Genuine and OEM-quality spare parts for the Weichai WP13 — a 12.5-litre inline-six used in heavy trucks, marine craft and gensets. We source by part number from verified channels in Turkey and deliver with export documents to CIS and worldwide. Reply with an availability check within 2–4 business hours.
The WP13 (12.54 L, inline-6, roughly 460–560 hp) is Weichai's flagship heavy-duty engine — long-haul trucks, marine propulsion and large gensets, in Euro III–VI builds. High output means high wear on injectors, turbochargers and the valvetrain, so genuine-grade parts pay off.
IWH sources WP13 parts by part number — cylinder head, liners, pistons, crankshaft, common-rail injectors, turbocharger and overhaul kits — and ships from Istanbul with clean export documents. Genuine, OEM-equivalent and verified aftermarket, confirmed before you commit.
