Product Description

The Injen FM1573I Front Mount Intercooler is a premium performance upgrade engineered specifically for the 10th generation Honda Civic 1.5L Turbo and Civic Si 1.5L Turbo models. Designed as a direct bolt-on replacement for the restrictive stock tube-and-fin intercooler, this high-efficiency bar-and-plate intercooler increases core volume by approximately 25 %, helping to dramatically improve charge air cooling under boost. Reducing intake temperatures by up to ~24 °F helps the turbocharged 1.5L engine maintain power during spirited driving and track use, translating into dyno-proven gains of up to ~16 hp and ~19 lb-ft of torque while retaining factory boost pressure across the core.

Constructed with precision TIG-welded aluminum and CAD-designed end tanks, the FM1573I ensures smooth airflow and reliable performance. The intercooler installs in about an hour using the factory intercooler piping and mounting locations, making it an ideal upgrade for both stock and modified vehicles. While it offers exceptional performance, note that this part is not CARB legal for sale or use in California and other CARB-regulated states. A limited lifetime warranty from Injen Technology backs the intercooler's craftsmanship and durability.
