Now available!   This new style Big Mouth cold air kit  is not replacing our original kit but is instead offering a less expensive  alternative to still have a cold air kit and even offers a more efficient path for the air to get to your turbo by eliminating a 45 bend. 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 adapter to hook to your 3" stock Buick, Chevy 3" LT1 or 3.5" LS1 MAF sensor.   Available in  polished aluminum.   All clamps and necessary connecters are included. 

VERY IMPORTANT!   For a complete turbo to air filter installation (minus YOUR MAF sensor), order one of our MAF pipes in 3, 3.5 or 4" diameters.  We can not guarantee this will work with other manufacturers MAF pipes.

This kit requires a bit more work to install than our original kit and might not be for everyone.  First off, the fuel vapor canister must be relocated to the frame rail near the steering box.  Very easy to do as it only involves drilling a couple of holes and bending the fuel vapor line that runs back to the fuel tank.

The 2nd thing that must be done is to relocate the vacuum ball that is mounted UNDERNEATH the inner fenderwell. Plenty of room to mount it on the bumper shock bracket, you will just need to extend the vacuum hose to reach it.

Next up, cutting a hole thru the inner fenderwell so the filter can be located outside the motor compartment.  The hole is cut in the bottom of the area where the fuel vapor canister was mounted.  This is easily cut with a Dremel tool with a #561 universal 1/8" bit.  You can see in the picture where the hole must be cut.  We supply a trim piece to go around the hole for a professional looking installation.

If you ever want to go back to stock, the fuel vapor canister can be put right back where it was and the hole will be covered up by the canister.  

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.
