Regarding the CAI:
Needswings are teflon coated, shorter and relocates the MAF.
TVT is longer and in my opinion more difficult to install - easier to return to stock for dealer work etc.
The reason I state length is it offers the air more chance to warm up while travelling from the filter to the t-body.
Both are good - as for the same performance I am not willing to state my opinion.
Presumably you are aware that you cannot have the CAI AND airbox - it's one or the other.
If you want to keep it stock looking go for the TVT airbox where they remove the guts etc.
