Engineered to eliminate the flow restrictions of the stock intake tract, this Riva upgrade kit replaces the restrictive mesh element with a precision tapered billet sleeve. This design modification increases overall air flow, resulting in measurable gains in horsepower, improved low-end punch, and stronger mid-range pull. Riva testing confirms that the stock ECU automatically compensates for the increased air volume, ensuring the performance benefits are realized without requiring additional electronic tuning.
Installation is straightforward, though the kit mandates the use of an aftermarket power filter to satisfy U.S. Coast Guard certified flame arrestor requirements. It is critical to note that these components are designed exclusively for closed-course competition use. Operating this equipment on public lands or waterways within the state of California is strictly illegal.
