An auxiliary valve assembly for improving the aspiration of an internal combustion engine. The auxiliary valve can be thread-mounted to a gas-air intake chamber. A spring-biased ball that seals an air inlet opens under sufficient vacuum pressure. Filtered air then passes through the auxiliary valve assembly into the gas-air intake chamber. The incoming air oxygenates the gas and thus improves fuel economy, extends value and spark plug life, reduces pollution, and improves oil viscosity.
