Thanks for the comments & advise. Although using K & N filters on my previous vehicles, I think I'll give it a miss on the D4. Too many hard earned $ to take a chance for a few extra Kw that I don't think is needed on the 3.0Lt anyway.
I also agree that the higher air intake maybe better for deep water crossings, but in thick dust, there is probably not much difference.
More opinions welcome, but at this stage stock is the go.
Cheers, Craig

I use to work in a Hospital and all the operation theaters had HEPA oil filters. I was under the impression that these filters trapped air particles 2um and above.

HEPA (High Efficiency Particulate Air) filters remove 99.95% of particles. No automotive air filter would conform to HEPA standard when new.

Air filters are not sieves.

Does this mean that the K & N air filter is ok to use?

K&N would probably be ok if you only drove on sealed roads about town. All bets are off once you hit dirt... they're really designed for filtering less (less flow resistance) to give higher performance - not for longevity of engine. As the saying goes... horses for courses.

I had a Safari Snorkel fitted to my D3 yesterday.
After watching it being fitted I now have an appreciation of why they cost so much.
The quality was good & the instructions comprehensive.
It is not a job I would do myself.

I purchased the snorkel for ARB for $484.00 with LROCV discount & then had it fitted elsewhere.

BTW - thankyou to to the fitter for a great job.

Regards

Just a quick one to add my experience to the snorkel story: in the last few weeks I imported a genuine LR RAI from the UK (for less than half what I'd been quoted here, freight included) - and then had it fitted by my local dealer. Fitting cost two-thirds of the purchase price - but overall still a significant saving. I went with the RAI because I have no desire to go wading rivers, but wanted to get my air intake up above a lot of the dust I encounter out in our goldfields & mid-west. And I figured I'd stay genuine where I could, to reduce the weasel options in the case of any warranty issues...

Not the most handsome piece of equipment - prompted one of my teenage daughters to ask "what is that big black ugly thing you've put on the car?" But no noticeable increase in wind noise - well, there was none before - and there's still none that I can hear. And to be honest, I don't mind the look - very LR.

Hi All, interesting chat about snorkels etc. I did read that unifilters CLAIM to filter down 4um with a 24% increase in air flow. I have always run uni filters in everyting {4x4, car, motorbikes} and have never had any problems. Anyway just a thought . For more relevant reading got to the unifliter website.
PS seems unifliter don't make a filter to suit a D3 or 4

Any filter manufacturer who claims a specific micron size for the air filters clearly has no idea how air filters work.

Btw - soot in the oil is MUCH smaller than 4um and still does engine damage.


No, what gave you that idea?

I've braved it, I've ordered 2

Sorry, not D3, but 110
