I want to get some pod filters top drop over the ones being fitted to my TBs but dont know what size diameter is needed. Thinking about something like this

its only for racing so looks unimportant - just protect the engine

That's what I ment, you will need to be carful not to spoil the effect of the stacks with the filters, it's really something you should setup on the dyno as it will have a huge effect on the fuelling.
