4" Bar and Plate Intercooler

The On3 Performance 4" Intercooler is engineered for high-performance applications, offering significant cooling efficiency for turbocharged and supercharged vehicles. This intercooler utilizes a robust bar and plate design, known for its durability and effectiveness in dissipating heat. The cast aluminum end tanks enhance the unit's strength and ensure long-term reliability under demanding conditions. With a 3" inlet and 3" outlet, this intercooler is designed to integrate into many performance setups. The core measures 12" tall by 23.5" wide, with an overall width of approximately 31" from inlet to outlet. Its 4.0" thickness contributes to its substantial cooling capacity. On3 Performance recommends this intercooler for applications reaching up to 1000whp. It is particularly well-suited for vehicles producing 500hp or more, provided there is sufficient physical space to accommodate the 4" core. The company has conducted extensive testing on dynos and at the track to optimize the performance and efficiency of their intercoolers, aiming for minimal boost pressure drop across the core while maximizing cooling. Cooler intake air translates directly to increased power output, making this intercooler a valuable upgrade for performance enthusiasts.
