Can I use this on my intercooler without damaging the fins?

The brush is designed for grille and radiator cleaning, so it's built for fin work. Start on a lower speed or test on a small section first to confirm the bristle stiffness works for your specific intercooler core.

Is this brush head replaceable if it wears out?

Brush head replacement availability not specified. Check if refill heads are sold separately before relying on this tool for long-term use.
