yeah I got a Cold-air off ebay too. I've noticed a jump when I'm on the gas. Looks good sounds even better. If I catch it just right I can make it sound like it's a blow-off valve for a turbo.
Cheap CAI
Get a new length of hose run it from the front connector and either close off the second hole or throw a $10 air breather from wal-mart on it.
SEE THE ATTACHED IMAGES. (NOT THE GREATEST QUALITY)
1. What the engine used to look like.
2. What it looks like now.
A= Air-breather from wal-mart. fits perfectly
B= 90 degree air compressor fitting trimed and bored out (if you need one let me know, and I can make one for you FREE) use some fuel line hose to make up for the short distance on the stock intake hose (intake to crankcase) (you won't need this if it comes with new hoses)
C= the staright fitting will need to be heated in a microwave for a few seconds then quickly attached to the MAF sensor before it converts back to it's original size. It's a bit small and heating it makes it stretch out so you can work it on. but do it quickly.
that's all.
