I have tried at least a dozen different CAI setups including the original WMS Velocity tube a few ago and this latest kit is by far the best looking and performing out of all of them. I always thought I could compete by building my own CAI but in this case, nope! My home built kits worked good but not this good, with looks. I had planned to go with a new CAI kit by Volant but after 4-5 months of waiting and then lack of response from them ( ) I decided to move on and go with the new WMS kit that a couple of my fellow Cobra mates recommended. Given I have a strut tower brace this was my only other option at this time for what I wanted. As for the installation it was a piece of cake except having to install the filter from underneath which barely fits in the fender. Otherwise fits like a glove and the response and pickup it has provided my car is amazing and very noticeable . My fuel trims have never been so stable and near zero before as they are now, at least on my car with my modifications it seems to be the perfect combination. I plan to dyno soon establishing a baseline of all my accumulated modifications over the past year before my SCT tune.
