From O'Reilly Auto Parts' catalog — the store we buy your battery from (checked on a 2007 3.0L Z4). Some engines and trims differ, so we confirm the exact battery for your Z4 when you book and show you the price before we install it.
Where the battery is & what the swap involves
2003–2008 BMW Z4
Where it is: In the trunk.
After the swap: BMWs need the new battery registered with the car's computer so it charges it correctly — we do that as part of the swap.
How it works
Book online and pay the service fee — your card is saved. We head to your Z4, test the old battery, take it to the closest O'Reilly for the core exchange and buy the right new one at the store's walk-in price. Back at your car we charge the battery plus sales tax to your saved card, install it, test the charging system and email your receipt. Installation labor is covered for 90 days.
BMW Z4
Straight answers.
By O'Reilly's catalog, the BMW Z4 takes — 2003–2008: Group 48 or Group 47 (525–800 CCA). Engines can differ, so we confirm the exact battery for your Z4 when you book, and you see the price before we install it.
The catalog lists regular batteries for every BMW Z4 we cover; an AGM is an upgrade some owners choose for short trips and Oklahoma heat. For 2003–2008, regular and AGM both fit — we'll match what your Z4 came with unless you ask for the upgrade.
In the trunk. Wherever it is, we swap it where the car is parked.
