My Cupra 280ST is getting a major service in the next few weeks and one thing getting replaced is the spark plugs.
The car is currently running about 370bhp with a number of mods, and alongside Millers Nanodrive NT+ 5w40 I would like to use upgraded spark plugs.
Does anyone know what ones are actually an improvement? I’ve seen posts about RS6/7 plugs etc but not sure exact what is required...
Any help would be massively appreciated.
