Bro, seriously how many bottle do I need to FULLY clean up the carbon in combustion chamber for car mileage over 15xxxx km? Coz I dont think 1 bottle is enough.
heres the how to on the ones me and my cuzn did...
we did these on his Almera Gti but this can be done any lights..
Gave it try was realtively easy to be fair
It took about 15min to do the fog lights...
