Rivotto Clean Air Technology

We offer a suite of technologies collectively named Rivotto Clean Air Technology (RCAT). These proprietary technologies, which have been verified by independent labs, reduce fuel consumption by as much as 15% and emissions by up to 70%, depending on engine type. Each system can be used independently, or with additional RCAT systems to achieve even greater gains.

    Rivotto Guarantee on Manufacturer Warranty Maintenance

    OEM engine warranties do not apply to accessories which bear the name brand of another company, and will not warranty any RCAT part or result to the engine determined to be caused by RCAT products. If a user of any RCAT product files a warranty claim with the manufacturer for any covered warranty item on an engine or vehicle manufacturer’s warranty and the manufacturer attempts to deny that claim on account of an RCAT device installed, the terms of warranties available and reviewed by Rivotto provide that the manufacturer would have to prove that the failure or damage was caused by the RCAT product to be successful in holding their denied claim. No RCAT product is known to have ever been a suspected cause of a warranty claim on an engine or emissions system and has never been party to a denied warranty claim. Rivotto does carry product and garage keepers, general, and product liability insurance for the unlikely event that an engine warranty claim could arise and a manufacturer attempt to assign fault to an RCAT product.
