RIVA Yamaha TR-1 Intake Manifold Upgrade Kit

Our Intake Manifold Upgrade Kit enables your TR-1 naturally aspirated engine to produce more horsepower by delivering increased air flow. Precision machined billet sleeve directly replaces restrictive mesh element in OEM plastic intake manifold. Provides improved low end punch and mid-range pull. Includes special tools & detailed installation instructions. Requires installation of RIVA Replacement Performance Air Filter to meet U.S. Coast Guard certified flame arrestor requirements.
