Engineered specifically for the Yamaha 1.8-liter naturally aspirated engine, this RIVA intake manifold upgrade kit optimizes performance by replacing the restrictive stock mesh element with a precision-tapered billet sleeve. This design modification facilitates increased air flow, resulting in measurable gains in horsepower, low-end punch, and mid-range pull. RIVA testing confirms that the stock ECU automatically compensates for the enhanced airflow, ensuring the system operates seamlessly without requiring additional tuning.
Installation is designed to be quick and easy, making it a straightforward upgrade for performance-focused riders. It is critical to note that this kit requires a Coast Guard-approved aftermarket filter kit to satisfy flame arrestor requirements. These components are strictly designated for closed-course competition use only; operation on public lands or waterways within the state of California is illegal.
