Air box for buggy?

[rcx132]

I've been struggling finding an air box for my 4x4 buggy build.

I've seen these Donaldson brand boxes, designed for use on plant. I like the simple easy to mount design with simple inlet and outlet making them easy to plumb, and cost £75 which for a high end German product seems good. But I don't like that they use a double filtration system which will be expensive to maintain, and the spouts are 76mm and I need 70mm to avoid adaptors. I've seen that mini excavators have similar boxes but they rarely advertise the inlet size.

I'm after something that has a simple shape making it easy to mount, and with an inlet and outlet spout so that I can attach a snorkel. And decent quality, there are some common aftermarket boxes but they don't look waterproof enough for 4x4 use.

I'm open to ideas.

Land rover, the tube size varies and I cannot tell you which ones are 70 but fairly sure a number of them are in that region
Find something for sale and ask them to measure it
The Older defender boxes are metal so you can weld brackets on but think the inlets and outlets were 60 or 65mm

Scroll down a bit and it gives you dimensioned schematics.

The first chapter is calc sheets for what system you need

May be of use.

Older Ford Ranger/Mazda trucks have a neat airbox, 250mm ish cube with a 70mm inlet. Not too spendy on a filter.
Can take a snap of one if you want.

Sounds promising. I welcome a snap

@James1979 I'll have a browse through that catalogue, looks useful.
