Engine Mods
I have a 17 Z06 A8. I want to add about 50 hp with bolt ons. I've seen Corsa X pipes and CAI's and Diablo tunes along with other mods. I want the items that work not the hype. I'm not looking to void the warranty
just to add a little more muscle. I appreciate the input from fellow owners. Thanks in advance.

What will you be using the car for? (Road course, 1/4 mile, canyons,....)
CAI without tune is not the best idea.
Tune will void powertrain warranty.
I don't think you can add power without risking warranty.
My 2 cents, the car has more power than anyone can use. I believe investment should go for secondary components to be able to get the most out the car.
DSC suspension or extra cooling (if the car used for performance driving) would be first upgrade.
If the car gets above certain temps, it's looses power. Adding extra HP will get you to power lossss sooner. In another word it's just a waste of money.

Honestly, if there was an easy 50hp on the table, GM would have done it. So you need to look at areas where GM was forced to compromise.
To find compromises, look at things forced on GM by commonality with the Stingray and/or forced upon them by the form factor.
That yields really two things, at least as far as I've learned: hood height and air cleaner. The hood is low enough that it compromised the intercooler, which was improved in 2017. The air cleaner is re-used from the Stingray and I don't think it flows enough for the LT4.
So, while I think adding an arbitrary 50hp is silly (why not pretend the car ships with 600hp and then you're already done!), I'd add a green air filter and be done with it.
Any serious mods are going to be the same thing - compromises in the exhaust system forced on them by emissions, for example. But then you're deep into warranty voiding.

The Halltech CAI does deliver. My 2015 Z06 did 604 rwhp with just the Halltech
intake. On a known Mustang dyno. VERY strong! My 2008 Z06 with a A&A kit with 9 psi with headers on the 427 never did that high. My car came in the shop with 7,000 miles on the Halltech and 14,000 on the car.
My tuner said He see at least 40 rwhp on everyone he installs.
I looking at getting one purchased as well for my 2017 A8.
I have 2 feelers out on used ones so I don't work for Halltech.
just his intake is the bomb!
They did leave 50 hp on the table.

Added an AFE CAI and Tony Mamo TB for approx. 55hp to my 2016 A8 Z06. Terrific, no codes, relatively low cost, and no warranty problems.
