The PRL Motorsports Titanium Turbocharger Inlet Pipe Kit for the L15B7 is a direct bolt-on upgrade that eliminates airflow restriction before the turbocharger, allowing the turbocharger to operate more efficiently. Thin-wall Titanium keeps helps reduce heat-soak. Our design utilizes a cast aluminum inlet piece to allow smooth transition from the gasket-matched 50mm ID compressor inlet to a 76.2mm OD / 74mm ID outlet throughout the Titanium crossover pipe. The compressor outlet diameter is increased to 45mm from the factory's 38mm diameter. This kit was designed to compliment Honda's 1.5L displacement perfectly by providing a significant increase in airflow volume in comparison to the factory inlet pipe, while maintaining velocity. A multi-piece design allows for easier installation and better fitment than a one-piece design.
