This was in another thread recently=here are some better pics of it...
this costed like about 15.00 dollars from homedepot=a dryer vent tube{aluminum hose type not plastic}=simple pull the elbow off the fromt of the airbox{you have to usually remove the box to pull it off}..
put the hose in cut a flap in front rubber,sligfhtly tweak the a.c. lines out of the way and run the tube out>>>good for beter throtle response and mpg especially on the highway =about 19 mpg with 87 now
Also there's a pic of a cheap oil seperator made from a spectre see thru fuel filter=it's hooked between the pcv valve and the intake hose=it does pretty well in catching oil and stopping coking in the intake areas....
If any one has any more ideas ,I'd love to hear about them and so would the rest of the d-ranged gearheads on here.

 

Thanks for the pics! I'll throw this in the DIY section.
