Fuel economy was the same after as before - but did just learn that tyre pressures were a bit lower than normal, so could be a minimal increase in economy.
Fitting was a bit of a pain - you need a "rivet-bolt" applicator. Managed to borrow one over christmas from a car dealership.
Had a tip today about Safari Snorkels. Turn the intake towards the back if you are driving through trees - stops the grill over the opening getting poked by sticks and breaking it.
Went out to an off road day today, with the people from the LR Club I found. Mel is going to post some pics on later :-D
