S300A113 replacement turbocharger for E7, EM7 and AI427 12.0L diesel engines. Replaces 173526, 631GC5172M3, 631GC5172AM3X and other listed turbocharger references. Suitable for MR, LE, CV713 and selected IEGR trucks from 2002–2007. Designed for reliable boost response, heavy-load pulling power and commercial fleet operation.

Product Overview

High-Performance S300A113 Turbocharger for E7, EM7 & AI427 Trucks

  • Designed for E7 12.0L Engines: This S300A113 turbocharger is developed for E7 and related EM7 12.0L diesel engine applications. It helps restore the boost pressure required for stable engine performance, strong acceleration and dependable pulling power.
  • Built for Commercial Truck Operation: MR, LE and CV713 trucks are used for regional transport, construction, refuse collection and vocational service. This turbocharger is designed to provide consistent airflow during loaded driving, repeated acceleration and long working shifts.
  • Strong Response Under Load: The S300A113 turbocharger is matched to the airflow requirements of the E7-350/400 engine platform. It supports smooth boost build-up at working speeds, helping the truck maintain torque when climbing grades, towing trailers or operating at full load.
  • Suitable for IEGR Engine Applications: This turbocharger is intended for selected IEGR truck configurations. Correct boost delivery is important for maintaining the engine’s air-fuel balance and supporting stable operation under the E7 emission-control system.
  • Direct Replacement Configuration: The unit is manufactured for the listed applications, with the main mounting points, oil connections and air passages designed to match the original S300A113 arrangement. Compare the original turbocharger, actuator position and housing orientation before ordering.
  • Practical Choice for Fleet Maintenance: This turbocharger is suitable for repair shops, fleet maintenance departments and engine refurbishment projects. It can be used to replace a worn unit showing low boost, excessive smoke, slow acceleration, oil leakage or abnormal turbocharger noise.

Frequently Asked Questions (FAQs)

Q1: Does this S300A113 turbocharger fit the E7 12.0L engine?
Yes, it is designed for selected E7 and EM7 12.0L applications using references such as 173526, 631GC5172M3 or 631GC5172AM4. Check the original turbocharger identification plate and engine configuration before ordering.

Q2: What is the difference between 631GC5172M3, M4, M5 and M6?
These numbers represent different service, production or application references for related S300A113 turbochargers. They may correspond to different production revisions or truck configurations. Confirm the complete turbocharger, including the housing, mounting position and air connections, rather than matching only the base model.

Q3: Can this turbocharger be used on both MR and LE trucks?
It may fit selected MR and LE trucks equipped with the same E7/EM7 engine and matching turbocharger reference. The chassis model alone is not sufficient to confirm compatibility, so compare the original part number and turbocharger configuration before purchase.

Q4: What should be checked before installing the replacement turbocharger?
Replace the engine oil and filter, inspect the oil feed and drain lines, clean the intake system and check the charge-air cooler for oil or debris. Prime the turbocharger with clean engine oil before starting the engine, then inspect the intake, exhaust and oil connections for leaks.

Q5: Do you provide worldwide shipping?What is the delivery timeframe?

We ship globally via premium carriers like DHL,FedEx,and UPS,as well as sea freight for bulk orders.In-stock items are typically dispatched within 24-48 hours. Express delivery to North America and Europe usually takes 5-7 business days.
