I've had this intake for 4 years now and it still holds up well. My Z put down about +7 whp and +5 wtq consistently on the dyno after installing these over the stock airboxes, which is really close to what the manufacturer claims. Gained even more power after a tune. It sounds great of course with the loud induction noise during acceleration. These intakes come with a heat shield to help reduce heat soak. Very easy to replace the air filters. Solid product and I'm still happy with it.
