S&B Filters produces a cold air intake for the Mk7 GTI that offers several options for how the airbox is configured. For the purposes of the search for the best airbox for the Mk7 GTI the configuration I have chosen to test is with the product acting as a closed intake.
The top lid of the S&B intake can be removed, and there is a removable insert on the bottom side of the airbox that can be removed, both of which might allow for slightly more airflow through the intake, but would also allow engine compartment air in offsetting the purpose of having a “cold” air intake.
The image above is during setup of the flow test on the S&B Filters Cold Air Intake prior to the plastic cover being attached.
The S&B intake kit includes a pipe that joins the air filter to a turbocharger inlet elbow, but the setup does not include an elbow. For this airflow test a Burger Motorsport inlet elbow was chosen to be used in conjunction with the S&B intake as the BMS product has performed well in previous airflow tests that were part of the investigation to find the best turbo inlet pipe for the Mk7.
On the flow bench in a closed configuration the S&B Filters Cold Air Intake flowed 385 CFM @ 28″ of H2O. The S&B intake results are shown on the chart below along with the other Mk7 GTI air intakes that have been flow tested so far.
