Sure beats spending money on replacement injectors. This service guarantees the injectors will perform as new (hence the name ASNU) or better.
ALL fuel injectors can be brought back to new condition as long as the coil windings are not shorted inside. Injectors lose performance when deposits build up inside of the injector, which NO magical bottle treatment can remove. With this service I replace the internal filters which also get clogged up with deposits on injectors along with everything else pictured above.
If an injector has an issue and I can't fit it, you don't pay.
