Does horsepower decrease as air filter restriction increases?

Horsepower

 

Dynamometer testing of horsepower at various filter restrictions has shown that horsepower remains constant as air filter restriction increases up to the maximum level of filter restriction recommended by engine and vehicle manufacturers.

Engine horsepower can decrease when air filter restriction exceeds the engine or vehicle manufacturer's recommendations.
