Product Details

The ECS Tuning MQB Cast Aluminum Intercooler Upgrade boosts power and lowers intercooler outlet temps by maximizing core volume and more efficiently dispelling heat over the OEM sandwich-mounted intercooler. Designed and engineered by our in-house R&D Team to replace the under-performing stock intercooler, our intercooler is more efficient at cooling the turbocharged air with less pressure drop than stock. The factory tube and fin intercooler is not up to the task of shedding heat efficiently at higher power levels. If you plan to go above stock boost levels an intercooler upgrade is a must. With our ECS Tuning OE-Location Intercooler Upgrade we recorded lower intercooler outlet temperatures, lower pressure drop and an increase in cooling system efficiency. 

Our design features high quality cast aluminum end tanks with integral flow dividers on the intercooler inlet for even flow distribution across our massive 24.5” x 16.5” x 2.0” {808.5 in³} aluminum bar and plate core, which lends to an increase in volume of +39% over the OEM GTI intercooler, for maximum heat dissipation. Our intercooler was in-house engineered to provide a bolt-on cooling solution for the VW and Audi MQB Gen3 platform. Through our in-house evaluation on our ECS Shop MK7 GTI, we measured a maximum increase of +20 WHP @ 5,750 RPM and +18 WTQ @ 5,750 RPM along with an increase of +22% in cooling efficiency at redline and -90° F. lower intercooler outlet temperatures. 



  • 3D CAD designed to allow the best placement and larger volume core over stock all while requiring no modifications to your vehicle 

  • Retains all OEM cooling air guides and mounting features. Compatible with forward collision warning radar, if equipped.

  • Aluminum Straight Vane Bar and Plate Core: 24.5” x 16.5” x 2.0” (808.5 in³ internal core volume) 

  • Raw Cast Aluminum End Tanks with smooth-flowing internal inlet and outlet flow-paths 

    • Cast 60mm barbed connections keep hoses secured and minimizes the risk of hoses blowing off and allows compatibility with OEM and ECS intercooler hoses

    • Internal flow dividers on the intercooler inlet ensures an even flow distribution between the entire surface of the intercooler core 

    • End tanks are TIG welded to the intercooler core and the complete assembly is pressure tested to 3.5 BAR at 0% leak down to ensure sealing capacity

    • Cast mounting features are precision machined to ensure quality fitment 



  • ECS MQB Cast Aluminum Intercooler 

  • A/C Condenser Locking Plates with Hardware 



Dyno tested on our In-House Mustang Dyno on our shop 2015 MK7 GTI 2.0T 6 speed manual, comparing the OEM GTI intercooler to our ECS Tuning MQB OE-Fitment Upgrade. Please see our documented results under the INSTALLATION Tab for more information.
