Ditch the plastic and let your turbo breathe. The factory 2.4" OEM intake horn is a bottleneck that restricts the airflow your L5P needs to reach its full potential. We engineered our 3.5" Precision Machined Intake Horn to be a simple but high-impact upgrade, delivering a significant increase in airflow volume to the turbocharger.

This horn features a precision-machined anti-surge flange and a gradual taper down to the 3" turbo inlet, optimizing velocity while eliminating turbulence. Built to shop standards, it utilizes the factory O-ring for an OEM-grade seal and includes all new mounting hardware. Whether you’re looking for better throttle response, increased torque, or improved overall engine efficiency, this is the dialed-in fix for the L5P's restrictive intake tract.
