Fitment & Compatibility:

This breather fits ALL B58 vehicles that use the most common oil fill cap design. However, not all BMW models use the same oil cap, so please verify your fitment.

📌 How to Check Your Fitment:

⚠️ Important Notes:

🔹 Hood Clearance Considerations

• Not all B58 models have the same hood clearance.
• We cannot guarantee fitment on untested models, so please test hood clearance carefully before fully closing it.
• If the breather does not fit, contact us for a return and refund.

✅ Verified Fitment with No Clearance Issues: BMW 340i

🔹 Maintenance Advisory

• This is a service item—it captures oil from spent gases, so it must be cleaned periodically.
• Vehicles with high crankcase pressure may require more frequent cleaning to prevent oil mist from escaping.
