Sory guys...but all these spark plugs on this page...don't look good !
That's why i change mine on 20K miles,but here in Belgium i run alway's 98 RON !
So...maybe therefore my plugs looks way better,and keep in mind...the S65 likes new plugs
When i changed my plugs...i felt realy the difference,so you guys with plugs in a realy bad condition...you must even more feeling the difference
