I'd been looking at this Spacer for some time now and had been chomping at the bit to get it. Due to the economy on my side, I was finally able to purchase one. The only thing I did to it that was not in the instructions was: 1. Cut/Open the Circle Area around the Throttle Body side of the spacers Gasket, it overlapped the port by 1/4 inch. I thought it might decrease the performance by air restriction. All I can says is that it works for me! It has no turbo sound, maybe a little in high rpm in 3rd gear. But I have increased my fuel efficiency by this addition. It works. 1989 F-150 300-I6 EFI,5 Speed, MSD Coil, MSD 6A Ignition, single in-out Flowmaster(Soon to be Dualed Super44 Flowmaster)240,000 Miles and can run 47 miles on 1/16 of a tank w/13 gal rear tank!
