TRD modification ideas

[dingding]

I have a TRD airbox fitted with a 2bular exhaust system. It sounds amazing but been on  a long drive this weekend it started to get a little tedious on the motorway when on cam. I have the old airbox and can refit that but was thinking that would it be possible to tune the airbox by restricting the amount of airflow into the TRD ? 

The inlet is more than twice the size of the original airbox so could I just fit reducing cap of sorts no smaller than the original airbox for long road trips ( weekends ) 

Any ideas ..

It’s more to do with the lack of snorkel on the TRD. Which would be quite hard to do, with the triangular opening of the TRD.

So it’s not the sheer mass of air or csa it more about how it gets there ?  

I thought the TRD airbox was from a Lexus 300 or 400 ? So many be there is another part that would be fitted ?

Earplugs for long journey's... or refit the original airbox.

The Lexus equivalent to Toyota's TRD is F-Sport. So it can't be from a Lexus and be called a TRD.
