Is there a bigger better bolt on throttle body for the mk1 vrs that's fly by wire off another car like audi s4?

 

Just wondering...

I have zero clue but it'd be good to know for future reference but increasing the throttle plate size will have a knock on effect through the entire intake system I would I thought

Others fit but pointless mod :-)

Gains are only seen on 400bhp upwards but to big can cause issue :-)

I do know one thing about the TB' s on these... And that they should NEVER be bored out...

 

Unlike in the bmw world where boring out throttle bodies is common place and good for gains ect.. Not on these tho apparently
