You need a slim socket to change plugs on the 535. I know Assenmacher and Burger Motorsports have them, maybe others.
Cylinder 6 is tricky as it is below the upper strut support bar. Requires a swiveling ratchet head and universal joint on the extention. Otherwise straight forward.
Reason to replace them is to avoid misfires. Ignition coils also have a tendency to get worn out at 75-100k miles.
