RIVA Intake Manifold Upgrade Kit for Yamaha GP and FX Cruiser HO/SHO Watercraft – Part RY12040-IMUK

Enhance your Yamaha watercraft's performance with the RIVA Intake Manifold Upgrade Kit designed specifically for models like the Yamaha GP 1800 and FX Cruiser HO/SHO series from 2011 to 2017. This high-quality upgrade features a precision tapered billet sleeve that directly replaces the restrictive mesh element in the stock intake manifold, allowing for increased airflow and improved engine performance. The result is enhanced horsepower, better low-end punch, and a more robust mid-range pull, giving you greater acceleration and responsiveness during watercraft operation.
The RIVA intake manifold is engineered for quick and straightforward installation, making it a popular choice among enthusiasts looking to optimize their watercraft without extensive modifications. RIVA testing confirms that the stock ECU will compensate for the increased airflow, ensuring reliable operation without the need for additional tuning. However, to meet flame arrestor requirements, this kit must be paired with a Coast Guard-approved aftermarket filter kit. These components are intended exclusively for closed course competition use and are not legal for use on public lands or waterways in California.
Constructed from durable materials, the intake manifold is designed to withstand demanding marine environments. Its precise engineering ensures a perfect fit for specified Yamaha models, delivering consistent performance gains. Whether you're racing or seeking to improve the overall responsiveness of your watercraft, this upgrade offers a reliable and effective solution to boost engine airflow and power output. Please note that installation should be performed by qualified technicians familiar with Yamaha watercraft systems to ensure optimal results and safety.
