Fitment
| Years | Vehicle | Engine / application |
|---|---|---|
| 2019–2021 | Nissan Altima | 2.0L VC-Turbo only; not 2.5L |
Trim names such as Platinum and SR may also occur with other engines. The 2.0L turbo requirement applies independently of a saved trim match; those generic rows alone do not certify the engine.
