Plenum filter sponge dimensions

Got a new one. Taken the measurements and made a rough template for future replacements.

Had a look at the job this evening. Looks like the door rubbers will need to be stuck back on afterwards and they seem to be held on by some sort of double-sided tape - or is that a previous owner fix?

You keeping the measurements to yourself? are they top secret.;):D
 
Especially for Alan. :)

From left to right it is 22" wide. The shape is actually like an arrow where the point is 1/2" above the horizontal. The sides are 4 3/4" long. There is a central cut out at the bottom which is 2" wide and 2 3/4" deep. That just leaves the 2 bottom edges @ 10" wide.

Can you convert that to Metric for the younger generation? :D:D:D
 
Are there any problems if you don't fit the filter?

And at certain speeds you seem to get a harmonic that causes an awful noise. I hope that is what is causing it anyway. Will confirm once replaced.

All that dust and crap banging straight into the system cannot be good though.
 
Gonna do a writer up on how to replace it and any gotchas?

Already done here: Intake plenum filter replacement (Range Rover 4.0/4.6/p38)

Anywhere I see the word plastic and clip on a 20 year old Land Rover my heart fills with dread!

I've bought some waterproof double-sided tape to stick the door trims back where they might come loose. The screws look pretty easy.

It is just those clips that worry me!
