Single snorkel air cleaner? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

muddpile · 03-19-2005, 01:48 AM

I was thinking about keeping my single snorkel air cleaner and just adding a K+N filter to it and a chrome top. My truck has a stock 82 suburban engine with ram horns and dual exhaust, and will get an edelbrock intake. I kinda like the look of the stock air cleaner assembly, but was just wondering if it restricts airflow a lot, and if I'd be better off buying an open element style. The truck will end up being a year round daily driver, so I figure the stocker should be fine, but am just looking for a second opinion. Thanks!

yea they are definately restrictive. you have what a 3x2 oval opening compared to 14 inches by 4 circular definately more air allowed in with an open element setup

i could tell the difference when i switched to an open element ... but now i hear alot more carb noise ...

If you want to keep the stock look you could add a snorkel like this. I added the one on the left in the pic. I drilled the donor snorkel's spot welds then welded in the four holes to make them look original (I don't have a spot welder). I T'd the valves together so they are both operational. I have a K&N air filter also. I'm sure it's not as much flow as an open element, but it's twice as much as stock- that's how I look at it, anyway.

One trick is to get an electricans punch or a hole saw and put 5 or 6 large holes on the back side where you can't see them....looks stock with a lot more airflow

The K&N lets too much dirt into the engine..one of the worst in the tests I read. (who had that link...I need to keep that one)

You could run the dual snorkels and get creative and run hoses to the snorkels to maybe under the bumper for fresh air, like W-30 Oldsmobiles used to do in the 60's

One air cleaner mod that we do around here is just hacksaw the snorkel off of the housing, it lets a lot more air flow through. Especially if you angle the open end towards the fan. That's what we call a redneck turbo.

Trying to gather parts to do this application to my 78, with the hoses going throught the radiator support to draw cool air in....

I never thought of that dual snorkel mod billogna, but it does look good and stock too. I've been trying to track down a stock dual snorkel air cleaner, but they are mostly off SS cars and are worth a small fortune. This looks like a much better/cheaper alternative. Also, I've read quite a bit about K+N's not filtering worth a damn, so what does everyone run for an air cleaner, just the paper element?

Longhorn Man · 03-21-2005, 07:09 AM

I normally run napa air filters, and a foam pre filter in the dusty months.

Blue Beard · 03-21-2005, 08:14 AM

I've used K&N filters on my cycles for years with good luck.

Alot of racers use them, so it makes you wonder what they do differently.

Billogna, I wish you posted more. Your truck is one of my favorites. The wheels and stance can't be beat.

As far as K&N's, I'm a diesel truck guy and Cummins specifically states that K&N filters are not to be used as they do not filter small enough particulates. That's good enough for me.
