The 3″ Inlet Pipe Kit for Mazdaspeed3 replaces one of the most overlooked bottlenecks in the entire factory intake tract — the pinched, pancake-style molded plastic inlet pipe that sits between the turbo compressor and MAF housing. Built for Mazdaspeed3 owners running a Garrett turbo upgrade or simply looking to unlock the airflow their stock turbo is capable of, this kit is engineered to eliminate the convoluted factory flowpath entirely. It’s the right choice for anyone serious about maximizing intake volume and boost response on the MS3 platform.

Performance & Application
This inlet pipe kit is designed specifically to handle the flow requirements of a big Garrett turbo upgrade on the Mazdaspeed3, while also improving flow on stock-turbo applications. By replacing the factory small-diameter, severely pinched entry with a smooth-transitioning 3″ pathway, the kit removes a major flow impediment that can hold back an otherwise capable turbo system from reaching its full power potential. The design accommodates significantly more volume than the factory piece across its entire length, translating to improved boost response and more complete power delivery.
