Tell your dad that he doesn't know what he's doing.
I'll assume he wants to do a cold air intake.
In which case, tell him to look at the car's engine, as it already HAS a cold air intake.
The intake leads away from the hot air of the engine, to the cold air near the front of the car.
That's the definition of a cold air intake.
An aftermarket one won't mess with the computer, because the difference is so incredibly marginal, that it makes no difference at all.
At best, 1-2 horsepower.
Complete waste of money, since he's not giving the car anything it doesn't already have.
It won't be faster, it won't get better gas mileage.
