The part matters — but so does the factory behind it. Here's exactly who manufactures this component.
FactoryPlug is a supply-chain intelligence directory, not a store. We hold no inventory and process no checkouts — this record exists so you can see the real terms before you contact the supplier yourself.
Also listed and searched as: N55 turbo upgrade, PWG turbo, hybrid turbo, stage 2 turbo, N55 upgraded turbocharger and pneumatic wastegate turbocharger.
PWG fitment: 18539700001/11657583908 are N55 2011-2013 PWG-era OE numbers; all 6 gallery photos show the pneumatic wastegate canister + linkage rod (no electronic actuator) — visual PWG confirmation by eye 2026-10-02. NOT interchangeable with EWG (2014+) N55 turbos — PWG vs EWG is the #1 buyer mix-up; buyer confirms year/trim/VIN with seller before paying. Checked against our known wrong-fitment list — not flagged. US comparator: Pure Turbos N55 Stage 2 PWG (PURE-N55-0001KT), $2,800.00 at ECS Tuning (Listing details checked live on 2026-10-02; includes $300 refundable core charge). Price math $2,800/$890 = 3.1x, price comparison only. Rejected runners-up this run: Beijing Debao Zhongda PWG-title listing (gallery hero shows EWG electronic actuator — photo-match fail), Xi'an Hengye E92 N55 listing (center "HENG YE" watermark over the product — dead per logo rule; "PWG EWG" title ambiguity). Carousel set n55-pwg-turbo staged (5 slides, QC gate pass, caption at ~/workspace/your_files/kit-carousels/n55-pwg-turbo-caption.txt); publishing needs Conroy's per-post approval. Demand: tonight's "e90 n55 turbo?" IG comment (E90 N55 = 2011-2013 = PWG).
