PRL Motorsports Carbon Fiber Inlet Pipe Kit | Honda Civic 1.5T including Si 2016-2021

Product Overview

The PRL Motorsports Carbon Fiber Inlet Pipe Kit is designed for the 2016–2021 Honda Civic 1.5T platform, including Si trims. Engineered to reduce pre-turbo airflow restriction, the system improves turbocharger efficiency without requiring ECU recalibration. This kit integrates cast aluminum and thin-wall carbon fiber components to increase volume while preserving velocity, minimizing heat soak near the compressor inlet.

Tailored to Honda’s L15B7 engine architecture, this kit delivers refined throttle response and steady performance gains across the RPM range. It is specifically compatible with PRL Cobra Cold Air Intake and Short Ram Intake systems, and does not interfere with factory MAF readings.
