DIY snorkel ????

Ok So if you guys cant tell from my past threads and comments I am a DIY guy all the way threw.

SO I have been thinking about getting/building my own snorkel.

It started by looking at them then once I seen the prices and material they use I thought yeah right time to DIY this thing.

I am going to go into the original air inlet and just shave down a 2" pvc pipe to fit then glue it in then just run the rest of the 2" out to the top of the truck.

Now down to the questions I have on my layout I came to make

Does anybody know if I will run into an issue using only 2" o.d. pvc?

I was thinking this may give me air restriction after all the length I had to use. Total length of intube air travel will be 5'. I did not install any air cleaner at the end because it just goes to the original air box anyway. It was all primed and glues then rubber sealed after. Not that i am gonna take it in deep water at all. Any info will help alot. Thank you in adavance

2" will not be enough. It needs to be 3.5-4" to provide enough volume of air I think. do a search in the YJ forum for DIY Snorkel, you'll get plenty of hits.

This may give you some ideas.







I have an ARB safari snorkel but I had to make up the under hood section. From what Ive read, 2" would be way too small. Even at 3" with the tight turns isnt really enough. I think it was something like for every 90* turn it cuts down airflow around 50%. While I didnt notice an increase or decrease in power/mpg or anything, I plan to cut into the side of my airbox to eliminate the 2 90*s I have going into it

Yeah I was thinking that the amont of bends I have would not work and the small pipe there either. But it was worth a shot regardless. the only problem Is I cant do 3" or any larger Pvc Or it looks retarted and the holes are way to big and the pipe is way to big to route out the truck unlees I do alot of relocating and fabing.

All other snorkel kits all have soft bends and they reduce down to a 2" at many points. But like I said if it will work and not cause huge problems I should be fine right? Should I just hook it up and run it to see? Or will I not be able to feel or hear a difference till its to late?

The smallest part in my intake is 3"s, the ARB snorkel itself is a lot bigger. I think like 4.5" at the top

Its best to keep a consistent size with as least amount of bends as possible.

I had to relocate the windshield washer fluid bottle, the horn and the airbox itself. In order to fit the 3" tubing infront of the box I had to move the box back and up a few inches, if you notice, it almost touches the grill support

I can also tell that you had to change you mounts for your wiring as well. The ****ty part is I already cut the hood. Which I dont really care about but it does now lock me into going out that way. I had to relocate the horn but I was trying to keep the fluids in the same spot but I guess now im into this and need to redo the entire thing in 3". I was reading some other posts and threads like you said and it seems that everybody is having problems and needed to upgrade the size of the tube. They also talk about the bends and restirctions as well to the air flow. I think I am gonna redo it in 3"as much as I can But leave it short and just above the hood or right below the windshield.

I was also thinking of just cutting out the old airbox and redoing the sensors into the nex snorkel do you think that will give me less turns and a better approach fro airflow and to be able to get that pipe out the corner of the hood?

Yeah the wiring is for the windshield washer pump, didnt have any loom to cover it at the time of the pic. Yeah, theres a few good write ups, one using a really cool custom filter setup. If you could do something like that and eliminate all the bends youd be all set.

Heres the filter I was talking about

If you read through the link, I think he suggests switching to a 3" coupler

Yeah I think I am gonna make my own Hbrid of those though. And that is good to know that the wiring right there is only for the windshield wipers and all. So that shouldnt be a problem to move outta the wa right. Or was that a peach?

I feel if I can move those wires and with the horn already moved I should be able to sneak in the 3" to the Flex pipe that goes to the old box. And then just come up with my own filter set up from there

This build looks awesome and very effective but it leaves me wondering why he then went to the 2" after all of that or did he bump up to a 3 or larger after ?

It was just a matter of splicing in some longer wire and tube for the pump. That was the easiest part. I think he ended up switching to 3"

So check this out man I started to get he parts together. It was $20 for the flex hose needed 2. Each of those reducers are $25 needed 2. The slip reducer $10 again need 2. Then the filter $20 and the seals and glue $15. So already I am way over this kids guessed prices. But im into it this far. All the holes I cut will still work. I didnt have to move the fluid tanks or the wires!! It will not be rock solid but it will be done and good enough for what I will need for now. I will post up pics soon.
