Zero Sports Inner Duct Supporter For WRX STI VAB

Car Make: Subaru
Model: WRX-STI VAB

Due to the increase in the running wind flowing from the bonnet duct (front hood duct) and the vibration caused by the gap on the road surface, the resin inner duct flutters, causing turbulence and the intercooler does not hit the wind cleanly. As a result, the intake air temperature of the intercooler becomes high and the air density becomes low, which leads to power down and deterioration of fuel efficiency. By suppressing the fluttering of the inner duct with this product, the running wind to the intercooler is rectified and efficiently guided, which promotes a decrease in the intake air temperature and demonstrates the original engine performance.

● Lightweight aluminum is used
● Slit processing suppresses the load of overhang
● High-quality alumite treatment
● Brings out the performance of the genuine intercooler
