I got my dual snorkel air cleaner today and I relized this thing flows like crap!

First of all its drop base, so that means you have to use that spacer ring around the TBI wich restrickes air flow.

Second, there is a flap inside the snorkels that also restricks air flow. Why is this thing there?

Becuase of this poor air flow I am thinking about either selling it, or modding it.

If I mod it, I will convert it to flat base, gut out the flaps, and get a different lid so I can use a bigger air filter.

What do you guys think about this? Has anyone done this mod? Or should I just sell it and keep the open element?

I would keep it and modify it a bit. You can cut that flap out. That is for the thermac device but I am sure you have gotten rid of it if you have an open element. I have never seen the assembly up close so I cannot compair it. It is hard to beat the ol' non drop base open element. Personally, I would only use the dual snorkel for looks.

If you already have a K&N open element and K&N lid I wouldn't switch over to dual snorkel. You aren't going to gain anything and you probably dropped a few bucks on that K&N setup.

Possibly, I've heard dual can possibly give more hp than Open due to the colder denser air. But havent seen any dyno runs proving this. I heard cowl induction set up on the birds is the best way to go.

My theory is that a lot of hot air is better than a little cold air.

johnjm22

Did you see the pics I posted of it?

But If I converted it to flat base, used a different lid w/ a bigger element, and gutted the flaps, Do you still think an open element would be better?

Yea I saw the pics but I still would need to see it in person. I think a modified dual snorkel can perform better than an open element. However, I do not have any proof of this and cannot be certain. If you modify in the way you described than it should work great.

johnjm22

Damn, I wish I could take my car to the dragstrip and do a dual snorkel vs. open element test. It would finally settle this dispute!

Well I like the idea of the modified dual snorkel but for $20 it is hard to pass up the open element. I bet the difference between the two does not justify the cost.

I have one of those TBI gold rings on my carburetor to raise my triangle non-drop air cleaner into the scoop on my hood. I have ran at the track with and without it and it made no difference. I know a carb looks different from a TBI, but I don't think that TBI engines rev high enough or flow enough air to be affected by this little of a change.

johnjm22

I get what your saying, but I'm going to take every little advantage I can.

Try talkin to "azvolfan" hes got the complete Dual snorkel on his Camaro. looks real sharp.

azvolfan

johnjm22,

Here is my set up. It's plated in black chrome. I'm quite happy with it.

ThraxXx

I love that chrome look.

Z28GEN3

Me too it grows on ya Id still like to see the black chrome someday never actually seen it b4 the pic just doesnt do it fer me.

johnjm22

Looks good.

I'm curious why did you choose dual snorkel over open element? And have you done any modifactions to get it to fit?

azvolfan

I like the look of the dual snorkel. When I decided to change to it I knew right away that I would chrome it.

No modifications needed. It fits right over the throttle body.

FastElectrics

Mine is still black.. I removed the flame arrestor from mine, cleaned it all up, drilled and mounted the sensor that goes in it.. I noticed a slight improvement over the stock single snorkel.. it sounds better also.. when you compair the two, the dual has way more volume in just the one side.. then you double it.. equals more cold air into the engine.. I like it. I kept the functional thermacs. and the original TBI lid.. the one that actually went with it didn't fit.

johnjm22

Nothing gets in the way of the snorkels? I noticed in the pic it looks like you removed the coolant overflow tank.

You never thought about converting it to a flat base so you don't have to use that spacer ring that obstrucks air flow?

Why did you leave your thermac device intact? Thats also hurts air flow.

azvolfan

The overflow tank is not removed. It is on the other side. I guess that is one mod I had to do. I no longer have a washer tank. I also took off the diverter valve. It is kinda in the way but it will work with it on.

I left the spacer ring on because I think it may hit the distributer if I take it off.

As far as the thermac, I didn't care about it. Even with the thermac it flows better than the single snorkel and probably more than a 450 cfm or so TBI can handle.

johnjm22

Would anyone by chance know where to get that 5.0 H.O. Decal?

CamaRod

where di you get the passengers side intake thing

azvolfan

My 5.0 decal was already on the assembly.

As far as the plastic scoops and hoses, I got them all but the local Chevy dealer except the drivers side scoop. The stopped making it and I believe the have since stopped making all of them. So I picked it up on the internet. They are on e-bay every now and then. Expect to pay dearly for it. I bid $182.50 for one and got out bid.

johnjm22

A plastic scoop went for $180???????

I don't think people realize this, but you can buy the hoses and scoops brand new from year one. The hoses are like $20 and the scoops are like $12.

Z28GEN3

yearone doesnt have them, i posted that awhile ago thinkin they did.

I contacted an aftermarket company that makes dual snorkel cleaners and asked them how much they were selling the LH and RH snorkels for and they said $80-90 each. on OEM parts, they supposedly had a large supply of Snorkels but they werent gonna let em go cheap. yea you can buy the regular snorkels real cheap but they arent the same part # as the ones for the L69 H.O. cleaners those snorkels (like azvolfan) has have a larger opening, and the ducts are larger as well.

Teal91rs

and what company is this?

johnjm22

Wrong. Yearone does have them. Here are the part numbers:

Drivers side fresh air hose: AC9LH $18.95
Passengers side fresh air hose: AC9RH $18.95
Driver side air cleaner duct: AC8LH $11.95
Passengers side air cleaner duct: AC8RH $11.95
Air Cleaner wing nut: AC849 $2.95
Air Cleaner Duct Screw: AC855 $1.95
Fresh Air Elbow: 3404N $10.95

Straight from Yearone's Catalog:
The L69 305 H.O. engine option in 83-87 camaros and firebirds made use of an effective dual snorkel air cleaner and cold air assembly. We offer this equipment seperatley for owners of L69 cars who may be missing certain peices, and also as an effective retrofit kit for owners of LG4 305 4bbl cars and Lo3 TBI cars.

Z28GEN3

I know this. the catalog is not upto date, if it was everyone in their brother would have these parts. you must have the same catalog i have that lists them.

if you goto their website yearone you will see they no longer have them. the only ducts they have are the replacement ducts for the stock replacement cleaner.

RAMAIRBOX this is the aftermarket company, since it was about 6 months ago when i contacted them i doubt if they have the OEM ducts. looks can deceive. "Part # 14070917LH / 14070918RH Intake size 4" oval Exhaust size 4" flat Length 14" Material Plastic" at bottom of page.

I got the last 2 right side scoops that RAMAIRBOX had

in conjunction with my dual snorkel air cleaner I use: 84 El Camino K&N filter (taller) and the cleaner lid from a '79 corvette.

For spares:
I also have the dual snorkel cleaner from said vette and a right side scoop for the system, also a modified left side scoop from the LO3.

azvolfan

I also check with YearOne when I was doing the dual snorkel install, and they did NOT have them. Even though they said they did.

3rdgenstm

If you want to sell it, let me know. I have been looking for one for a long time.

82Z28NAZ

I'd sell it... but you wouldn't like my price

3rdgenstm

Awwww....

Come on....

Pleeease...

johnjm22

My bad Yearone doesn't have the scoops. But they do have the hoses.
