FAQs

Q1: How do I verify if this HX35 turbocharger fits my Iveco tractor? 

Please check the nameplate on your current turbocharger's compressor housing for the part number 4036158 or the Iveco OEM number 504216822. Since the NEF engine is used across multiple tractor brands (Case, New Holland, Iveco), matching the specific 7-digit Holset or 9-digit Iveco number is the most reliable way to ensure a correct fit.

Q2: Does this turbocharger provide the same durability as the original Holset unit? 

Yes. Our turbochargers are precision-calibrated to match the exact airflow requirements of the NEF 6-cylinder engine. By using high-grade K18 nickel-alloy turbine wheels and professional VSR balancing, we ensure that power output and thermal stability match original factory standards for high-uptime agricultural work.

Q3: Are any modifications needed for installation on a 6.7L NEF engine? 

No modifications are required. This is a 100% "drop-in" direct replacement. All mounting flanges, oil inlet/outlet ports, and air intake connections are identical to the original factory specifications for a seamless and quick installation, minimizing downtime in the field.

Q4: What type of warranty do you provide for heavy-duty agricultural use? 

We understand that agricultural tractors often operate in high-dust and high-vibration environments, which is why we stand behind our quality with full technical support for equipment owners and maintenance workshops worldwide.

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.
