E-Line 30-Row Stacked Plate Oil Cooler | 13″ x 9.25″ x 2″ OGEN.STP.101 | No Fan The Tallest E-Line. Maximum Stacked Plate Cooling Surface Without the Fan. The 30-row is the largest no-fan option in the E-Line stacked plate family, and for applications where cooling demand is high but a fan isn’t necessary — or where an existing fan is already handling airflow — it’s the right call. More rows mean more heat exchanger surface, more fluid contact time per pass, and lower steady-state temperatures under sustained load. With a BTU rating of 38,000–54,000, the 30-row steps meaningfully above the 25-row and is the right choice for applications that run fluid temperatures consistently high under sustained load. Same premium E-Line stacked plate construction throughout, built to the same standard as other premium coolers on the market. Engineered to withstand pressures up to 250 psi. The right fit for transmission, rear end, and power steering applications that need serious heat rejection capacity without the added complexity of a fan. Specs: 13″ × 9.25″ × 2″ | 30-row | BTU Rating: 38,000–54,000 | -10 AN ORB ports | No fan | Best suited for transmission, rear end, power steering
