I said that too. Promised myself and my girlfriend. That didn't even last 2 weeks before I got my first package in the mail!!
Same here, I swore I wouldn't touch the car, not even an intake! Said it to all my friends. Well that didn't last too long. At least I'm still lightly modded but now I'm thinking about the AP and possibly a motor mount......
Once you get used to the power and know that 15-20 more is just a few boltons away, it's hard to resist.
