Thread: I can now say cheap snorkels do NOT inhibit air flow

I guess it would be greater if you put a head on with more cross sectional area, but probably not worth it.

I made my own snorkel from metal and have it forward facing (v8) with a ram head. I get way too much debris in there. Leaves and sticks mostly so have planned to reverse it when i get some time.
I will see if there is any notable difference however i expect not.

I'm sans snorkel still but i will install one one day, I just hate the look of the Safari and clones on the D2.
Strangy assured me it'll double/triple the life of the air cleaner.

My thoughts are a 4" stainless pipe bent/fabricated up (and powder coated satin black) straight down the pillar and into the guard, and just fabricate a nice big plenum inside the guard.
I really don't like the look of that duct running along the guard.
It'd be rearward facing, just like all the Japanese utes running around here have.
It's really low on my list of priorities though.

Yes I know, i know, a bloke that had a Deefer for sixteen years talking of aesthetics.....

Yea its what i did. Just ran it behind the guard. Only just fit too i have to say.

But i find it pleasing to the eye where the outer guard ones look horrible...... (personal choice obviously)

Im not sure 4 inch would fit. I think mine is 3 or 3.5 and only just fit.

I haven't even measured it up yet, too many other things to do and real work keeps intruding but I'd fabricate a box or oval plenum inside the guard, the pipe down the pillar would just feed it.

Ok,, I'll ask....

Why the Plenum?

and Damink? would oval pipe be any easier?

so running with a reverse head,,
no turbulance/low pressure concerns?

I suppose a lack of air is what I'm concerned about...

Im not entirely sure it would actually as there is a rib behind the guard which limits positioning of the pipe.
My guard is pushing up hard against the pipe behind it.

I might rip off my guard today and take a pic of how i ended up directing it.

By memory i had to make a few different bends to get it to fit nicely.

Here is a pic. Damn i collected a bit of mud there hahha.

I only peeled the guard back to show it but you can see the mud covered pipe above the rib. That rib was a bit of a pain.

Sorry for poor pic. Car filthy and have other work to do so could not be bothered taking guard off completely and cleaning it.

Also i ran to the front and into the airbox via the normal opening because i have a gas converter fitted behind the airbox or i would have gone in through the inner guard a lot earlier.
