Performance upgrade

Hello all, looking for some advice here. I have a 2001 Grand Cher. Limited 4.7 liter. Iam looking to add some minor upgrades that will give me some extra power (that i will notice). I have heard that I might not notice a new intake. What are some other options I have with out doing something to void my warranty.

Thanks

water and mud will effect it, although you could make a water sheild, basically sealing it off from the bottom side

if you do a lot of mudding and water crossings, id reccomend just a replacement air filter
