K&N Filter for 1991 RR ???

[BlackCSK]

Has anybody had experience in replacing the OEM Airbox and Air Filter with a K&N Filter? Specifically the K&N 57-0050 model which is customised as the replacement airfilter pod for 1988-1994 3.9ltr Rangies. I'm looking at doing this but would like to hear from someone else who's tried it - hopefully with no problems at all.

If you do a search on this you will find some "interesting" threads.

Wildly divergent views on fitting K&N filters to Land Rovers.

Nice first post topic!!!

Sorry - I should have also said welcome :D

Hi & welcome
My 1990 RRC came with a Pod air filter already on it .... As the previous owner had removed the round can air air filter and stuck this on

It has been hose clamped directly to the alli body of the MAF (take it off and you can see the mesh wires of the MAF


I don't think much of it ... The motor runs OK ... You do hear a constant slurp (air sucking) noise of air all the time, so it is noisy .... Would NOT use it in fine dust conditions

Pods only keep out rocks and tree branches, so be more than a little careful where you go.

Not a particularly good dust keeper-outer!!!

And welcome!!!

FWIW If you want to improve airflow fit a properly plumbed in Deefender 300TDi air filter assembly. Read Isuzurover's excellent thread on airfilters - once you have read that I don't think that you will even consider a K&N set up. What have I done - on my 300TDi Discovery I have fitted a Defender 300TDi filter , on my Defender with an Isuzu 4BD1T fitted I am using the genuine Donaldson filter, I am hoping to build up a special classic Rangie shortly - 93 model 3.9 V8 - DV, I intend to use a Defender 300 TDi filter assembly. The K&N set up might be alright for the race track, but does not provide adequate filtration in dusty conditions.

G'day BlackCSK :)

Welcome to AULRO :)

Would that happen to be CSK-011, by any chance????

saw it a Qld 60th gathering at Gold Coast, but may have missed it a Cooma.

It is one nice vehicle!
cheers

Actually my CSK is one of the Australian 4 door releases.
There were 50 of them - 25 were black - 25 where white - mines one of the black ones.
All were built in the UK in September 1990 and released in Australia in July 1991.
They were marketed as "special' at the time but they were really a cosmetic upgrade to a Vogue SE.
In effect these 50 Aust release CSKs are the equivalent of a 1991 build Vogue SE, but built in 1990 (i.e. a 1991 Vogue SE proptotype built 6 moonths in advance), with every Australian option included plus the following
- beefed up factory stereo unique (which is actually pretty good)
- black and gold pin striping unique only to the Aust release CSK (whoopee!)
- a "CSK" decal on the tailgate and each side (whoopee - ye har!)
- first Australian RR to be factory painted black (again whoopee! - but it does look bloody good when its polished up!)
There is an incorrect rumour that the engines were spannered up - they are the standard 8.13:1 comp ratio 3.9 EFI V8.

Nevertheless it was sold as a CSK - and for what it's worth if you check out the Red Book for 1991 RRC, the CSK is listed separately as the next up from a Vogue SE.

I've had it since 2002 and love it.
I've also had a 1993 RRC; and also a 1971 Series III Landy into which I shoehorned a Holden 253 - however both these are now long gone.

Actually the reason I am wanting an alternative air filter arrangement is to get the original factory air box (round) away from the front corner of the engine bay so that I have the room to install a second battery - So if anyones got advise on this it would be appreciated.

All you have to do is cut off the intake snout . If the battery is very high like my 95AH AGM, maybe think about a snorkel. AFAIR its not necessary to move the filter back.

I cut mine off at the back of the filter can so I still had the metal attachment to the MAF and the support.
I agree that in dusty conditions they may not be the best, but there is a wrap available for them to go over the top if you run in dusty conditions regularly.

I did this for exactly the same reason, but you will also have to fab a mount up to move the PS reservoir also. Will take a pic tomorrow and post it up for you.

Pics of how mounted. The std aircleaner is too long and yes you do need remove the main can if you want to get a dual battery in. The downward angle of the std filter puts it right in the place of the battery mount area with the intake horn almost against the radiator support frame.
I still want to make a cold air box at least.

As mounted. Bent filter is from hitting the roo a few years back.

Closeup of MAF intake pipe. The airbox was about flush with the back of the filter.

my 3.5l twin carb, I mounted twin K&N pod filters and noticed a differnce in acceleration, it was much smoother and constant when putting the foot down. Also changed all the belts in the engine which made it a bit quieter so maybe that helped too. I don't drive in dusty conditions much, mostly towing the boat and the odd bush bashing trip to find new fishing holes.:D

Hey Mate - Matt here from perth. Its been a while since this post of yours so I hope you're still around. My question would be the same regardless, but as a point of interest - I was interested to read your summary of the CSK RRC in Australia. A photo of mine is attached. You can just make out the faded decal on the tailgate. Easier to make out is the bogged Lancelin, WA police divvy van 50 yards onto the beach with 40psi. Even my dogs had a giggle p*ssing on one of the tyres before they could deflate it. The chap I purchased the CSK from 7 years ago said it belonged to the Perth dealer new and was stored for around 10 years. Other RR officials confirmed the 76000km on the clock when I bought it and it now has 98000.

Anyway - my question is exactly the same as yours - I want to clear some space for second battery under the bonnet - move the airbox possibly incorprorating a snorkel. If I go with second battery in the rear, I would still like to see how she goes with more air than the can would seem to provide.

Have the 8 years since your post been sufficient for you to complete yours? I would live to see any photos and hear any ideas.

Hope you haven't gone Toyota or anything silly and you're still knocking about in this forum.

Cheers
Matt

Hey Matt,

There are a bunch of threads on here regarding RRC dual battery setups in the engine bay as well as the relayed airbox / snorkel stuff. Whilst the snorkel bit may not interest you, the underbonnet modifications which enable the use of the snorkel also have been discussed in several threads. Below are a couple which may help.
