Oil Separator kit - N63

Product Details

In high output BMW engines like the N63 and S63 4.4L V8, maintaining precise crankcase pressure dynamics isn't just about emissions it's also vital for engine health and peak performance. The "Hot-V" layout exposes crankcase breather hoses to extreme thermal stress, leading to hardened and cracked plastic lines that bleed off vacuum and compromise power delivery.

If your BMW is burning oil, showing unmetered air faults, or suffering from degraded throttle response, a compromised breather system is usually the culprit.

The N63 Crankcase Breather Package pairs Genuine BMW oil separators with OE tier Rein connecting pipes. Designed to restore factory level oil separation and sealed vacuum integrity across both cylinder banks
