4oz of B12 in each cylinder let sit for 24hrs then blow it out and use copper plugs because it has more surface area for the spark and easier starting. then drive it for 20-30mins and change oil did it to a k series and no issues its been 2 weeks
@@litelu0426 these plugs were just put in till he found a buyer. Even if I had installed the laser platinum, those plugs would had fouled up within the same week.
Mix in some light oil, like MMO to get the deposits to detach and soften. Valvoline has a new product to clean the oil control rings from below.... An intake spray like CRC will help the valves as well as rings. Otherwise, soak, spray whatever, these engines need top end cleaning.

I put Denso IK20 for my 2012 Q5, IK22 may be too cold and get more carbon buildup
