Upper intake spacer?

I use to have it on my car before I got my Tb/plenum. I didn't notice a difference when I put it on there :shrug: I took it off when i put the TB/plenum on because it's already raised up and I didn't think I should keep it on there. I sold it to a guy for $25 shipped, he said he noticed a difference in his throttle :shrug:
 
i have a spacer for my t/b and plenum. i havent really noticed a difference. thought bout taking it off. but i guess i am just lazt when it comes to taking stuff of. putting on new parts is a diff story.
 
i had one b4 i bought my c&l plenum and it was smaller than the hole in the plenum so i figured it would probably just restrict the air intake so i left it off. so its still layin around in my garage with my stock nowadays :nice:
