About to do a full maintenance service as the car is at 70,000miles now.
Been running stage 2+ for a year now and previously was running stage 2 for a couple of years no hiccups. Always with stock plugs and 93 fueling.
Thinking of doing NGK plugs, what is best gap for them 0.020 or 0.022? and injectors, any recommendations on injectors or stock replacements are good enough?
BMW says dct fluid is lifetime but I ain’t cosy with that so going to replace that also.
