Fuel injectors sit in a very hostile environment and because of this they quickly become contaminated by carbon and other deposits.
BG fuel injector cleaners (recommended by Ford and GM in the USA) will restore injector atomisation and correct operation – reducing emissions, restoring fuel economy and restoring power.
Modern vehicles, like those with GDi, are finely tuned and extremely sensitive to deposits that build up in fuel injectors, intake valves and ports. Accumulated residues, mostly from fuel, can cause driveability problems such as: hesitation, misfire, stumble, poor MPG and performance loss.
BG Fuel Injection System Cleaner is especially effective with rock-hard fuel system deposits. As an integral part of the BG Fuel/Air Induction Service, it pre-soaks deposits which allows BG 44K® to provide an even more effective cleanup.
Although it’s a powerful professional-use product, BG Fuel Injection System Cleaner is not harmful to any fuel system components including gaskets, hoses, metals, fuel tank bladders, fuel pumps and O-rings.
