As far as fitment, quality and overall looks I think hands down they are the nicest. I am throughly impressed with them!

As far as performance I have not dynoed a set yet. I hear mixed reviews from customers and until I dyno them I just don't know. What I can tell you is the filter location is closed off from the world and cold air will have a really hard time getting up in there. Now if you modified the bottom of the fender well liner by drilling holes in it to create perforation you will obviously allow more air to get to them. This is the goal, right! Cold Air!!! Now, it is very simple theory if you can keep the bends to a minimum, allow the filters to get cold air and mimic the stock tube size to keep the maf calibrated then you should pick up performance across the board. I think Ingen has achieved two out of three. If you look at their tube it looks like it was designed off of stock with a smaller diameter where the MAF is located. They also claim that it is dyno tuned and calibrated in the R&D process. The bends are also long sweeping bends that are as minimal as you can make them given the room they have to work with. Remember less dramatic bends, less restriction. The only one of the three that they do not have is the cold air factor. Like I stated before, the filters are hidden from the world. I know about the hydrolocking issue from water getting in them and this is part of the reason why they are where they are but has it really ever happened to anyone with this car???
