Name: Cobb 05-09 Subaru Legacy GT/Outback XT SF Intake SF Airbox (cobb724300-BL)
SKU: 127438

The advantages of both a short ram intake and a cold air intake are incorporated in this intake, which also has an integrated airbox, with none of the drawbacks. This system makes use of a number of distinctive features in an effort to maintain a performance-optimal flow while reducing turbulence that may result in engine management issues. We create a unique air flow straightener grid using a CFD-designed velocity stack starting from a special conical cloth air-filter element. For accurate readings, the mass air flow sensor needs the incoming airflow to be smoothed out as it passes over this straightener grid. This gets rid of the "dead spots" caused by turbulence in other aftermarket intakes. These essential design components are not utilized by any other aftermarket Subaru intake system. In order to provide a system that looks as good on the outside as the technical advancements happening on the inside, we utilize a one-piece design constructed from a high-temperature plastic composite. Not only does this save weight compared to the previous metal design, but the plastic composite material also offers much better heat rejection properties that help keep intake air temperatures cooler. In contrast, intake systems constructed using metal castings or piping can actually retain underhood heat and in turn heat the incoming air. The SF Air Box adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The factory inlet directs cold air from the front grill to the SF Air, which encloses the SF intake. Hot engine bay air that robs horsepower is prevented from entering the intake system. This unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague in-fender cold air intakes

NOTES

As with all aftermarket intakes for MAF-based Subaru appropriate tuning is required for safe engine performance. COBB Tuning offers Accessport Off-The-Shelf (OTS) maps optimized for the SF Intake for the 05-06 Legacy GT. Any 2007-2009 model year Legacy GT will require custom tuning to run properly with the SF intake installed.
