VW MK4 Jetta 1.8T Intercooler Upgrades
Drop intake temperatures, boost HP & Torque with an intercooler for your Mk4.
The formula is simple. However, it's easier said than done.
Leave it to ECS to accept the challenge by providing brilliant designs from APR, Euro Sport, Forge, CTS, and Neuspeed.
Significant HP gains have been reported due to the substantial drop in intake temperatures.
Additionally, a cooler running engine better resists heat expansion and stress, increasing the longevity of your powerplant.
