Minor in performance as the increase in flow that it would allow is around 2%, but is smothered by the plenum chambers etc in front of it
But it will help, especially if you have a lot of carbon around, especially at idle and low throttle
Costs nothing and easy to do so no down side and potential for benefit
When you've modified the inlet system, its still the manifold below the TB thats the restriction, rather than the TB.
