Features: 1.This ventil sits right after the intercooler, only cold air is in circulation. On many engines the SUV is in front of the intercooler, so there is just hot air in circulation. 2.With this conversion kit, the valve can be moved to a cooler region, thereby this is giving you the advantage that it does not suffer from heat-related damage anymore and also that cooler air is recirculated into the intake system. 3.The cooler the air, the higher the density of the intake air and the higher the density, the better the filling cylinder, whereby a higher efficiency is achieved. 4.The oem valve is installed directly in the turbocharger, and usually over time its getting so damaged through the constant exposure to heat, that it will start to leak. A leaky valve will lead to impaired responsiveness and power losses, which isnt noticed immediately in most cases, since the damage is insidious and does not occur suddenly. As a result, youll get used to a bad nascent response and power loss. 5.Made of quality material, firm and durable for long term use, and conform to strict quality control standards, dependable and reliable.
