when i bought my cobalt ss someone had already put a CAI on it but i couldnt figure out if it was any good or not. im pretty sure its the j spec intake off of cobalt addition.. does it matter what brand it is or is it just the name? i was looking at the injen sp and the injen rd to replace it. does anyone have any ideas on what to go with?

 

in my opinion they all the same really wat could be the difference
i went with a ebay one for 80 shipped to my door in hamilton
cant beat that.....
