how much?

 

It's the carb plat on my truck not the TBSS... and I won't share that until I post my fastest Silverado SS with an Iron 6.0 block on N2O timeslip. Should be around Sep. time frame

 

But the TB spacer wont help you when it gets hot out It really does work, yes I'm from that company but there are far more people that say it works that have actually used it

 

they might work on other vehicles but not on the NBS 99-07 gm trucks, or any vehicle that has direct port fuel injection where the fuel does not flow through the throttle body

 

where is the IAT that you supply re-located? I would buy one if I thought it would work....I guess what is not understood is always questioned.

 

Its really up to the user, we recommend as far away from engine heat but STILL in direct inlet airflow. IE on the TBSS away from ambient engine heat inside the airbox but just after the filter for example. It's a simple device, but people are happy with it so far so we keep selling them
