Product Description

The GReddy 12441000 compression tube is a performance-oriented upgrade designed specifically for the **1987-1992 Mazda RX-7 FC/FC3S** turbo platforms equipped with the 13B-T rotary engine. This rigid intercooler compression tube replaces the soft, factory-supplied rubber hose on the compression side of the intake tract between the turbocharger outlet and intercooler. By replacing flexible hoses with a rigid aluminum tube, airflow restrictiveness is reduced and throttle response can be improved under boost.

Constructed from durable aluminum with a polished finish, the GReddy compression tube enhances both performance and engine bay appearance. Its hard-pipe design minimizes flex and pressure loss that can occur with aging rubber hoses, helping ensure consistent airflow during demanding performance driving. A direct bolt-on solution tailored for the RX-7's turbo plumbing, this compression tube is a simple, lightweight upgrade for rotary enthusiasts looking to improve intake efficiency and reliability over stock components.
