Audi & Porsche 4.0T V8 PCV Oil Separator Diaphragm – Repair Kit for PAB103495, 9A710349501 | Fits RS6, RS7, RSQ8, Cayenne, Panamera

Fix PCV Failure on Audi & Porsche 4.0T V8 Without Replacing the Entire Oil Separator!

Restore proper crankcase ventilation and engine performance without the high cost of a full oil separator replacement. This Klifex PCV repair kit allows you to replace only the failed internal diaphragm — the most common failure point in 4.0T Twin-Turbo V8 engines.

Over time, the factory membrane breaks down due to extreme heat and boost pressure. This leads to whistling noises, oil consumption, rough idle, and engine faults. Replacing just the diaphragm is a proven and cost-effective solution.

Important Note: Please verify your part number and engine type before purchase to ensure compatibility.
