If you want a heavy-duty, direct-fit replacement for your Ram 2500 or 3500 with a 6.4L V8 engine, choose PM PERFORMOTOR DPI-13895; if you need a robust aluminum core radiator specifically engineered for the Acura MDX or ZDX from the late 2000s, choose PHILTOP CU2938.
These two parts serve completely different owners and distinct vehicle platforms. You cannot swap them between a massive American truck and a Japanese luxury SUV. The decision isn't about which brand is "better" in a vacuum; it is entirely about whether your vehicle matches the specific fitment requirements of one over the other. I have analyzed the specifications, construction materials, and design intent of both units to help you cut through the noise and find the exact match your engine needs to survive another season on the road.
• PM PERFORMOTOR DPI-13895: Built with aircraft-grade T-6061 aluminum and a massive 33-inch width, this unit is designed for high-heat dissipation in heavy-duty work trucks. It trades off having integrated oil coolers for a pure, focused cooling solution that fits perfectly into tight engine bays without modification.
• PHILTOP CU2938: Features a transmission oil cooler (TOC) included as standard, making it a more comprehensive replacement for Acura's complex cooling system, while utilizing a durable aluminum core and plastic tanks to meet IATF 16949 quality standards.
• Who each pick is for: Choose the PM PERFORMOTOR unit if you own a 2019–2024 Ram 2500/3500 and need a rugged, no-nonsense upgrade for your gas V8. Choose the PHILTOP unit if you drive a 2007–2013 Acura MDZ or ZDX and require a factory-spec replacement that handles both engine and transmission heat.
This radiator is built for the owner who pushes their vehicle hard. If you drive a Ram 2500 or 3500 equipped with the 6.4L V8 gas engine, you are dealing with significant thermal loads, especially when hauling cargo or towing. The DPI-13895 addresses this directly by offering a one-row cooling design that prioritizes rapid heat dissipation. The core dimensions are substantial, measuring 33-7/16 inches wide by 20-5/16 inches high, providing ample surface area to keep engine temperatures in check under pressure.
The construction here screams durability. Unlike standard stamped metal units, this radiator utilizes an aircraft-grade T-6061 full aluminum core. This material choice is critical for truck owners who face extreme temperature fluctuations and constant vibration on rough roads. The wear-resistant PVC materials used for the tanks further reinforce its ability to withstand daily wear and tear, ensuring the cooling system remains reliable mile after mile. It is an OEM-spec direct fit, meaning it bolts right into place where the original part sat, requiring no drilling or custom fabrication.

However, there is a trade-off to consider regarding auxiliary cooling features. This specific model does not include an Engine Oil Cooler (EOC) or a Transmission Oil Cooler (TOC). For many truck applications, the primary focus is simply moving coolant through the core efficiently. If your existing setup relies on separate lines for oil cooling, this radiator serves that function perfectly well. But if your vehicle design integrates those coolers directly into the radiator tank, this part might not be the right path unless you plan to retrofit those components separately. It is strictly for those who need a powerful, standalone cooling solution for their heavy-duty daily driver.
Owners of the Acura MDX (2007–2013) and the Pontiac ZDX (2010–2013) know that these vehicles require precise engineering to maintain performance. The PHILTOP CU2938 is designed specifically for this ecosystem, fitting models like the MDX and ZDX with exacting precision. Its core measures 30.25 inches in width and 19.69 inches in height, offering a compact yet efficient footprint that fits within the constraints of the mid-size luxury SUV platform. The inclusion of a Transmission Oil Cooler (TOC) is a major differentiator here; unlike the Performotor unit, this radiator integrates the necessary cooling for the transmission fluid directly into the assembly.
Quality assurance is a central pillar of this product's design. This is an automotive industry standard that validates the manufacturing process for reliability and consistency. For an owner looking to replace a failing radiator on a decade-old luxury vehicle, knowing that the new part meets these stringent international quality benchmarks provides peace of mind. The combination of an aluminum core and plastic tanks balances weight reduction with structural integrity, preventing leaks while maintaining effective heat transfer.
The installation process is streamlined for the DIY mechanic or the shop technician. Manufactured to align with original factory specifications, the unit promises a quick replacement with minimal maintenance time. There is no need to hunt for adapters or modify mounting points. However, potential buyers must verify their specific VIN and model year carefully, as the fitment is exclusive to the 2007–2013 MDX and 2010–2013 ZDX. It is not a universal part. If you drive any other make or model, this component will not fit. It is a specialized tool for a specific job, offering a complete cooling solution that includes the transmission cooler function essential for these particular drivetrains.
• Best for Heavy-Duty Trucks → PM PERFORMOTOR DPI-13895 is the clear choice for Ram 2500 and 3500 owners needing maximum cooling capacity for the 6.4L V8.
• Best for Luxury SUVs → PHILTOP CU2938 is the only option for 2007–2013 Acura MDX and 2010–2013 ZDX owners requiring a direct OE replacement.
• Integrated Cooling Features → PHILTOP wins for those needing a built-in Transmission Oil Cooler (TOC); the Performotor unit excludes this feature entirely.
• Material Construction → PM PERFORMOTOR highlights aircraft-grade T-6061 aluminum, emphasizing extreme durability for rugged use cases.
• Certification Standards → PHILTOP cites IATF 16949 certification, signaling adherence to global automotive manufacturing quality protocols.
• Core Dimensions → The Performotor offers a wider core (approx. 33.5 inches) compared to the PHILTOP (approx. 30.25 inches), reflecting the larger cooling demands of the Ram truck.
• Installation Complexity → Both claim direct bolt-on OE fitment, but the Performotor explicitly notes professional installation is recommended due to the lack of instructions, whereas PHILTOP emphasizes reduced maintenance time.
• Target Audience → PM PERFORMOTOR targets truck owners who prioritize raw cooling power and ruggedness; PHILTOP targets SUV owners who value factory integration and certified quality.
If I were standing in my garage with a 2022 Ram 2500 that was overheating, I would grab the PM PERFORMOTOR DPI-13895 immediately. The sheer size of the core and the use of aircraft-grade aluminum give me confidence that it can handle the thermal stress of a heavy-duty gas engine better than a generic replacement. It feels like a piece of equipment built to last, matching the toughness of the truck itself. Conversely, if I owned a 2010 Acura MDX, I would buy the PHILTOP CU2938 because of the integrated transmission cooler. That single feature makes it the only logical choice for keeping the entire powertrain cool without needing to add external plumbing. For truck owners specifically, the Performotor unit is the superior engineering solution for the application it serves.
No, the DPI-13895 data sheet explicitly states that neither an Engine Oil Cooler nor a Transmission Oil Cooler is included. It is designed solely for engine coolant circulation.
No, this unit is strictly for the 2007–2013 MDX and the 2010–2013 ZDX. It will not fit earlier or later generations of the MDX.
Both units share a similar core thickness of approximately 1 inch, though the overall width and height differ significantly based on the vehicle they serve.
Yes, both products are described as direct OE fitment replacements designed to install without drilling or modification, provided your vehicle matches the listed fitment years and models.
