Garrett PowerMax Turbo Charger GTP38R Ford F250 7.3L 1999-2003

Description

Overview

The Garrett PowerMax GTP38R Turbocharger is the proven ball-bearing upgrade for the Ford F250 7.3L Powerstroke (1999–2003). It delivers faster spool, cooler EGTs, and significantly more airflow than stock thanks to an 88 mm GT compressor wheel and a 1.00 A/R turbine housing. This bolt-on kit includes the correct 4″ intake hose and required seals for a straightforward installation.
