Fitment

Please Note: Exact AP3-SUB-007 manufacturer fitment: 2023-2026 Subaru Ascent, 2023-2025 Subaru Outback XT/Wilderness, and 2023-2025 Subaru Legacy XT/Sport, USDM CVT applications. The approved buckets are broader (2019-2025 Ascent, 2020-2025 Outback XT, and 2020-2025 Legacy), so the title and notes preserve the exact COBB year limits. 2026 Outback support is not confirmed.
