I purchased a Riva Racing performance intake grate for my RXP-X and never installed it. Brand new, retails for $149.95 plus shipping and this is a deal for pick up at $120 cash in Olympia, WA

From Riva Racing: This top-loader intake grate features a unique tapered wing design that eliminates prop spin and cavitation while delivering enhanced acceleration and 2mph additional top-speed. Deep side rails improve stability and handling. Durable black race coating protects from corrosion. Race Legal. Fits all RXP-X & RXT-X models.
