i would still recomend an intercooler. i had a charger on a corolla 4k motor as a rally car, it ran better with the cooler even though i was only pushing 7psi into it. its just an extra precaution so to speak. helps to prevent pinging. just remember ppl put cold air intake on newer cars for a reason, so why would you want to push hot air in when you could do something about it.
