This is essential very untrue. Many aftermarket induction kits providing they are enclosed systems have proven gains to performance. The phase 1 clio 172 airbox with upgrade filter has proven gains of atleast 5 bhp with dyno evidence.
Can anyone help?? I have a twingo rs gordini 133 and ive looked through the manual and ive seen the renaultsport multifunction display with the throttle response meter and lap timer and other things. Can anyone tell me if this is available on my car?
