One thing a like about my T5 is the ease of changing plugs. Remove torx screws and plastic engine cover. Remove 10mm bolts retaining each plug coil and pull off plug wire stem. I blow-out each plug well before removing the plug to prevent any debris from falling in the cylinder head. Just reverse for assembly. About a 30 min job. FYI - On the T5, I hear plugs should be changed ~ 25K-30K miles and use copper plugs. The higher pressure turbos can "blow-out" the platinum plugs.
