First Power Mods for the WRX VB — In Order
Accessport, intake, j-pipe, tune — in that exact sequence. Skip the order, lose the gains.
Verdict
The fastest, cheapest path to real-world FA24 gains is a strict order — Accessport first, then intake, then j-pipe, then a proper e-tune; skip the order and you'll either leave power on the table or pay a tuner twice to clean up the mess.

Why the order matters
The FA24 is a sensitive platform. Every bolt-on changes airflow, boost response, or knock margin — and the ECU adapts to each one. Going out of order means either re-tuning multiple times (expensive) or running a mismatched OTS map (risky). The right sequence saves you money on tuning hours and protects your engine while you build.

What comes after step 4
Once the first four steps are done and your e-tune is settled, you're set up to add an intercooler, a catback, or supporting fuel mods without re-tuning from scratch. The custom map becomes your baseline — every future mod is a revision, not a rebuild.
Pre-purchase checks for this mod
- 1Confirm your platform: 2022+ WRX VB with the FA24 engine — do not order EJ or FA20 parts
- 2Budget for the entire sequence at the start, not step by step — Accessport + intake + j-pipe + e-tune is one project
- 3Locate a reputable e-tuner before you buy hardware that needs custom maps; lead times can run weeks
