Description
The Mishimoto Turbo Inlet Pipe Kit (MMAI-CTR-23UBK) is a precision-cast aluminum replacement for the restrictive factory rubber inlet on the K20C1-powered Honda Civic Type R and Acura Integra Type S. Flow-bench testing confirms this forced induction upgrade cuts inlet restriction by 17.2% compared to the stock unit, giving the turbo a smoother, more direct path to draw air through.
Where the factory rubber inlet relies on abrupt bends that choke airflow before it ever reaches the turbo, this cast aluminum elbow reshapes the induction path with minimal turbulence and pressure drop. For owners chasing a more efficient forced induction system without touching tuning or cutting factory components, this turbo inlet pipe delivers a measurable, flow-bench-proven improvement in charge delivery and turbo response through the rev range. It’s a straightforward way to support the induction engine’s ability to breathe, and it’s offered in a powder coat black or red finish so the upgrade can either blend in or stand out under the hood.
Vehicle Applications
This turbo inlet pipe kit is a confirmed direct fit for the 2023-2026 Honda Civic Type R (chassis code FL5) and the 2024-2026 Acura Integra Type S (chassis code DE5), both equipped with the K20C1 engine. It mounts at the factory inlet location with no cutting, drilling, or additional modification required, making it a bolt-on addition to the factory induction system.
