I had to look it over several times, very nice but I do have a few questions. What’s the wind noise like in normal driving? If your in a heavy rain does the rain just go right in that intake or is there like a route for the water to escape or keep it out? Do you find it acts somewhat like a ram air intake or does the air filter kinda reduce that effect? If they made one longer on front reach it would fit second gen better seeing air intake so much further forward but yea, comments about moving fuse box would be a royal pain. Too me as is would almost seem easier to relocate abs brake box considering less involved to move. Did you use like silicone sealer when you put bolts into pillar or rubber washers to seal out rain and keep rattles and squeaks down? I know, too many questions but very curious. After years of driving semi I found the fancy Petercars and KW may look very cool but sucked for noise with the intakes by mirrors and the stacks near doors, gave me headaches after hours of driving and you never really wanted the windows down.

As far as wind noise, I never noticed a difference. My truck rattles and squeaks so much anyways, and then throw the noise of 33" boggers on top, and it's not a quiet ride by any means. I was kinda hoping for a cool high vacuum air being sucked sound, but I couldn't tell any difference on my truck.

Haven't driven in a heavy rain, yet. But where the head attaches to the rest of the snorkel, there's slits that rain is supposed to come out of. According to safari snorkels website, anway, and my Chinese knockoff is built the same way.

No ram air effect that I've noticed. I bet since the snorkel is so long, and so many bends in the ducting, it negates that effect.

I've seen videos on YouTube of various offroad vehicles with snorkels, some go almost to the headlight it seems. Those might be a better option for later second gens.

Have not applied any sealer to the a pillar mounting bolts yet, but only out of laziness and a lack of sealer. I definitely need too.

I did that on my old 91 Toyota 22re engine and honestly never had a problem. The cap on those even has a little breather vent and I just put a vacuum plug on it lol

I just wish our distributors were easier to get to! I'm a chevy guy, but I think Ford had a good idea putting them in the front!



Also, drove the truck in a fairly heavy rainstorm yesterday (not quite a monsoon, but had to put the wipers on high) and didn't seem to have any issues with the snorkel taking in rain water.

How deep of water do you think it can drive through?
In the service snorkel kits for jeeps attached to the tail pipe. The theory was the engine couldn't run if the exhaust pipes were filled with water. So with the kit you could ford a river as long as the water was below the carburetor (approx.)

In reality, engines will run fine with the exhaust underwater, until you shut them off. Then, you run a risk of water backing up into the cylinders.

Hopefully I never get into water higher than my bumpers! Lol. I consider it more of an insurance policy. Seen too many videos of guys going into water they think won't be that deep, next thing you know, they found the hole, and it's over their hood.

The intake is sealed all the way up to the top of the snorkel. I packed grease in all the engine critical electrical plugs, and coated the seams with liquid electrical tape. Still need to run my vents (both diffs, trans, and tcase) up higher, to hopefully keep as much water out of them as possible.

As far as the exhaust, I agree with TomA. I've seen plenty of trucks running just fine with the tailpipe submerged. The exhaust pressure keeps water out.

The only problems, might be if the truck stalls, and the water level is higher than the exhaust valves. Then water can potentially flow into the engine.

Almost looks like on the 98+, you could rotate the windshield fluid tank 90 degrees, and extend through the fender in front of that relay box...just need to find a slightly longer driver side snorkel.

I've seen longer snorkels on offroad YouTube videos. Just have to watch one, figure out the application and give it a try!
