PQY Aluminum Oil Catch Can Hose Kit for BMW N54 335i (2006–2010) — Double‑Baffle, Removable Reservoir

PQY’s aluminum oil catch can hose kit traps crankcase oil and vapor before they reach the intake, protecting your BMW N54 335i’s intake tract and promoting cleaner engine breathing.

This compact, lightweight kit is designed specifically for BMW N54 engines in 335i, 135i and related E90/E92/E82 models from 2006–2010. Constructed from machined aluminum with an internal filter and a double-baffle, it separates oil from blow-by gases and stores recovered oil in a removable reservoir. The kit includes pre-cut hoses and mounting hardware for a discreet installation on the cool side of the motor.

How does this catch can reduce oil buildup in the intake?

The internal filter and dual-baffle layout trap oil droplets and prevent them from re-entering the intake tract where they can coat throttle bodies, intercoolers, and intake valves. Cleaner intake components maintain airflow and reduce deposit-related issues over time.

• Double-baffle non-clogging separation design captures fine oil mist.
• Internal mesh filter improves oil/air separation efficiency.
• Removable reservoir makes oil removal fast and mess-free.

Will this kit fit my BMW N54 335i from 2006–2010?

Yes — PQY engineered this kit for N54-powered 335i, 135i and related E90/E92/E82 models in that year range. It uses application-specific hose lengths and mounts to fit the factory layout without major modification.

• Compatibility: BMW N54 335i, 135i; E90, E92, E82 (2006–2010).
• Includes hoses sized for factory routing to the cool side of the motor.
• Ships with mounting bracket and hardware for stealth placement.

How is this unit built and maintained?

The body is forged from aluminum for corrosion resistance and light weight. Inside, a free-flow design reduces restriction while the double baffle and filter separate oil efficiently. Maintenance is simple: undo the drain or remove the reservoir to empty trapped oil.

• High-quality aluminum body for long-term durability.
• Free-flow design minimizes intake restriction during operation.
• Serviceable reservoir and filter for easy cleaning and disposal.

What performance or longevity benefits should I expect?

By intercepting oil and varnish precursors, the catch can helps keep intake and turbo-related components cleaner, which can improve consistency of airflow and reduce maintenance frequency. It’s focused on preserving engine components rather than increasing power.

• Reduces oil and carbon buildup on intake and intercooler surfaces.
• Helps retain throttle and turbocharger responsiveness over time.
• Minimal impact on intake flow thanks to the free-flow internal design.

Who is this for? This PQY aluminum oil catch can hose kit is for BMW owners with N54 engines who want a durable, serviceable way to limit oil contamination of intake components. It’s suited to daily drivers, tuners, and track enthusiasts who prefer preventative maintenance and a stealthy, OEM-friendly install.
