Canonical URL: https://miatatorque.com/spec/idle-up-power-steering-mt-nb2/

Applicability: NB 2001–2005 (BP-Z3, 5MT/6MT) — Other years inferred within NB2 non-turbo family from actual 2003/2005 factory evidence.; NB 2004–2005 (BP-Z3-TURBO, 6MT) — Actual2005 factory evidence; 2004 inferred within MSM family.

Confidence: fsm

750–850 rpm (800 ± 50 rpm)

Always confirm against your factory manual. Match every restriction and follow all stages and procedure notes. Disputed claims must not be automatically resolved. The complete record below preserves every printed unit, source claim and procedure.
