Does the samco induction bend fit onto the standard airbox? why is it fitted?
drilled airbox Yay or Nay ?
Drilling holes in your airbox is just for added noise, unless things have changed since i was 17?
As for smoothing the airbox over on ukmkivs.net, i think they do that to smooth airflow and improve throttle response. That's on a turbo engine though and i'm sure the effects are placebo, much like a few 'mods' we do here on Cliosport.net
I was all over this mod back in the mid 90s
