Maximize your FL5's engine intake system and turbocharger potential with the PRL Motorsports Turbocharger Inlet Pipe Kit. This kit is a direct bolt-on upgrade that eliminates intake airflow restriction before the turbocharger, allowing the turbocharger to operate more efficiently. Our design utilizes a cast aluminum inlet piece to allow smooth transition from the gasket-matched 64mm ID compressor inlet to a 80mm OD / 78mm ID outlet throughout the Titanium crossover pipe. This kit is the largest inlet pipe available and offers over a 50% increase in airflow volume in comparison to the factory inlet pipe! Increased bottom-end power and spool. Important Notes: NO ECU CALIBRATION REQUIRED ONLY COMPATIBLE WITH FACTORY AIR BOX
