hi, is anyone using or have a JC50 megaflow filter ? i need the dimentions / drawing of the backplate?

Have you tried ringing ITG directly? If not, give them a bell and ask for Adrian. Really helpful guy and I'm sure he'll give you the dimensions you're after

Or use the power of the internet...

Hi Stu,
Thanks for finding that website, I was asking about ITG filters a couple of weeks ago and this is the sort of thing I was after. I'm hoping to use them on a pair of SU carbs on my Rover V8 and I was wondering if you have come across any ready-reckoner's for sizing the filter for a given engine? I obviously don't want to undersize the filter and limit performance but on the other hand I don't want them to be huge since I am intending to have them sticking through the bonnet. The website keeps referring to the "popular application list" but I can't see it - can you?

Cheers,
Craig.

How about here then chaps?

But basically, fit the biggest airfilters you can....
