GReddy Compression Tube for 1993-1996 Mazda RX-7 changes out factory intake tube with a hard, bigger, and polished compression tube. This tube helps increase airflow for better throttle response. Works with all Mazda RX-7 FD3S.
GReddy hard piping kits do not include any intercoolers. They are support items to either change the soft factory hoses to hard pipes or high capacity replacements that allow for rerouting. Universal kits are available for custom making intercooler compression pipes.
