It’s a simple swap either way. How long it takes will depend on what version you’re installing and what year your car is. If you have an early model, then you’ll have to deal with the factory bypass valve and wiring in the resistor for that bit if you have a newer car you’ll only have to deal with tapping the vacuum line for whatever blow off valve you got. If all you got was the plain charge pipe then that’s just a five minute swap.
