Til you have to pull the plugs on a 3v and they bust off. Oh and there's the cam phaser issue......
I swapped the plugs on mine when I installed the supercharger, I had to go a step colder on the plug. They all came out fine, one was a bit extra tight but a little releasing agent worked to loosen it up. You can break plugs in any car if you're a complete retard.
I've had zero issues with the motor in the 62,000 miles I've driven it.
