Features & Product Details

RallySport Direct is your number one source for quality upgrades and enhancements brought to you by COBB TUNING. 


This 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.




  • 3" Mandrel-bent aluminum tubing
  • Powder-coated black finish
  • Black airbox with a laser-etched logo
  • Dual cone, pre-oiled green filter
  • Includes a plug and play MAF extension harness
  • Includes all of the required hardware to complete the installation



  • Proper tuning is MANDATORY for this intake
  • Please use the associated Big SF OTS Maps, or have your car tuned by a certified pro tuner

    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.

    4out of 5stars

    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.
