I bought one of these for the ED XR6.
IMO no difference.
At their respective narrowest points, the cross-sectional area (25 sq cm as I recall) of the XH snorkle is the same as the ED one.
The ED one would work better as the narrowest section is at the front and it widens from there.
The XH snorkle has a constant cross section (25 sq cm) through about 40% of it's length.
What did make a difference was fitting an EA intake tube.
Noticed a "snappier" throttle response and no noticeable additional induction noise.
I left the XH intake on as it fit better with the EL thermos.
The XR family ---->
Muzza: a XR8 AU seriesIII...bog standard :)
TBH: (the better half) drives an ED XR6 wagon (Mock Dev 4 160rwkw, JMM extractors, 4 electric windows, Ghia door panels in XR trim, rear head & arm rests in XR trim, Momo s/wheel with Cruise, EL thermos, EBGT wheels, etc) things to come soon = EECV upgrade.
