on the Yamaha start right here with the R&D Intake Sleeve. More airflow will equal more power. R&D recommends upgrading the Cooling System with R&D Cooling Kit Pt. # 660-18002 and Intercooler Pt. # 612-18006 or 612-18005 for added air flow and power. * Picture displays restictive OEM ribbon (left), R&D Sleeve (center), and R&D Sleeve with OEM Seal (right). Available from R&D with Pt. # 612-17997.

It makes the difference when you build a 440/550/650 hull with a bigger engine in it. It releases the power from the engine and makes the throttle response crispier. Side Exhaust Exit, 1 - 3/4". Could be used on 440, 550, 650sx, X-2, and others. $25 + s&h. For more information contact John at watcon@watcon.com

The R&D High Performance Power Plenum Air Filter Kit was designed and developed exclusively for the Kawasaki 15F/12F intake system. The R&D filter kit will unleash low-end, mid-range, and peak horsepower trapped in the restrictive stock air box. The exclusive lightweight filter design couples to the OEM throttle body, and is engineered with a large plenum to deliver massive cubic air volume and improved air speed. Dyno tested and championships proven, Power Plenum Filters generate the maximum airflow and volume. Replacing the O.E.M. air box with the R&D Filter kit offers an economical way to improve performance, looks, and sound. Kit comes complete with all necessary hardware.

R&D Performance Products, U.S.A. announces the release of the new R&D Powershot fuel injection tunning module and fuel controller. The R&D Powershot fuel injection tuner will deliver increased horsepower, acceleration, and stronger mid-range performance by delivering a higher performing air to fuel ratio (A.F.R.) to the engine. Many of today’s high performance fuel injected four stroke muscle craft have a lean A.F.R. R&D Performance has tested, documented, and analyzed the O.E.M. fuel maps on every current fuel injected four stroke watercraft, and pre-programmed and coded the new R&D Powershot fuel injection control module to safely alter the O.E.M. fuel map to a higher performing and safer A.F.R. (richer). More horsepower, greater acceleration and stronger mid-range are the result when the proper A.F.R. is achieved and is tuned for optimum performance. The R&D Powershot is fully adjustable on the fly (with the engine running, observed and tuned while riding), and will accommodate a wide range of adjustability to properly performance tune the A.F.R. for any combination of aftermarket parts. The R&D Powershot will add horsepower, reliability, and adjustability to any electronic fuel injected two or four stroke watercraft engine. R&D has a Powershot unit for virtually every watercraft application! Available for all two and four stroke fuel injected SeaDoo, Yamaha, Kawasaki, and Honda watercraft. The R&D Powershot is a must have part on supercharged SeaDoos using new vortech performance high boost compressor wheels, and Kawasaki 15Fs with offshore kits! Recommended for For competition use only. It is available from R&D with part number Pt. # 801-15000
