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 <B>not</B> work in a '97 or newer Wrangler (TJ), that vehicle has a different air box.</div> <bR> <bR> <DIV ALIGN="LEFT"></DIV> <div> 1) Open the hood and locate the air filter box. The restricter you want to remove is inside the top piece.</div> <bR> <div> <IMG SRC="143f0400.jpg" border=0 width="240" height="320" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> 2) loosen the clamp for the hose with a regular (flat end) screwdriver</div> <bR> <div> <IMG SRC="14440f00.jpg" border=0 width="320" height="240" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> 3) rotate the hose to one side, you can now see the lip of the restricter</div> <bR> <div> <IMG SRC="14540f00.jpg" border=0 width="320" height="240" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> 4a) With the same regular screw driver, pry out restricter.</div> <bR> <div> <IMG SRC="14640f00.jpg" border=0 width="320" height="240" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> 4b) It is snug and you may want to use a second screw driver on the opposite side to help pry it out.  You might want to try removing the air filter box and pull the SOB out with plyers.</div> <bR> <div> <IMG SRC="14740f00.jpg" border=0 width="320" height="240" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> 5) put the hose back on the air box and squeeze shut the clamp</div> <bR> <div> <IMG SRC="14840f00.jpg" border=0 width="320" height="240" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> Your done, enjoy the extra oomph!</div> <bR> <div> <IMG SRC="14a40f00.jpg" border=0 width="320" height="240" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"><IMG SRC="14b40f00.jpg" border=0 width="320" height="240" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> this is the piece that was removed.</div> <bR> <div> I have heard from a few people that this adds 10 hp to your Jeep and also slightly increases gas milage. If you're like me then you don't notice much of a difference.
