Weichai WP-series parts at IWH
The WP family is Weichai's core heavy-duty range — the 9.7-litre WP10, 11.6-litre WP12 and 12.5-litre WP13 inline-six engines power trucks, buses, marine craft, gensets and machinery across the CIS and beyond. The same engine appears in many duty cycles, so exact part-number matching matters.
IWH sources WP-series parts by part number — cylinder heads, liners, pistons, crankshafts, common-rail injectors, turbochargers and overhaul kits — consolidates them in Istanbul and ships with clean export documents. Genuine, OEM-equivalent and verified aftermarket, confirmed before you commit.
