Plenum filter sponge dimensions

My plenum sponge has disappeared! Don't think it was ever there when I bought the car and it certainly isn't now.

There's a rather good guide on how to replace it here: Intake plenum filter replacement (Range Rover 4.0/4.6/p38)

Prices seem to range between £6 and upwards which isn't a lot but then it is just a ****y piece of sponge and frankly £6 sounds quite a lot! Then I saw this:

Question is: what are the dimensions of the original? I think I'm better off just getting a large sheet of sponge and cutting them out as required as someone said they only last a year or two.

Cheers,

Damn. Just found them!

56 x 1 x 12 cm

32g

Isn't Amazon wonderful?!

12mm reticulated polyeurathane foam might do the trick, like this: http://www.airclean.co.uk/PDFData/Catalogue/AAC71 Air Filter Media.pdf

Anyone had any experience of using it?

Need to replace mine too so I'll keep an eye on what you find!

Just bought a genuine one. I'm going to make a cardboard template from it for next time and source some air-filter foam.

I replaced mine last year, needs doing again as it's full of holes !!!

You need to search for BTR9548. Paddock spares, Island-4x4, British Parts Online all similar prices once you add in the postage.

The one I got was from here: http://www.amazon.co.uk/dp/B00IA3A88S/ref=pe_385721_37986871_TE_item

I think some of the eBay ones worked out at about a tenner with postage or you could click and collect.

Nasty. Looks a bit of a fiddly job with the windscreen trim too.

I wonder if a glass-fibre matting would be a better choice if I could fit it in there.

Had the same problems myself, from memory the trim clips stayed behind when I took the cover off. Remove them and attach to the cover when replacing it.

That was it Alan, the clips pulled out of the trim the fun was getting them back in the right place and staying there to put it back, seam to remember a few cuts

If you drag the trim off from one end, the clips stay put

Going to replace mine with perforated metal next time.

Seem to remember a thread that suggested using cooker hood filter material - seems to be almost identical, when I get round to doing mine, I thought I'd use this:- CREDA COOKER HOOD Extractor CARBON filter CHARCOAL FITS ALL cut to size | eBay

Having that stuff exposed to wind and rain sunlight etc i would think it being biodegradable may ring alarm bells. Better with some stainless soffit mesh.

Pop into your local aquarium/tropical fish shop and get a sheet of filter foam.
When I got mine a couple of years ago it cost £4.50 and when cut into strips there's was enough to to three disco plenum's.

The was three grades of foam at the time easy seen as they are different colours, you don't want to get the very dense one as it may restrict air flow into the heater

I replaced mine with scotchbrite.
