GrimmSpeed now offers a great solution to upgrading your intercooler without doing major modifications. GrimmSpeed Top Mount Intercooler Upgrade Kits allow you to install a much larger and better flowing intercooler where the stock one mounts. This makes it a simple and effective upgrade for when you want to turn up the boost without rerouting intercooler piping.

Made from lightweight aluminum and built to the highest standard, each end tank is carefully constructed to meet the needs of the hot air going in and the cooler air moving out. Each unit is welded on to a bar and plate core for exceptional heat dissipation and tested for proper flow and no leaks. Some kits will also include a splitter for the hood scoop to increase air throughout the intercooler. Providing a much simpler solution than a front mounted kit makes this essential for the weekend warrior!

Key Features:

• Simple bolt on design.
• Bolts on to the same place as the stock intercooler.
• Lightweight air-to-air intercooler design.
• Can improve temps from 30F-40F!
• Most kits include a scoop splitter for improved airflow across the intercooler.
