Are CAI's worth it? I have a C & L 80mm right now, and I'm not sure if it was a good idea or not. The MAC website says you have to add length in front of the MAF if you remove the airbox, otherwise you lose power. Thoughts? Who makes the best CAI?

Dont know about the C&L but I recently put my car on the dyno with and without the MAC cold air.
Stock-248
Stock w/K&N drop in-250
Cold air kit from inside fender to throttle body-253
Cold air kit from inside fender/stock from mass air to TB-262
As you can see I lost 9 hp with the complete kit. I called and talked to Idle Wild Racing(Doug Magrum's shop) and they told me they have experienced the same thing and the reason for it was because it MAC pipe was the came size from the MA to the TB. The stock pipe is bigger at the MA and necks down at the TB and this promotes air velocity. So thats my experience with cold air kits.
