No Difference in Performance!
Very disappointed in the quality and performance. The spacer is a tad too large and the holes are not quite the same size as my throttle body. Needed a rubber mallet to get everything to work! Once on, although Jet says it doesn't whistle like the competitors, it sure as heck does! Very annoying and like I said, no apparent gain in performance or mileage. Save your money on this one!
