It's not hard to install. Took Carfixer about 20 minutes. Your assumptions on the install are correct. The boost increase was automatic. This is money well spent. K&N includes a guarantee that the kit WILL increase horsepower. You will not be disappointed.wildbill said:It sounds like this will be a purchase in the near future for me. You said that Carfixer installed it. Is it very hard to install? I am assuming that you remove the existing filter box and air flow tube to the throttle body and attach the new one, with a bracket for securing it. The increase in boost was automatic, correct? I mean that is what it is now. Easier air flow, so you get more of it. Right?? I feel that since I have gone this far (with the supercharger) what the hell is the difference with an air charger. That is small potatoes by comparison. Congrats on yours. :rockon:
