Is there any appreciable performance gains to be had from fitting a snorkel to a turbo diesel....STR 3 litre Narvara

Hi Marklynn,

I purchased my 3.0TD Navara STR with out a snorkel, clocked up about 8,000kms, then installed a Safari Snorkel.

Cant say there is any real improvement in performance, mainly peace of mind when driving through water. Also reduces dust intake on dirt roads when behind other cars.

Hope this helps.

Hi Tony..How does it make you car draw in less dust following traffic on dirt roads????

When cars kick up dust it starts at the ground and makes a wall about 20feet high... How does the snorkel help that???????

I would think that the dust cloud might be a bit thinner with smaller particles at 5 or 6ft off the ground than down at guard level.

Just a thought.

On some vehicles, depending on design you may get more dust kicking up in the standard intake area. If you're really desperate you can swivel the air ram around so its backwards and not 'forcing' or 'ramming' dust into the motor. This is also good for competition when hitting water at high speed preventing water from travelling up the windscreen and into the snorkel.

A snorkle is an Engine Saving Device , pure and simple. Helps prevent getting a belly full of water , and allows the engine to suck in cleaner cooler air.

The performance issue with Snorkles is arguable.

Some say they do get a benefit from it , but some get slightly worse.

I would suggest if you intend fitting one , then do it cause you wont to make sure your motor lasts , not cause you are looking for performance gains.

....and take heed of posts herein re the noise that a lot of installations end up making ...they can rattle....and drum etc.....some resonate engine noise up into the body shell.....but hey ........what idea in this world is perfect ? ....its all compromise !

I put a snorkel onto my gu111 patrol and would say nothing has changed except a small amount of wind noise.Besides that it is peace of mind
Cheers Tim

A friend fitted one to my 95 TD42 Patrol
I commented to my bride on the way home that I thought there was more grunt there and I still think there is!
There's a hill near our house that we used to struggle up in second and can now get 2/3's up in third..... (I kid you not!)

...... and I also meant to say I hadn't heard of the noise issue before... I certainly haven't noticed any increase in noise, but it is a diesel and I do have muddies on... :-)

Sorry.... also meant to say that really, I only put the snorkel on so I could do water crossings more safely.... the noise/power issues are things that are an aside to the original idea of having one.

The only effect a snorkel can have on performance is negative as it is nothing more then a long extension tube attached to the air intake, thus providing added restriction to air flow. Only benefit is in very deep water crossings.

Well Mick.... opinion is divided on this subject as much as tyres and fridges... and my opinion is just that... my opinion. What works for me doesn't always work for others, but my truck's "grunt" went up with our snorkel!!! I promise!!

Have fitted them to t/d rodeos (previous model) and found a big difference in power and spool-up speed, BUT this was to do with the snorkel removing the restricted factory airbox inlet pipe. You can get a 'ram air' effect at high speed if you have a forward facing 'scoop' on top. As for less dust etc, well i'll leave that up to judge judy.. They also aren't worth jack for water crossings if the installer didn't use liberal amounts of silicone to seal all the joins..
