Yea i know lol. thanks. I recommend being extra careful while handling the plugs and make sure to torque the manifold perfectly if ever removing.

Did you code the car properly for the new injectors? You can just swap those out as they are flow balanced and the car needs to know their calibration.

My SA did it for me. For free too! So it's a win there!

My N55 misfired like hell when I changed my spark plugs 3 month ago. Make sure you have exactly the right ones, the new ones had a temperature rating just a little off and it idle'd like a tractor. Put the right ones in a week later and ran like a champ immediately.

Honestly I'm scared of doing a spark plug change, I'm at 88000km and last time they were changed was at 63,000km. Hopefully I don't get any problems after putting in the new ones.
