Just to clarify things a bit - I Think dcstraight means the AU Series Tickford XR8 Snorkel for his EF-I6

Herrod is right though in saying that it wont fit an EF/EL V8
As for the 2 Holes, they weren't really that hard to drill,
as what the Doco said, use a 3mm bit, and drill down only a couple of millimeters.
If you have a drill, and 3mm Drill bit, its honestly about 5 Minutes worth of work to fit.
If it saves you $25 or so Dollars, then buy yourself a new 3mm Bit, and go for the AU version.
Just my 2cents worth.
P.S. you will see much more in terms of gains fitting cold air induction, from the bottom of the airbox, routed to the front air dam of the car.
I can't do this (properly), as the ABS sensor on the EF is directly under the Airbox, and my front Air Dam holes have cornering Lamps in them, and the Front Radiator duct has the Airconditioning thing there ! :oo1:
