Right after i bought my grand prix i realized that after a small trip on the highway it felt like the engine bay was on fire. This made my aftermarket cold air intake completely obsolete seeing it was just cycling hot air into the intake making the engine heat up even faster. I figured a heat shield and cold air ram would be a great solution to the problem. I also didnt like the fact that the stock air box held the pcm so that when you install an aftermarket cai it would have to float freely in the engine bay unless you pay zzp $40 for a pcm tray.
step 1: tear out and keep all parts from the stock air box and cai.
note that the hole in fender-well will be used for the cold air ram
step 2: cut airbox down to use as cold air ram using stock hole
Step 3: measure the open area and use a cardboard pop or beer case to mock up the area needed to fill, then transfer those measurements on to a sheet of sheet metal. cut and bend into desired shape.
check fitment before installing the rest of the parts into the box
i made the height too short so that the pcm didnt fit with wires inside box. solution comes later.
Step 4: cut hole and install cold air ram into the box.
step 5: cut out a chunk or the stock intake rubber hose and a hole in opposite side of box to use a a seal for the stainless pipe into the box.
i found out later that trying to get everything into the box before installing it was nearly impossible, so i cut the top off of the box. make sure to cut high enough towards the top as to not compromise the shape/ structure of the box. (i didnt cut high enough and cut part of the side out on accident. made the install a little more difficult but still worked.
Step 6: use a piece of plexiglass to cover the top of the box. also cut a hole in the top of the plexiglass to fit wire onto the pcm. I did this so that monitoring the condition of the filter was easier then tearing everything apart just to check it.
Step 7: install all parts and step back to admire the final product.
thanks for checking out my build.
