BG 44K® Power Enhancer® safely, rapidly and thoroughly removes engine deposits in combustion chambers, intake manifolds, ports and on valves. It restores flow in fuel injectors and cleans the entire fuel system. BG 44K® Power Enhancer® improves fuel economy and reduces exhaust emissions. It actually restores that “like new” driveability to an engine’s performance and keeps it running better, longer and more efficiently. We recommend it with major services, and as preventative maintenance.
