THE BEST SIDE OF 4AGE 20V ITBS

investigating the above mentioned picture the take off going straight down on all 4 ITBs will be the outlet from the small hole just by the throttleplate (on my ITBs there is no vacuum there - i.e. ineffective)A bit of hose on your ear, holding it at the very same spot for every one's 'hiss' for comparison - Appears equivalent, they are equivalent.
