Air Intake Diameter?
 

Hi,

My 1999 3.3 Grand Voyager has had an LPG conversion fitted. To fit in some of the parts required, they have moved the air filter and it is now inaccessible.

My intention is to get hold of a cone filter (or one of those chrome cylindrical ones) and fit that in a slightly different place.

My question is, does anyone wknow the diameter of the air intake pipe that runs onto the throttle body as I will need to get some of the piping to move the air filter to another place.

I know I could just measure it, but it is such a sod to get to that, I only want to have to do it once :)

Thanks
Mike
