Dante’s Peak made me also want a snorkel as a kid. I’m now on my second. I’m running the ARB with a
Sy-Klone Precleaner. Love it but definitely reduced power.

Looks like the same exact model, lol

Breather mods? Would you elaborate please?

It is for your differentials so that they don’t suck in water in a 1 in 500 chance you cold soak them.

I think I'm about to order this. Just had a little scare with some water and this is the cleanest looking snorkel out there IMO. I really like how you wrapped it. Never thought of that..

Cool! Thanks the detailed install information.

I have a supercharger on my TDR. Will the Alpha snorkel work with that set up?

I hate to use a plot lifted off the internet vs one of my in-house CFD runs from major automotive manufactures or from our racing teams data sets, but much of our internal data is proprietary and not legally sharable.

For concept, here is a CFD (Computational Fluid Dynamics) run of a Land Rover, which is similarly not the most aerodynamically inclined vehicle, like a Tacoma. Blue contour regions depict low pressure zones and red in the streamlines depict high velocity. Any competent CFD engineer would tell you the absolute worst place possible for an air intake is in a high velocity low pressure zone, like you couldn't pick a worse place according to science than the trailing edge of an A-pillar. Note how flipping the intake side to face the windshield would provide a significant increase in pressure, and would be further increased by the 'wall' created by the snorkel intake rise on the A-pillar. It does look sleek and will work fine for most, but from the engineering perspective it is a poor design for those interested in maximum performance, which obviously may not be the main audience of a snorkel. You can certainly flip a snorkel head backward and it will still work fine, but performance will be reduced, there is a reason they are mounted forward facing. Personally I will not run any products which are fundamentally designed wrong out of principal, because it really bugs me as I look at it and think WTF. But I know most are not so engineering OCD and will be happy with a low profile option.

This is not true. You need to consider the stagnation pressure. The freestream flow has relatively low pressure high velocity and would be the most desirable place for a snorkel air wise. I doubt the viscous losses of flow approaching a snorkel over the vehicle are greater than of the snorkel internal diameter.
