LESS RESTRICTIVE THAN STOCK

We swapped the location of the intake box and battery, allowing our intake to not only be closer to but also directly in line with the front air inlet. Additionally, our intake tube has minimal bends as it connects to the turbo inlet. These details result in a signifcant decrease in restriction compared to stock intake.

LARGE CLEAR LID

Our signature large clear lid provides great looks. Featuring a rubber lid seal to keep out power robbing engine heat.
