Wrangler Intake Horn Removal
 This modification is for the 4.0 liter 6 cylinder engine in the Jeep Wrangler (YJ). The pictures were taken of a rather muddy 1994 model, but I know it can be done on model years '91-'95. While you're at it, you might want to clean the throttle body. That is located at the other end of the 'hose' (as described below). FYI, this modification will not work in a '97 or newer Wrangler (TJ), that vehicle has a different air box.

1) Open the hood and locate the air filter box. The restricter you want to remove is inside the top piece.

2) Take off the clamp with a normal (flat head) screwdriver.

3) rotate the hose to one side, you can now see the lip of the restricter

4) With the same regular screw driver, pry out restricter

5) It is snug and you may want to use a second screw driver on the opposite side to help pry it out. If you still can't get it out, it takes about 2 minutes to disconnect 2 other hoses, and unclamp the entire airbox. This will allow you to get a better grip on the box and aply more force.

6) Put the hose back on the air box and squeeze shut the clamp.

This is the piece that was removed.
