Not sure if you want to go the cold air route on your 86-7 Turbo Regal?  We are now offering the Big Mouth Shorty Style air filter kit if you want to keep your air filter in the motor compartment. Parts included are a new 9" K&N air filter with a 4" inlet,  a short length of 4" pipe that connects to a reducing hose to hook to your 3" stock, 3" LT1  or 3.5" LS1 MAF sensor. A hole is drilled in the adapter for easy installation of the MAT sensor.  Your choice of a 3", 3.5" or 4" solid MAF pipe in polished aluminum.  They can be made to fit either integral inlet or removable inlet  turbos.  You need to let us know what type of inlet and what size inlet your turbo has so we can provide the proper size hoses.  All clamps and necessary hoses and air filter are included. 

So there you have it, a complete Big Mouth "Shorty" air induction system from the turbo to the air filter.  (Not including the MAF sensor of course!)

VERY IMPORTANT!  The 3.5" and 4" solid MAF pipes are for use with the LS1 MAF sensors only!  If you have the stock or LT1 3" MAF sensor I suggest you use a 3" MAF pipe. Our shorty style air filter kits use a 9" K&N cone filter with a 4" opening, this is where the BIG MOUTH name comes in.  You will notice the the filter sits right where the fuel vapor canister used to be.  The canister must be  relocated for this kit to work.  There is enough room to mount it directly to the frame rail with minimal effort.  If using the 3.5" MAF pipe please be aware that the clearance to the IAC is very tight.  I suggest you get a ANGLE BOSS from www.bopengineering.com to relocate it.  The fuel vapor canister MUST BE RELOCATED to the frame rail for this kit to fit properly!  

If you have any doubts on whether this system will work on your car please email me first!  

We now make all of our MAF pipes and cold air kits with silicone rubber hoses in your choice of black or blue.  Please be sure to pick the proper color in the order box.
