Yeah, I keep 'em up on the highways.

(A little snafu in barcaldine when the belt on the servos compressor went and I let half the air out before I noticed. Had to gumby down the road to another joint)

Take the rack off and I'm sure you'll see a noticeable improvement, especially on your usage at 110. FWIW, 35's, winch, barwork, fully loaded inside with tools/passengers/camping stuff,, I get around 15-16L/100kms on reasonably flat hwy's (think pakky to sale type trip). That's a mix of 100-110kph. I'm happy with that.

As above the roof rack can add 1-2L / 100 at highway speeds. Knocked of 1.5L/100 when I took mine off and can comfortably cruze at 110 now. That extra drag is huge

The rack does look a bit like a wind anchor. I have debated taking it off. I don't really use it, but it seems a shame to lose the option?

In other news- I can't get the pre-air-filter duct for love nor money (well, I can get it for money, but I won't pay it for a bit of hose) so other options - Does anyone have a DIY solution for replacing the ducting for the Pre Filter, or suggestions for aftermarket prefilters altogether?

[threedogs]

got a pic of what your trying to do.
Roof rack will lose 50ks a tank off your range

[BigRAWesty]

Where the arrows are there should be some duct to collect air from the wheel arch and go to the air filter.
New spares are stupid $$$. I might swing by a wrecker, but are there other options other than just trying to replace it with the original stuff?

[BigRAWesty]

The td gq draw air from the hole in front of wheel arch. We also run a vertical pre filter..
Our output hose is 3" so you make able to get some silicone bits and a reducer to take it down to what you want.

[BigRAWesty]

And just noticed you are a backwards driver lol. Left hand drive.
It's all backwards to us lol..

You can see our vertical pre filter bottom right of this picture
