Newbie DIY guy here thinking about replacing my own spark plugs and coils, which I have never done on this car (I've replaced the coils in my A4 before but that seemed a lot easier; the V8 kinda scares me)
My local shop said it would cost me around $500 just for the plugs and I'm getting misfire codes on cylinders 4 and 5. I'm also seeing error codes 17887, 17819 and 17831 - all related to the secondary air injection problems but that's an issue for another day. I think I'm just going to replace the coils and plugs all at once, seems logical.
So for the rook DIY'er, I had a few questions:
1. Would you guys recommend trying to replace plugs and coils yourself or is it a huge project left for professionals? (I'm pretty handy and would love some thoughts before I get started. I've read it's super easy but that's all relative)
2. Are these the tools/equipment I would need?

3. Am I missing anything else? How long should this take?
Thanks a lot!
