$399 for the intake. i believe they require you to purchase the chip as well along with the intake with a stage II software download. so its $399 for the intake, $399 for the chip, and $399 for the stage II softeware.
thats okay woobie. as for the software, you will need to purchase only 1, not both. if you already have stage I, then the stage II upgrade is free of charge. if you do not have a stage I software, then you only need to purchase the stage II download.
Actually, I'm pretty sure you can buy the intake alone, without purchasing anything else. I bought the intake alone, and then added on the exhaust and the software afterwards, but that's at the BMW store in Cincinnati. I don't know the "rules" where you live.
