Intake Port Interface WG9725190902 for SINOTRUK HOWO Trucks OEM Air Intake Connection Component

High-Temperature Reinforced Nylon Flange | Sealed Turbo-to-Intercooler or Manifold Coupling | Direct Replacement for Emission-Compliant Engines

Ensure optimal engine breathing and emission system integrity with the genuine-spec Intake Port Interface (Part No. WG9725190902)—a critical OEM air pathway component engineered for SINOTRUK HOWO A7, T7H, TX, and TH7 heavy-duty trucks equipped with Weichai WP10H, WP12, or MAN TC06/TC08-derived engines.

This precision-molded interface serves as a sealed flanged connector between key intake system elements—commonly linking the turbocharger outlet to the intercooler inlet, or the intercooler outlet to the intake manifold. Designed to maintain leak-free, high-flow air delivery under extreme thermal cycling and boost pressure, it plays a vital role in preserving engine efficiency, torque response, and SCR/DPF compliance.

Constructed from 30% glass-fiber-reinforced nylon (PA6-GF30) with integrated EPDM sealing lips or O-ring grooves, this component withstands continuous exposure to hot compressed air (up to 150°C) and boost pressures up to 300 kPa (43 psi)—typical in modern Euro IV/V/VI-compliant diesel platforms.

Its geometry includes precise bolt hole patterns, alignment tabs, and smooth internal contours to minimize flow turbulence, ensuring consistent air mass readings for the MAF sensor and stable combustion control.
