Hi All,
Seen in many peoples signature they have replaced the plugs in their MK2 Leons.
Looks like the preferred choice is - NGK Iridium plugs.
1. What are the plugs fitted as standard on the Cupra?
2. Any noticeable performance gains, smoothness to be had replacing these / benefits?
3. NGK Iridium plugs the best?
Cheers
