Walnut Blasting Nozzle Set for BMW B47 N47 N57 B57 M57 Engines | 2-Pack | ABS 3D Printed | Vacuum-Port Design

Blast Clean. Extract Instantly. Zero Mess.
Carbon build-up on intake valves chokes your BMW diesel — rough idle, sluggish response, poor fuel economy. Walnut blasting is the proven fix, but loose media scattered across your engine bay is a nightmare to clean. This 2-nozzle set changes that entirely. Each nozzle seals against the cylinder head intake port while a vacuum hose connects to the side adapter. Blast media goes in through the small port, dislodges carbon, and gets sucked straight out — no debris flying around, no post-job scrubbing. A clean engine bay and clean valves in one operation.

Key Features & Your Benefits:

• Precision Fit for BMW Diesel Engines: Specifically contoured to seal against the intake ports on:

  • B47, N47, N57, B57, M57 engines
    (Please visually compare the nozzle shape with your cylinder head port layout before ordering.)

• Dual-Port Design — Blast and Vacuum Simultaneously: The central small port accepts a walnut blasting gun nozzle. The side adapter connects directly to a standard vacuum cleaner hose. Media enters, breaks up carbon, and is immediately extracted — all contained within the tool.

• No Flying Media, No Cleanup Chaos: Unlike open-port blasting where walnut shells ricochet across the engine bay, this closed system keeps everything contained. Your alternator, belts, sensors, and wiring stay clean and debris-free.

• 3D Printed in Durable ABS: Made from tough, heat-resistant ABS that holds its shape under use and cleans up easily after the job. Not brittle PLA. Built for real workshop conditions.

• Sold as a Pair — Two Nozzles, Complete Job: Two nozzles allow you to work on two cylinders simultaneously or keep a spare on hand. Ideal for professional workshops and serious DIYers tackling carbon cleaning.
