Yes - that's how pelican parts guide says to do it:

all back together now couldnt find a deep socket so had to use a wrench which gave me just about enough room to tighten enough but had to remove throttle body and intercooler pipes oil dipstick, the original wasnt that tight, quick drive no leaks..
hopefully this will solve my poor performance and loss of around 10mpg,

it worked...    my mpg has gone from struggling to get 36mpg to getting near 50 mpg, and a big jump in performance as well, car has never felt so strong,,,
