Features & Product Details

RallySport Direct proudly carries COBB Tuning products to provide the die-hard car enthusiast with a quality product that is a result of decades of engineering, expertise, and careful manufacturing methods that you can always be satisfied with. 

On this page, you are looking at the COBB Tuning Big SF Intake System. The intended purpose of this component is to be a direct replacement of your restrictive factory intake system. This is accomplished with a 3" aluminum pipe that features smooth bends and a smooth interior lining that will limit turbulence and back-pressure under acceleration. Air is filtered through a reusable green filter which can be cleaned and serviced throughout the life of the vehicle. 

The filter will be protected by an aluminum filter box that will shield away harmful heat away from the filter. Both the intake piping, as well as the heat shield will come powder-coated in a nice wrinkle black finish to blend in well with the engine bay, and to provide a clean look. Once installed, you will get more horsepower, more torque, and reduced turbo lag.

Note: Proper tuning is MANDATORY for this intake. Please use the associated BigSF OTS Maps, or have your car tuned by a certified protuner. 

All of the required hardware, clamps, brackets, and seals will all be included to make this intake ready for the installation.

Rally sport. Quick fast shipping, box was beat up a bit upon receiving with minor minor bends at the ends of the intake pipe-but easily fixable Thank you Rally sport The intake itself now. Well crafted and easy installation, just be patient, don’t shortcut yourself, have the correct tools and make sure all fasteners are tight, everything lined up perfectly for me. (compliments the COBB AOS also) Performance. Updated Cobb AP to the correct ots stage 2 tune, definitely more turbo intake noise and bov boosshhh , I swapped stock trans mount to a group n and the car has a while different feel all together. I going to get a extra filter, so I can swap them out upon cleaning.

It was much more difficult to install then others I have done, but once in it looked great. Engine bay has a clean look and the OTS tunes from Cobb make it a great choice for the do it yourselfer looking to mod without the added cost of a pro-tune.
