homemade dual snorkel
i'd swear i saw a post here about making a cheap dual snorkel setup, but i can't find it. i'm probably searching with the wrong words. anybody have a link to it, or an easy way to do it?

I think I know what you are talking about. Was it the modified stock unit with just another hole cut out for another duct to go towards the passenger side? I will see if I can dig it up.

IMHO......I run mine with only one hose. I have found these engines to not need that much air.

The stock setup is like trying to feed an engine with a straw!

I hope no one took me wrong...I meant only one 4" or larger intake hose and snorkal...not the stock pos good for only a four cyl.
The open element is about the cheapest mod one can do and it flows more than about anything else for the price. It's mostly a personal choice.

I went with the L69 set up. The breather assembly I got from Dave Staubli. I got lucky. I got most of the parts at the local Chevy dealer just before they discontinued them. That drivers side plastic duct was the only thing I did not get. I have gotten one since but the are like gold.
I also had it dipped in black chrome.

I thought you meant the stock straw going to the intake. Yeah, I bet 4" ducting might do a wee bit of good!

There is a company that makes nice looking fiberglass units with dual snorkels, You can buy 4" hoses for $15, and inlet pipes as well.

They have everything you need for a professional dual snorkel set up from air cleaners to complete kits. No to mention you can get them in flat, and drop base for a taller filter. I think they look good, but havent got one yet. Im still use the ultra lame flipped lid and a K&N cant be to bad though my car is making some decient times.
