E63 Spark Plugs Upgrade over Stock NGK
Is the a better plug for the M156 I can install that is better the the OEM NGK.
I have headers and 2 3/4 piping to the resonator. All cats are gone.
I have KNNs and the intake mod along with a Tune.
I saw Weistec list some but that is for the added SC upgrade.
