The S650 Mustang is a killer modern platform—but like every modern engine, it loves to yeet oil vapor straight back into the intake. That means carbon buildup, soggy throttle response, and your horsepower slowly walking out the back door. The SPE S650 External Catch Can Kit fixes it with a clean, chassis-specific setup that fits like OEM (but better), no hacky universal fittings needed. A high-capacity external can, proper PCV adapters, AN-style fittings, and an easy-access bracket keep blow-by where it belongs—not in your intake.
