Finally doing some much needed maintenance since I have 120,000 + miles on the truck ... new tires , shocks , plugs , clean the throttle body , front rotors and pads etc .
Looking at the new throttle body gasket/spacer that my VIN number says I should use and have a question . There are air directors/fingers on the spacer 180 degrees apart . One set is shorter than the other set . Did a search to find out which goes on top .... the short ones or the long ones and found nothing .
Anyone know what the correct orientation is ?? Reason I`m asking is the current gasket is paper only ( replaced by someone long ago ) and I want to replace it with the "correct " one .

Thanks
