  1. Works great on my 2015 Corvette C7 Zo6 Works great on my 2015 Corvette C7 Zo6. Install is a bit tricky because of how the airbox is mounted but nothing to the install really. Seems that the air filter has taken away some of the throttle lag off idle. No idea if it gave any true power increases since no before and after dyno runs. Sure something was added though since you can feel as if the car is moving quicker.

  2. Nice permanent filter Probably not a significant power adder, as mentioned in other reviews, but becomes a “forever” part on the car. Fit my 2014 Corvette perfectly… albeit not as easy an item to replace as in Corvettes of old (seems like all new cars are getting this way!). Need to unplug and remove many parts, wires and hoses to gain access to do this… but a feeling of a job well done afterwards.

  3. I think the computer didn’t like the oil on the filter Installed in my 2015 stingray. I think the computer didn’t like the oil on the filter. My quick throttle response went away and I felt a definite power loss. Installed a dry AFE filter and everything went back to normal. Go figure?
