Re: Airbox Restrictor?
Nah it is restrictive hey, I read an article on here somewhere where they tested it. The best thing to do is to replace the restrictive bellmouth with a custom non-tapered one so that it still draws air from the centre of the filter. From memory it goes from 80mm at the entrance to 60mm at the bellmouth intake. I simply cut mine off and noticed a very slight improvement.
Eventually I will use a bit of 80mm pipe but until then....
