Stock Intake Removal

1. Using a 10mm wrench, unhook the battery's negative terminal.

3. Remove the 2 bolts that hold down the intake box with a 10mm socket.
   
   
   
   
   
4. Using a 10mm socket and an extension, loosen the hose clamp attaching the accordian style rubber hose to the MAF sensor housing.
   
   
   
   
   
5. Pull up on the intake box and disconnect the MAF connection from the MAF sensor in order to remove the intake box.
   
       
   
   
6. To remove the intake bracket, use a 10mm socket and take off the 3 bolts holding it to the frame rail.  Then use a 12mm socket in order to remove the bolt connecting the bracket to the intercooler piping.
   
       
   
   
   
7. Remove the MAF sensor from the intake box using a 10mm socket in order to loosen up the four nuts.  When removing the sensor make sure the rubber gasket stays on the sensor and not in the intake.  The studs, nuts and sensor will all be re-used with the COBB SF Intake so put them in a safe place.
