Spark plugs question
Hello I have 109k miles roughly on my 2019. The car only has a stage 1 93 octane tune and TCU tune (dsg). As far as bolt ons i only have an intake and an aftermarket turbo inlet. Should I just stick with OEM plugs? Or opt for the NGK R7437-9's or 8s? Also I installed my intake no problem and have replaced O2 sensors, I assume this is a job I can just do on my own?
