The PRL 4847RS Drop-In Turbocharger Upgrade is designed for 2016-2021 Civic 1.5T owners who want significantly more power without sacrificing the quick response and drivability that make these cars enjoyable to drive. Built as a true drop-in replacement for the factory turbocharger, the 4847RS installs without modifications and retains OEM-style fitment. The "RS" designation stands for Rapid Spool, reflecting the primary design goal: stock-like spool characteristics while supporting substantially greater airflow and power potential.

At the heart of the 4847RS is a carefully selected combination of advanced materials and modern turbocharger technology. A 7075 point-milled compressor wheel, Inconel turbine wheel assembly, and Si3N4 ceramic bearing system work together to deliver exceptional response, durability, and long-term reliability under demanding conditions. Whether you're chasing improved performance on a daily-driven Civic or building a more capable street and track package, the 4847RS offers a strong balance of responsiveness, power capability, and reliability.
