Reduces carbon build up on spark plugs and injectors on turbo direct injection engines. Far superior to over the counter brands. Less spark plug and coils changes!

Good staff for my 335i N54

I used this as well as the engine flush and mos2 anti-friction from liquimoly during my last oil change and since then my car has felt much smoother, sounds smoother, and I gained about 3mpg. I absolutely recommend using this trifecta on any used car you buy.

Liqui Moly products are awesome! Have been using for over 20 years.

Helped me to reduce minor shuddering at higher speeds due to older fuel injectors!

Works well. Use it at about every oil change. Maybe a little more if I’m feeling froggy.

Used this and my car cone to life again. Enhanced mpg by 8! I use this every third fillup now on both my German machines!

It might be a placebo but I feel like it does something. Cheap insurance between valve cleanings.

Use in all my cars great stuff definitely works Great price! M235i - M3 E92 - M5 E60 - A4 B6

Works as intended.
