Mods to my 2016 Silverado 1500 Z71

[mmessuri]

So I am thinking of adding the following to my truck to improve the towing experience and I was wondering if anyone has already done so and what they think about it:

1. Range Technology Active Fuel Management Disable Device (Blue)
2. K&N Cold Air Intake Kit: High Performance
3. Some form of airbag suspension (could use a recommendation on which one).

Just to re-state what is in the title, my truck is a 2016 Silverado 1500 Z71 and I am towing a 2021 Cougar 26RBS.

Thanks.
