no paint was used on them. </div> <div> Some manifolds which had been installed at the engine plant, could have been “oversprayed” engine color.  </div> <div> After cleaning, use either a high-temp clear, or a cast metal color for the most authentic look.</div> <bR> <bR> <bR> <div> <B><U>Picture 1</U></B></div> <bR> <div> The items you will need:  1/8” pipe thread tool, 8 ea-1/8” brass hex head pipe plugs, hex hand wrench, small hammer. </div> <bR> <div> <IMG SRC="ae6ec710.jpg" border=0 width="492" height="369" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <bR> <bR> <div> <B><U>Pictures 2 & 3 </U></B></div> <bR> <div> Remove the external tubes from your exhaust manifolds, and push out the small internal air extensions inside the ports.  </div> <div> Push them out from the back with a hammer. </div> <bR> <div> <IMG SRC="ae8ec710.jpg" border=0 width="492" height="369" ALIGN="BOTTOM" HSPACE="0" VSPACE="0">  <IMG SRC="aeaec710.jpg" border=0 width="492" height="369" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"> </div> <bR> <bR> <bR> <div> <B><U>Picture 4</U></B></div> <bR> <div> These small tubes are readily available, and cannot be seen when installed.  </div> <div> If they are damaged, discard them, otherwise save them with your other parts to stay with the vehicle.</div> <bR> <div> <IMG SRC="aecd25d0.jpg" border=0 width="466" height="349" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <bR> <bR> <div> <B><U>Pictures 5, 6, 7</U></B></div> <bR> <div> The holes that the tubes came out of are exactly the right size for a 1/8” pipe plug.</div> <div> Use your 1/8” pipe thread taper to thread the smaller hole way down inside.</div> <div> Do this from the front, using the larger hole as a guide to keep everything straight.  </div> <div> Thread the entire way through, but don't go too far, because you want the plug to sit at the bottom of the hole. </div> <div> If the tap peeks through about 3/8”, that is enough.</div> <bR> <div> Use plenty of cutting oil, and clean your tool frequently.  </div> <div> Do this for all eight of the A.I.R. ports.</div> <bR> <div> <IMG SRC="aeeec710.jpg" border=0 width="492" height="369" ALIGN="BOTTOM" HSPACE="0" VSPACE="0">  <IMG SRC="af0ec710.jpg" border=0 width="492" height="369" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <div> <IMG SRC="af2e0680.jpg" border=0 width="480" height="360" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <bR> <bR> <div> <B><U>Pictures 8 & 9</U></B></div> <bR> <div> Coat the plug-threads in red Thread Locker or Loctite, and install them down in each port from the front.  </div> <div> Make sure they sit properly all the way down inside the openings.</div> <bR> <div> If you are forced  to use the square-head plugs (available from Home Depot),  </div> <div> you will need to tap from the back and inset from behind, in order to leave room for the tubes in front. </div> <div> I like to use a internal hex plug found commercially.</div> <bR> <bR> <div> <IMG SRC="af4e36a0.jpg" border=0 width="483" height="362" ALIGN="BOTTOM" HSPACE="0" VSPACE="0">  <IMG SRC="af6e46b0.jpg" border=0 width="484" height="363" ALIGN="BOTTOM" HSPACE="0" VSPACE="0"></div> <bR> <bR> <bR> <div> <B><U>Picture 10</U></B></div> <bR> <div> Install your tubes back over the top of the plugged ports;
