The Step-Up Choice in the E-Line Family. When the 19-row isn’t enough but you don’t need to jump all the way to the 30-row, the 25-row hits the middle ground with a taller core and a single high performance fan included. Same premium E-Line stacked plate construction built to the same standard as other premium coolers on the market, same suitability for transmission, rear end, and power steering applications — just more cooling surface and forced airflow built in from the start. The additional rows mean more fluid passes through more heat exchanger surface per cycle, which translates directly to lower steady-state temperatures under sustained load. The BTU rating of 33,000–46,000 reflects that step up in capacity over the 19-row. The included high performance fan moves 500 cfm, ensuring performance holds up regardless of vehicle speed or cooler mounting location. Engineered to withstand pressures up to 250 psi. At 13″ × 7.7″ × 2″ the 25-row is taller than the 19-row but carries the same footprint in every other dimension, making it a straightforward upgrade in most mounting situations. -10 AN ORB fittings.
