If you want a cooling solution engineered for the specific thermal demands of the Infiniti Q50 and Q60 with an integrated transmission cooler, choose JC Whitney Engine Coolant Radiator; if you need a direct replacement unit sized for the Acura MDX or ZDX that prioritizes a robust aluminum core and certified manufacturing standards, choose PHILTOP CU2938. This isn't about guessing which part fits better; it is about matching the exact physical dimensions and cooling requirements of your vehicle platform to the component's design. Whether you are maintaining a performance sedan like the Infiniti or a rugged SUV like the Acura, getting the radiator wrong leads to overheating, and getting it right means reliable operation on the road.
• JC Whitney Engine Coolant Radiator: Its biggest strength is the precise fitment for Infiniti models (Q50/Q60) combined with an included transmission oil cooler, but its trade-off is a narrower core thickness of 1.06 inches compared to some competitors. This pick is for owners of 2016–2022 Infiniti vehicles who need a complete assembly ready for installation.
• PHILTOP CU2938: Its biggest strength is its substantial build with a 1-inch thick core and IATF 16949 certification, offering peace of mind regarding manufacturing quality, though it lacks an engine oil cooler. This pick is ideal for 2007–2013 Acura MDX and ZDX owners seeking a durable, spec-compliant replacement.
• The Bottom Line: One serves the high-performance luxury coupe/sedan lineage, while the other serves the mid-size luxury SUV lineage; they are not interchangeable.
The JC Whitney Engine Coolant Radiator Assembly is built specifically for the 3.0L engines found in the Infiniti Q50 and Q60 from model years 2016 through 2022. If you drive one of these vehicles, this part addresses the unique spatial constraints and cooling loads of that chassis. The design features a down-flow type configuration with a core height of 14.94 inches and a width of 28.38 inches, fitting snugly within the engine bay of these specific Infiniti models.
What makes this unit stand out is the inclusion of a transmission oil cooler directly integrated into the assembly. In modern vehicles where space is tight and heat management is critical, having both engine and transmission cooling handled by a single, unified unit simplifies the plumbing and reduces potential leak points. The construction utilizes reinforced seams and secure crimping designed to withstand vibration and thermal shock, which are common issues in stop-and-go city driving or spirited highway cruising. The use of an aluminum core paired with plastic tanks balances weight and corrosion resistance, ensuring the unit can handle the rapid heat dissipation required for the 3.0L powertrain without adding unnecessary bulk.
This product is best suited for drivers who value a "plug-and-play" experience. Because it comes as a complete assembly with the correct reference part numbers (JFBAJCWRAD00291, 13630, 214604HK0A), it eliminates the guesswork often associated with rebuilding older radiators. However, if you own a different make or model, or if you are looking for a radiator without a transmission cooler, this specific unit will not work for you. It is a targeted solution for a specific niche of Infiniti enthusiasts and daily drivers who need their cooling system restored to factory-like reliability.

The PHILTOP CU2938 is engineered exclusively for the Acura MDX and ZDX platforms spanning the 2007 to 2013 model years. If you own one of these SUVs, this radiator is designed to match the original factory specifications exactly, ensuring that the mounting points align perfectly with the frame. The core dimensions here are significantly larger than the Infiniti unit, measuring 19.69 inches in height and 30.25 inches in width, providing a large surface area necessary for cooling the heavier V6 engines typically found in these SUVs.
A key feature of the PHILTOP unit is its adherence to the IATF 16949 certification standard. While many parts simply claim to be durable, this certification indicates that the manufacturing process follows strict automotive quality management systems. The radiator undergoes rigorous performance testing to ensure it remains stable and leak-free under pressure. Like the JC Whitney option, it features an aluminum core and plastic tanks, but it includes a transmission oil cooler while explicitly noting the absence of an engine oil cooler in its specification list. The core thickness is listed at 1 inch, providing a solid foundation for heat exchange.
This product is the right choice for Acura owners who want a direct OEM-style replacement without the hassle of sourcing individual components. The easy-to-install design ensures that maintenance time is reduced, which is a significant benefit for anyone working in a home garage. However, because it is sized specifically for the 2007–2013 MDX and ZDX, it has no application for newer models or other brands. It is a dedicated upgrade for those looking to extend the life of their Acura's cooling system with a component that meets established industry quality benchmarks.
• Best for Infiniti Q50/Q60 Owners → JC Whitney Engine Coolant Radiator, as it is the only option listed with compatibility for the 2016–2022 Infiniti 3.0L models.
• Best for Acura MDX/ZDX Owners → PHILTOP CU2938, which is specifically dimensioned and coded for the 2007–2013 Acura SUV lineup.
• Best for Integrated Cooling Systems → JC Whitney Engine Coolant Radiator, because it combines the engine coolant radiator with a transmission oil cooler in a single compact assembly for the Infiniti platform.
• Best for Certified Manufacturing Standards → PHILTOP CU2938, given its explicit mention of IATF 16949 certification and rigorous performance testing protocols.
• Best for Larger Core Surface Area → PHILTOP CU2938, with a core height of 19.69 inches versus the JC Whitney's 14.94 inches, suiting the larger SUV footprint.
• Best for Precise Fitment Reference → Both offer strong reference codes, but JC Whitney lists specific OEM equivalents like 214604HK0A for Infiniti, while PHILTOP lists codes like 19010RYEA52 for Acura.
• Best for Thermal Shock Resistance → JC Whitney Engine Coolant Radiator highlights reinforced construction and secure crimped seams specifically for resisting thermal shock in the Infiniti chassis.
• Best for Quick Installation → PHILTOP CU2938 emphasizes being manufactured to original factory specifications to reduce maintenance time for Acura owners.
In my opinion, the decision between these two units comes down entirely to your vehicle, not the brand prestige. I would buy the JC Whitney Engine Coolant Radiator if I were restoring or maintaining an Infiniti Q50 or Q60, because the integration of the transmission cooler and the specific down-flow design tailored to that 3.0L engine make it the logical choice for keeping that specific car cool. Conversely, I would choose the PHILTOP CU2938 for an Acura MDX or ZDX, as the IATF certification and the larger core dimensions are exactly what that SUV needs. Neither is universally "better"; they are specialized tools for specific electric and combustion engine platforms. For electric vehicles, the principle remains the same: match the spec sheet to the machine. If you have an electric vehicle requiring a similar cooling architecture, you would look for a unit that matches those specific electrical thermal loads, just as you match the radiator to the engine block.
No. The JC Whitney unit is strictly for Infiniti Q50 (2016–2022) and Q60 (2017–2022), while the PHILTOP unit is for Acura MDX (2007–2013) and ZDX (2010–2013). They do not cross-fit between these manufacturers or year ranges.
Yes, both the JC Whitney Engine Coolant Radiator and the PHILTOP CU2938 list a transmission oil cooler as an included feature, making them suitable for vehicles where transmission cooling is integrated into the main radiator assembly.
The PHILTOP CU2938 has a larger core, standing 19.69 inches tall and 30.25 inches wide, whereas the JC Whitney unit is smaller at 14.94 inches tall and 28.38 inches wide, reflecting the different engine bay layouts of the respective vehicles.
Both units utilize an aluminum core and plastic tank material, which is standard for modern radiators to balance durability with weight reduction and corrosion resistance.
