BG

CA$53.69

More Details
Main highlights
- Restores fuel economy
- Restores engine performance and improves drivability
- Increases power output
- Gasoline quality is inconsistent; And when gas at the pump varies in quality, the result is deposit buildup, inefficient ignition and combustion, and poor power output; To make matters worse, small, high output engines are extremely sensitive to deposits that build up on fuel injectors, intake ports, on intake valves and in combustion chambers; Even small amounts of deposits cause increased exhaust emissions, reduced fuel economy, drivability problems, and engine knock
