i got one just like that on ebay, but for like 10 bucks. i dont know if it did anything but it looks cool. i'd like to see a dyno graph of one to see if it really does anything
Those were popular about 5 years ago before the aftermarket plenums came out. We would use the spacer with our stock ported plenums and pick up a few hp.....they are worthless when used with aftermarket plenums and the ebay ones are not very nice....Steeda made the best one with a built in gasket.
