Keep your performance engine running cleanly and efficiently with the Burgaflex Crankcase Ventilation Connecting Pipe for Cylinders 1-4. In high-output Bavarian engines, maintaining precise crankcase pressure and effective oil-gas separation is essential to protecting engine health and sustaining peak power output. Factory plastic breather pipes are notoriously prone to hardening, cracking, and suffering internal wall degradation due to constant exposure to high underhood temperatures and vaporized engine oil. A cracked connecting pipe leads to boost-robbing vacuum leaks, poor throttle response, and oil contamination inside the intake tract. This OEM-quality Burgaflex connecting pipe is built specifically to address those failure points, ensuring a factory-tight seal and reliable blow-by gas routing for cylinders 1-4. Perfect for routine maintenance, PCV refreshes, or overhaul projects, this component restores the factory-engineered crankcase seal so your engine runs smoothly and operates at peak efficiency.
