The Mishimoto Silicone Inlet Pipe MISMMAI-CTR-23UBK is a direct-fit replacement inlet pipe for the 2023 and newer Honda Civic Type R (FL5), finished in black. It replaces the factory rubber inlet hose connecting the intercooler outlet to the throttle body with a high-temperature silicone construction that maintains shape under boost and engine bay heat cycling, reducing restriction and improving boost delivery consistency on the K20C1 turbocharged engine. The MISMMAI-CTR-23UBK includes all hardware for a direct bolt-on installation with no fabrication required.

The MISMMAI-CTR-23UBK is a Mishimoto black silicone inlet pipe for the 2023 and newer Honda Civic Type R FL5. It replaces the factory intercooler outlet-to-throttle body hose with high-temperature silicone to improve boost delivery and heat resistance on the K20C1 engine.
What is the difference between MISMMAI-CTR-23UBK and MISMMAI-CTR-23URD?The only difference is color. MISMMAI-CTR-23UBK is black and MISMMAI-CTR-23URD is red. Both are identical in construction, material, and fitment for the 2023+ FL5 Civic Type R.
Does the inlet pipe work with the factory intercooler and aftermarket intercoolers?MISMMAI-CTR-23UBK is designed for the factory intercooler outlet. Compatibility with an aftermarket intercooler depends on whether the aftermarket unit uses the same outlet dimensions and position. Confirm with the intercooler manufacturer before pairing.
Is MISMMAI-CTR-23UBK for FK8 or FL5?MISMMAI-CTR-23UBK is for the FL5 (2023+) Civic Type R only. FK8 owners need a different Mishimoto part number specific to their generation.
Will this inlet pipe increase boost levels?The silicone inlet pipe does not increase boost by itself. It reduces restriction and improves flow consistency, which can help the factory or upgraded turbo maintain more consistent boost delivery compared to a collapsing factory rubber hose.
Does MISMMAI-CTR-23UBK require cutting any factory components?No. MISMMAI-CTR-23UBK is a direct bolt-on replacement requiring no cutting, drilling, or permanent modification to the vehicle.
Is the black silicone finish durable in the FL5 engine bay?Yes. The high-temperature silicone construction is rated for sustained engine bay temperatures. The black color is consistent and UV-stable under normal driving conditions.
How long does installation take?Typical installation time for MISMMAI-CTR-23UBK is 20 to 40 minutes with basic hand tools and no special equipment required.
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...

A turbo inlet pipe connects the air filter or airbox to the compressor inlet of the turbocharger, providing the unrestricted airflow path the compressor needs to spool efficiently. Upgrading from a corrugated OEM rubber inlet to a smooth-bore silicone or aluminum replacement reduces restriction and turbulence at the compressor inlet, which can improve spool response and reduce inlet restriction losses at high boost. Popular Turbo Inlet Pipe Options Popular turbo inlet pipe upgrades include smooth-bore silicone inlet hoses with integrally molded reducer sections for platforms with restrictive factory accordion inlets, mandrel-bent aluminum or stainless inlet pipes for custom air filter relocation, and larger-diameter reinforced silicone inlets for high-horsepower builds where the factory inlet diameter becomes a restriction. Popular platforms with well-supported turbo inlet upgrades include the Subaru WRX, Ford Focus ST and RS, Volkswagen GTI and Golf R, and BMW turbocharged inline-f...
