Mishimoto MMAI-CTR-23UBK Turbo Inlet Pipe Upgrade Kit Black

The Mishimoto MMAI-CTR-23UBK is a performance turbo inlet pipe upgrade kit engineered for the 2023+ Honda Civic Type R (FL5). Developed using CAD modeling, 3D printing, and flow bench testing, this kit replaces the factory turbo inlet pipe with a larger-diameter, less-restrictive pathway that feeds the K20C1 turbocharger more efficiently — improving spool response and pre-turbo airflow.

The inlet pipe is constructed from a precision CNC-machined cast-aluminum turbo compressor inlet connection mated to mandrel-bent aluminum tubing, professionally TIG welded for a seamless, durable assembly. The cast lower flange is designed to OEM specifications for a perfect bolt-on fit. This kit is finished in a durable black powder coat for a clean, aggressive look in the engine bay.

Key Features:

• Precision CNC-machined cast-aluminum turbo inlet connection flange
• Mandrel-bent aluminum upper tube TIG welded to cast lower
• Larger internal diameter reduces pre-turbo air restriction and improves turbo spool
• Less restrictive than the OEM turbo inlet pipe
• Black powder-coated finish for a stealth engine bay appearance
• Includes 4-ply silicone inlet coupler, stainless steel worm-gear clamps, and EVAP hose adapter flange
• Bolt-on installation — no cutting or modification required
• Backed by the Mishimoto Lifetime Warranty

• (1) Aluminum Turbocharger Inlet Pipe
• (1) Silicone Inlet Hose Adapter (4-ply)

The Mishimoto MMAI-CTR-23UBK turbo inlet upgrade is an ideal first step in maximizing induction performance on the FL5 Civic Type R, and its benefits compound as additional intake and forced induction upgrades are made. As with all Mishimoto products, it is covered by the Mishimoto Lifetime Warranty.
