Collection: 4 Series
The BMW 4 Series is a line of compact executive cars manufactured and marketed by BMW since 2014. The 4 Series started in 2014 when BMW spun their 2-Door 3 Series Models off into their own line, and as such, the BMW 3 Series and 4 Series vehicles share the same engine and drivetrain configurations. To determine your 4 Series Chassis Code, please refer to the following:
| Model Years | Chassis Code |
| 2014 - 2020 | F32 / F33 / F36 |
| 2015 - 2019 | F82 / F83 |
| 2021 - | G22 / G23 / G26 |
| 2021 - | G82 / G83 |
