TD04L-19T Turbo Upgrade for Subaru WRX, Forester XT & Saab 9-2X Aero
Mid-range performance turbocharger upgrade for 1998-2008 Subaru WRX, Forester XT 58T, and Saab 9-2X Aero. The TD04L-19T steps up airflow capacity over the stock TD04L-13T while retaining the same direct bolt-on fitment to factory EJ205/EJ255 manifolds and downpipes. The ideal upgrade for owners seeking more power without sacrificing low-end response.

TD04L-19T vs TD04L-13T vs TD04HL-19T — Which Should You Choose?
- TD04L-13T — Entry-level, near-stock spool. Best for lightly modified or daily-driven builds under 250 WHP.
- TD04L-19T (this product) — Mid-range step-up with larger inducer. More top-end flow than the 13T while retaining good low-end response. Ideal for 220–300 WHP builds.
- TD04HL-19T — Larger CHRA housing for higher peak airflow. Best for builds targeting 280–350 WHP with full supporting mods.
