BG Fuel/Air Induction Service
Gasoline quality is inconsistent, and when gas at the pump is poor quality, it can cause 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 depoosits cause increased exhust emissions, reduces fuel economy, drivability problems and engine knock.
BG Air Intake System Cleaner (R) removes deposits that can accumulate in the air throttle body assemblies and plenums.
BG 44K (R) vanquishes deposits in combustion chambers, intake manifolds, ports and on valves and restores flow in fuel injectors.
