The Edelbrock Signature Series Round Air Cleaner is a new style with a shape reminiscent of the muscle car era. The Edelbrock signature and styling coordinate beautifully with the Edelbrock Signature Series valve covers. This offers superior flow capacity, low profile, good filtration, performance benefits and long term savings with the popular reusable air filter. Tests prove Pro-Flo air cleaners have low air restriction and good breathing ability for better performance. This air cleaner is an economical and effective way to keep clean air feeding for the engine without the expense of a new filter every few thousand miles.
