K&N air filter

Yep thats why bigger diesels have dust indicators not hourly schedules,, they work best just before replacement.. [wink11]

So, yeah — my reading of that post (which is bloody excellent by the way!) is that there’s a negligible difference between clean and dirty paper filters, for the cylinder-style used in the tests. I don’t know if the same applies to the flat filters used in the D3/4 engines.

Whether it does or not, I’m pretty comfortable with the filtration performance of a new filter… happy enough to change it regularly when I’m servicing the car anyway :)

I haven’t found a genuine (or premium aftermarket) service kit for my Disco 3 for anywhere near that locally. I’m buying genuine kits from the UK ‘cos of the significant Australia tax you pay on genuine parts buying locally.

I just ordered a genuine service kit from Island 4x4 for about AUD$150 + shipping. Haven’t seen anything close to that locally, I don’t reckon. Happy to be shown otherwise, though!

Cheers,

Same here. Genuine kit from Island 4x4 $150. Mix of genuine and aftermarket from my indie $250. If I could find anything close l would buy locally.

Get onto Mario & Heather and see if they do a kit for the D3/4. All the filters in the kits I've got are Mahle brand.

Yes, and that goes for ALL air filters.
The more heavily loaded the more efficient they are. Right up until pressure drop becomes too great and it impacts performance and fuel economy.

I reckon after re-reading all the material here, I might change my practice slightly and change the air filter less frequently. I’ll still buy the full service kit and just pocket the filter as a spare. Will come in useful for those dusty outback trips.

Great discussion and that thread by isuzurover is brilliant!

Aftermarket from All Four x 4 (might be worth an email to check brands) $156.00

https://www.allfourx4.com.au/epages/...roducts/LFK07A

Genuine $202.50

https://www.allfourx4.com.au/epages/...roducts/LFK07B

Depending on the postage from the UK, (and from All Four x 4) could be worth a look. [thumbsupbig]

Bargain, not. Especially when even they say the sum of individual parts is $195, plus the Genuine kit doesn’t have a genuine pollen filter or sump plug [bighmmm]
