Thanks for the compliments guys. The CAI building is going kinda slow right now. I've only shipped out about 4 of them. I'm going to change the design a little so that it is a better fit and much easier to build. I have to spend the next two weeks on my turbo though. so after HIN on Aug. 3rd, I'll be fully commited to the CAI's again. The new way I'm building them I will be able to make them faster so the wait won't be so long. Thanks again for the compliments. Also, I decided not to use the recirculation hoses on the intake. All they do is suck hot air from the motor so it will start easier in cold weather. This is only needed after the car is like 5 or 6 years old and you have around 100,000 miles. The motor doesn't want to start as easy then, so it needs help by using this warm air. But if you are looking for a little more power, this hot air won't help. The filter is like $5 to $10 at Autozone or Pep Boys. It looks like a little air filter.
