4x4 question.

JipJopJones · June 29th, 2007, 08:27 AM

Does anyone know what a good airfilter setup for a 4x4 is? I know that cold air is a bad idea with all the mud and dirt and stuff.... but I was wondering if anyone knew any good systems? I could go for a snorkel... and I probably will eventually but other than that, what can I do?

what 4x4 are thinking of? i can give you lots of information about snorkels for Land Rovers, but not for other types. have a look at http://www.safari4x4.com.au/ for snorkels and maybe http://www.motorsportworld.co.uk/fra...ir-filters.htm for filters

K&N are always a good choice too. personally i have never heard of cold air being bad for Land Rover engines, but other manufacturers might say that images/smilies/smile.gif

ARB is one of the best offroad equipment makers anywhere in the world. Here is the snorkel page at their site: http://www.arbusa.com/snorkels.php

I would trust ARB with my life. Down in Moab almost all the serious 'wheelers have ARB products on their rigs.

Cool thanks guys! I supose a snorkel is the way to go eh? I'll check out those links too.

Personally, I'd go for a Safari brand snorkel, with a unifilter brand oiled foam filter element. I work in mineral exploration in the desert here in australia, frequently in bull dust (google it) and thats the best combiniation.

The filter element is oiled with a sticky oil sorta like diff oil, and can be cleaned. Being oil it helps keep water droplets from passing through, and dust sticks to it.

Unifilters are also popular in rally.

If your looking at snorkels with the intent to cross deep water, then you should be also extending diff and gearbox breathers, getting a strap to hold your fan stationary whilst crossing (if its viscous coupled) or a tarp to cover the front of the car (this is to stop the fan blades hitting the radiator when they get in the water). Never turn a car off in water, as water will go back up the exhaust - some people here go as far as extending their exhausts up the back of their vehicles.

Personally I've crossed water that was above the start of my windscreen with the above combination, and I'm always in severly dusty conditions.

PS cold air is good for 4wd's, its just that the performance style cold air intakes on sportier cars arent a good idea

Don't forget changing the oil to check if water made it into the crank case.

ruuman · September 21st, 2007, 01:56 PM

and fishing out the various bent rods.... then tears as you've realised you've wrecked your truck images/smilies/smile.gif

Safari guard snorkels get my vote, they make loads of kits for different cars too. Just remember to check it's sealed properly after fitting.

Of and also check your fuel tank breather is working well and the cap seals well. This finished my day a few months ago half way up a river images/smilies/sad.gif

Snorkel is nice to have if you do some deep water/mud crossings be it fun or necessity. Depends really what you do with your 4x4. In most cases CAI will really do just fine. Went thru over-the-hood water couple of times, played in some mud - though not my cup of tea really so nothing too crazy. I've been using KN cone filters in my WJ (actually just 2 and second one has like 5 years on it and looks like total shit images/smilies/smile.gif

. I ditched the stock box, stuck the cone on top of the TB and, poked a hole thru the hood and stuck a scoop on top. Works like a charm.

matt2000 · September 21st, 2007, 03:48 PM

another quick thing if you have a petrol engine and plan to go through water, spray the plugs and leads on WD40, and try to seal the distributor. silicone sealant works well around the top of the dizzy cap.

also, if you have a modern 4x4, check the positioning of the ECU. if this gets wet, you will be stuck for a few hours while it dries out. move it to a safe place if you want a serious wading toy images/smilies/smile.gif

Blind_Io · September 21st, 2007, 06:51 PM

This is why diesels are the engine of choice for this kind of stuff. As long as they can breathe they will keep running.

true, but if water gets into the ECU any engine will die. give me a 90's LR 300Tdi any day for true wading power!
