Denso Iridium IK20 vs NGK IX Iridium BKR6EIX,
Which one will be the best for our Lo-tuned Bimmers?
If changing the power cables and coils as well,
will there be any help or change for the performance on the cars?
For e.g. NGK Power Cable, Nology's Hotwires and Nology's Power Core.
Guys, please advice something on these,
Thanks in advance!
