4.2TD Patrol - To snokel or not?

Submitted: Monday, Aug 01, 2005 at 16:15

colski

Hi all,

My old man has a GU 4.2TD Patrol, does lots of caravaning and country travel. Had a bout of bad performance and economy and found the filter gunked up so replaced that and now heaps better. This got him thinking about getting better airflow into it.

He's thinking of putting on a snorkel, how much benefit have people found from putting on a snorkel (he does no water work so no need for the height) and do you/should you also mate them with an after-market filter (eg K&N)?

Cheers
Colin

A snorkel will pay for itself pretty quicly if doing lots of dirt road driving and offroading. Performance gain is negligible if at all.

How so ? I have done about 8000k since I put a new filter in and alot of that has been off road- dirt when i pulled it out for a tap out it certainly looked clean enough and acouple of taps and most of the dust gone. Maybe they may be of more benifit on busy dirt roads or when travelling in convoy. I am planning to get one one day but am a bit concerned on ripping it off in scrub - the last place I worked actually removed them before they got ripped off (cant get 79s without them anymore)

The Snorkel would help with dust but the power advantage is hardly noticable. You must still change the filter as regular. I blow mine out after each dusty trip.
At this stage K&N do not make a filter for the GU.TD.
As the filter is easy to get at regular cleaning is a breeze excuse the pun.

Colin, Yes a snorkel is an advantage particularly in dusty conditions cleaner air is a benifit to any motor. I personally have been everwhere in AUSY from cape york to the bottom of TASSY and tranversed many dirt corragated roads in my travels all with snorkel fitted my filter kept much cleaner so I would not hesitate to fit one, I have safari fitted to mine.But if you want real performance then look at the advertising on the foram page mate it WORKS and is guarenteed.Hows this guys and I did not mention a name and that should keep some knockers happy?

Regards BILL ps I run a 80srs L/C t/d

BTW Bill, if you travelled ALL of those roads with a Snorkel fitted for ALL of them - how would you know if it kept your filter cleaner than WITHOUT a snorkel?

hey...this throwing in a word in capitals is pretty cool :-)

colski,

As the boys have stated bugger all difference in performance when fitting a snorkel, but slightly cleaner air flow, tell your old man to get a price on a 3 inch exhaust, helps them breath heaps easier.

Yep, 3" would be nice. Like all things, have to weigh up cost vs add-ons and achievable benefit.

A snorkel because it is up higher gets cooler air and is supposed to assist performance - that's the theory anyway.

I have a 4.2TD GU and I purchased a K & N filter for it. Two reasons. 1. Better performance due to improved air flow. 2. Huge saving in the long run by cleaning rather than replacing the air filter.

The two work well together. On dirt roads I have an air sock which I put in the snorkel. This helps the filter. (K & N do not recommend their filters for off-road). On the black stuff I take the air sock out or my performance suffers.

It was the same cost to install a snorkel as it was to replace the airflow sensor after it broke. Can never be sure of reason of course, but when the sensor was taken out, it was dirty as one thing. So, I looked on the snorkel as insurance for the next time.
