I chose this system over the FSWERKS intake and K&N FIPK CAI system. Installation instructions lacked procedures to take off the wheel well splash guard and the splash guard under the front bumper. Once the old intake system was off, the new system was easy to install. Fitment of upper and lower intake tubing was perfect. Noticed a sharper throttle response, and well as about a 2 mpg avg increase, but this was with a small sample of data, compared to data taken with the stock intake system on. Not sure about HP increase, but the K&N system was dyno-ed at 11.85, so I assume its close to that. Overall pleased with the system. Hydrolocking isn't really a big issue as long as you don't drive through big puddles on that side. AutoAnything was prompt with shipping and no hastle with payment or receiving the product.
