The 3.6-liter Pentastar is a solid engine, but from the factory it’s seriously choked by the intake. Hot air, restrictive tubing, zero personality. A proper cold air intake fixes that fast — better airflow, sharper throttle response, and that deep growl every Durango and Grand Cherokee owner secretly wants. If you’re ready to wake up your V Six without touching the internals, you’re in the right place.
