First is there any difference between one companies throttle body spacer compared to another in reference to performance i have noticed that airaid now has one out and also street and performance electronics does too although the airaid is only for the stock intake. so im thinking of getting the street performance and electronics one along with the volant CAI that is now out unless u guys think better performance one's will be out eventually?

 

any thoughts greatly appreciated thanks

 

tb spacers are a waste of money. just provide a whistling sound...
