First off, Z1 made receiving this product awesome. It was fast and packaged well. I was very happy with the product itsself. It has the same quality build as say K&N. With the rubberized coating, so not to have vacuum leaks, proven to be an issue with cheaper versions. Also, the built in velocity stack was a nice touch, compared to some in the same price point that have a seperate velocity stack. This is a much cleaner look! I happened to stumble across this filter, simply looking for a blue filter, yet couldn't be happer with the product. From what i seen this is designed mostly for cold air intakes, however i installed mine on a 3" ram, that comes with a heat shield, and it worked perfect. I would totally buy this again, or suggest to others. Thanks Z1!
