Think I've found a possible cheap snorkel kit for the KK.
A Pajero NM, NP. Seems to have the right traits for an inside the guard fitment. Toss away the 'J' bend, use the low profile Z tube to get to the airbox and then custom make something into the airbox with a flange. Would need some 'straightening'.
And best of all it's $88 shipped)!

I might just have to get one for that money and give it a go. Having a good run this week. I also got a snorkel kit for my Pathfinder this week, usually $495 + freight, got one from NZ specifically for my diesel, for $195!
