PQY Aluminum Oil Catch Can Kit — N54 E82/E90/E92 135i/335i — Overview

The PQY Aluminum Oil Catch Can is a purpose-built solution for the BMW N54 engine found in the 2006–2010 E82 135i and E90/E92 335i. The N54's positive crankcase ventilation system is notorious for routing oily blowby gases back into the intake tract, coating the intercooler, throttle body, and intake valves with a layer of oil residue over time. This catch can intercepts that contamination before it ever reaches your intake system, preserving power and protecting long-term engine health.

At the core of the PQY unit is a dual-baffle, non-clogging separation chamber machined from solid aluminum using a free-flow design — meaning it introduces zero restriction to crankcase breathing. A secondary internal filter element adds another stage of separation, ensuring that only clean air is returned to the system. The result is meaningfully cleaner air entering your combustion chamber compared to a stock setup running no catch can at all.

Installation is straightforward, with the can designed for stealth mounting on the cool side of the N54 motor. Positioning on the cooler side of the engine bay helps prevent any collected oil from re-vaporizing back into the system — a detail that separates a well-engineered catch can from a cheap one. Whether you're running a stock N54 or pushing elevated boost on a tune, this is one of the most cost-effective preventative maintenance upgrades available for these engines.

Note that PQY has updated this kit and the included hoses no longer feature brand logos, but fitment and function remain unchanged. For any E82 or E90/E92 N54 owner serious about keeping their intake tract clean and their engine running reliably for the long haul, the PQY catch can delivers real-world protection in a clean, durable package.
