Subaru Legacy Parts

Everything Crawford Performance makes for the Subaru Legacy: Air Oil Separators for the Legacy GT (2005-2009) and the 2.5 (2013-2019), and Billet Power Blocks for 2013-2014. Part of the Baja family line — Crosstrek, Forester, Outback, and Ascent — built to the standard of our factory desert racing program.

Built in-house

Engines assembled at our East Coast facility. Parts designed, tested, and proven on our own cars — including the Gymkhana builds.

Support from the builders

Questions go to the people who made the part, not a call center. Contact us — a real person answers.
