I have done this on my 4kcsq, just like James Marriott.  Yes, they do
improve the pitiful US headlamps - at least the ones on the 4k/Coupes. 
With 9007's you get 10W of additional lighting on each low beam, plus
the pattern is better focused/distributed, with less "hot spots" and
more side/peripheral illumination.

Don't expect any miracles on the high beams, though.  They still can
only be described as "medium".

A groove has to be cut on the plastic base of the 9007 bulbs in order to
insert them in the headlamps and two wires have to be swapped - If I
remember correctly they are the low-beam and the ground.  Total cost of
the upgrade should be about $15 :)
