Direnza Ford Focus MK4 ST – MVT Front Mount Intercooler 2018 – Present

Direnza

                          Provided performance gains of +21.8bhp / 16.8nmIntake Temperatures by 10°C116.7°c Temperature dropDesigned using state of the art 3D CAD and CFD modellingDirect replacement for the original IntercoolerTIG welded for maximum strength and durabilityMVT technology designed by Direnza offers greater intercooler efficiency in comparison to other aftermarket alternatives. This is achieved through the use of carefully placed vanes in the end tank which evenly distribute air across the entire core. Ensuring the full surface area of the intercooler core is optimised to cool your charged air, resulting in more power.Test car: Ford Focus MK4 ST 291.4hp / 429.2nmPut through its paces on a state-of-the-art Maha MSR 500 Dyno, our Multi Vane Technology Intercooler for the Focus ST yielded some highly impressive results.After installing our revolutionary MVT Intercooler, engine performance improved significantly. With the Focus now producing 313.2hp & 445.9nm of torque, that’s an increase of +21.8hp & 16.7nm of torque without any additional tuning.What’s more impressive is the cooling power of MVT. Using sophisticated data logging software, we measured intercooler inlet temperatures at 140.1°c. The stock intercooler performed well, reducing this to 63.9°c at the Intercooler outlet. However, with MVT installed, outlet temps were reduced an additional 40.5°c down to 23.4°c! That’s an overall temperature drop of 116.7°c. Thus, providing huge tuning potential and greater reliability when combined with a remap & supporting modifications. The perfect addition to any track or modified road car!  Click here for the fitting guide
