Hi,
I just bought an 123-Tune for my standard MGRV8 3.9i with catalysts.
Which type of premium spark plugs would you recommend ?
I am thinking of Bosch 4 tipped plugs namely 4WR78 or of Iridium single fine tipped NGK BPR6EIX .
Cheers

Dear Mark,
Just for the record: the 123ignition does not need any special sparkplugs, you can use the same type/brand you have used before.
best regards,
