HIGH ALTITUDE OPERATION
Operating an engine with standard air-fuel mixture at altitudes greater than 3,000 feet will result in a fuel-rich operating condition.
This can lead to increased fuel consumption, increased emissions, and the formation of carbon deposits on spark plugs that can
result in diculty starting engine. To ensure compliance with federal emission standards and avoid performance degradation,
engines must be tted with the appropriate altitude kit when operated at altitudes 3,000 feet or greater.
NOTICE:
1. Engines should not be operated at less than 3,000 feet when tted with an altitude kit. Doing so may result in serious damage
to engine.
2. Engines that have been modied with an altitude kit should only be operated at altitudes for which the kit is designed. Failure
to use the appropriate altitude kit at altitudes in excess of 3,000 feet may result in decreased engine performance, increased
fuel consumption and increased engine emissions.
3. Engine operation is not recommended in altitudes greater than 8,000 feet. Doing so will negatively aect engine performance.
4. For more information on obtaining an altitude kit visit www.GetEarthquake.com and reference your Parts Breakdown for
accurate part numbers. Installation of altitude kits should be performed by an authorized Viper service center only.
