I went with these guys because they had done many snorkels on Jeeps and they used my car to pull apart to work out how to do it. The large head certainly drew in a lot of air.
I am now on my second WK2 - a grey Limited - and I don't have a snorkel on it. I have redone the battery box/fridge/compressor setup for it.
I changed the battery box to a Korr one and the compressor to a twin piston Thumper. The twin Thumper is very fast - pressurising the air tank to 125 psi in around 30 seconds instead of minutes for the old Bushranger MaxAir. It pumps up a 265/60R18 Hankook from 0 psi to 40 psi in two minutes flat.
The battery box is brilliant - it has 4 x 50 Amp Anderson plugs and 1 x 175 Amp Anderson plug as well as 2 x cig sockets and 2 x 2.1 Amp USB's plus a master switch and VSR built in.
I have a Ctek D250S Dual inside the box, so I don't use the VSR.
The battery box, fridge and compressor/air tank all fit neatly on the back.
The Waeco CF45 litre fits in perfectly and the cover I simply turned inside out so the silver is on the outside. I know you can reflect heat, but I don't think you can reflect cold, so why have the silver on the inside???
