5.3 gmc Sierra 2015 first mods ?

Volant cold air intake
also 1994vmax has a great point, a catch can is a great idea also. Both are very simple to install with basic hand tools.
I would do these and if you can exhaust then get your tune done. No sense is paying for a tune on a stock truck when your buying mods.
