At least in theory, a better intercooler would definitely help you retain horsepower / torque in relatively high temps, particularly in either extended duration pulls or repeat short duration pulls. This would be a potential warranty buster. I think you’re less likely to have uncomfortable questions with a stock mount CAC. The front mount intercoolers are a huge “heavily modded” signal to anyone looking, especially techs with an axe to grind for whatever reason.
It will entirely depend on the individual’s working on the vehicle in the event you have a problem and the nature of the problem. If it’s the only mod, no tune, etc. and there’s some oddball powertrain issue, let’s say it’s a major one, like IDK... transmission or transfer case grenades. I think it would take a stretch of reality to relate an intercooler to that failure. But what if the engine ingested things it shouldn’t have? Yeah, that could well be on you.
I’ve seen some claims that a better intercooler actually nets more hp over stock. I haven’t seen any independent data to back that up.
A better intercooler would position you for future tuning or other mods like bigger turbos.
