I'm currently renovating my 90's heater box which has turned into a complete overhaul of the whole heater/ducting etc etc. After removing the dash I found 35 years worth of rust/dust/coins and parking receipts all in the air tunnel that also forms the dash. Now with fresh paint on all metal parts, I decided to insulate the air tunnel. What I also would like to do is fit a pollen/air filter so the dust and muck doesn't enter in this area again. I have done a search on Google to find Devon 4x4 do a D44 cab filter that sits on top of the intake. I want to keep my 90 looking original so this D44 wouldn't be suitable for me.
I have measured the heater box intake at 112mm and a cone filter would fit, however it wouldn't fit inside the air intake duct, so again its looking like a difficult task to do.....
Would anyone have any ideas that may work?

Sorry,way beyond my knowledge. Best of luck with it though.
Do the last real Defenders have one fitted?

Yeah, best of luck - I think the 'dust and muck' may be what's holding my bulkheads together! Shocked

The heater in my 90 is pretty much non existent. The previous owner looks to have repaired it at some point but I want to replace it. There is an upgraded matrix available which I want to use as and when I replace the heater unit.

I always found the heater in my old Series 3 much more effective than the one in the 90.

Reading the Australian forums, its a problem over there with dust. They use old tee shirts and socks to cover up the intake Cool
I have ordered 15mm air filter foam from a motorcycle parts supplier. My plan is to fabricate something circular out of aluminum and fit inside the intake, just before the heater box. With future maintenance in mind, this will be removable. Its worth a try anyway.

One question I have - My intake (MUC2419) isn't fitted with the Spacer-tube-flanged condenser (MRC8642) as listed and shown on LR parts website. It states that this part is from 1987-2006. My LR is a 1985. To me the part must be missing as the intake does not fit onto the heater box. I have the seal/gasket but its useless as the 2 parts don't fit into one an other. So - Can anyone confirm if they have this part on the earlier 90/110?

My parts catalogue shows the following for our early 90's in order of connection :-

MUC2419 (Intake)

MRC8642 (tube flanged)

MRC8378 (Seal Heater)

Fan / Motor box

We have had another foot of snow so I'm not venturing out today, but can confirm fitted to my 1984 if required tomorrow, but the parts catalogue is quite clear that these are the parts that should be fitted.
