I had mine over a yr and mine warped so much i had to keep tightening the clamps every week. I just got sick and tired of it one day when i went out to lunch from work the car acted funny and my AIR/FUEL gauges read WAYYYY lean i immediatly pulled over and found the rubber part totally off from the plastic piece and ordered a different one from steeda, not to mention the first one i had actually came apart at the seem. I had bought the TRU cold air style one from JLT to begin with...not happy at all with them.....
