Now available! This new style Big Mouth
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
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.
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!
