Audi B7 RS4 OEM Oil Cooler & Lines
Authentic OEM oil coolers and lines for the Audi B7 RS4 (2006–2008) with the 4.2L V8 engine are becoming more difficult to find new through official Audi dealers. A common issue on these vehicles is that the factory oil cooler can develop a leak over time. If you need to replace your oil cooler and lines, you will need to look for new old stock (NOS) or used OEM parts, or purchase an aftermarket replacement kit.
Used OEM parts
For those seeking a genuine OEM replacement, used parts from other owners are an option. Many used parts have been replaced for aftermarket upgrades, meaning they were still functional at the time of removal.
