Yup, doing pulleys you run the risk of breaking the vvti solenoid, header you run the risk of breaking the 02 sensor. Of course you could always snap your MAF trying to pull it out of your stock intake... Thing is all 3 of those breakable parts will cost you more than what you were replacing... lol

Or you could just install things correctly(read: not like a gorilla) and there's no risk of anything...
