I have fitted the EL GT/XR8 snorkel to my EL V8, it does improve responsiveness. For all of the V8 owners, the AU XR8 snorkel (with the Tickford wings like the one on Xyphoids car) does not fit onto the EL V8, I have tried. So I had no choice but to use the EL GT/XR8 one and it does seem to have a bigger mouth and neck on it.
Go The Roaring Fords !!
