I am rebuilding my 82 with a 350, and it wont have any smog on it. The 305 originally in it had the single air intake, i hate it, i dont like how it looks, and it obviously doesnt provide enough air for a 305 let alone a 350. I am seriously thinking about getting an open element filter by K&N. Has anyone tried this and if so what do they think? I know it takes in hotter air, but does it make a huge difference? Thanks

 

Open elements are definately the way to go. There is plenty of information about open elements in the TBI forum

i like mine...i got the k&N xstream lid to boot....it sounds good...real good.

i didnt know my engine made any noise...but now it sounds pretty aggressive

 

With the addition of a cowl hood, you'll also be able to get a more plentiful amount of "COOL" air in the system also. But that's for later on down the road. Any ways, yes it's a good idea because it will flow more than the single/dual snorkle air cleaner.

My friend is using one on his 85 Z28 LG4. He bought the K&N one from Jegs for like $85 or so. He has been very happy with it, it really sounds sweet when you go to WOT.

I've got a LG4 and went to the dual snorkle setup over the open element. For the amount of air my car needs, an open element isn't necessary, and wouldn't give me as much power as the Dual Snorkle does because it would be picking up hot underhood air.

 

A dual snorkle will give you a cooler(fresh)not hot air as with an open element.

I have people telling me different things on different days. Some say open element & other say snorkel for cooler air. Does anyone have a consensus as to what is best for any particular engine or year model?

Open element is the way to go for most setups. If you have a really tight engine bay like a 4th gen camaro or corvettes then a cold air setup might be a better choice. All in all they come out to being about the same performance. The advantage of an open element is the price and sound. For $20 you can't really go wrong. When I had teh L03 I had the stock unit, the stock unit with all the ultimate TBI mods, a dual snorkel setup, open element, and no filter at all. I have a story to prove that there is a difference between stock snorkel and open element but I'll get to that in a bit. I honestly didn't notice much of an improvement when I did the ultimate TBI mods. The ring removal probably helped a little but I was still sucking air in through a small snorkel. I even had a ram air setup through the high beam but that was the first thing I got rid of because it looked like %^#$. The dual snorkel was great after I gutted it. The car sounded great and there was a noticable increase in power, not a lot but when you race your friends frequently you can see certain things. Maybe it was the floormat now that I think about it....lol . Really though, the open element sounded like the dual snorkel but because my engine wasn't exactly a fire breather, I couldn't feel a difference. Now if you figure the dual setup is ~$60 used now and a new open element is $20, hmmm....
Okay, now I told you before that I had a story about the stock air cleaner and no air cleaner. Well at my summer job we had a glass beed machine for cleaning parts. I took my stock air cleaner and after I gutted it I cleaned it up. I forgot that I needed some high temp paint, so during my lunch break I drove over to the local pep boys. Well while I was pulling out onto RT.1 (like I did every day) my car lost traction bad. This is a 3.08 open so I figured it was just sand or something go spilled. Well it was a hot summer day in the high 90's and the tires are 245/50 16. That was normal. I didn't do anything differently but the car still broke traction and that was when it hit me that I didn't have the air cleaner on. DUH!!! I was only 17 and I thought that a bug would fly in and #%@# my engine up! So from an unbiased position I noticed the hp improvement, it had to be at least 10rwhp improvement. NJ Speeder runs no air cleaner at the track, infact he drives the car with no air cleaner too frequently if you ask me. He also has an L03 bottom end and stock cam running 14.2's with a stock sized TB!!!
Get the open element, if you don't like it sell it for $10, so you're out $10, ladi frecken da!

I say both... if you can get away with it, find the intake from a TPI car in a junkyard and gut it and put it in ... might take a little bit of modifying but probably not much... just leave it gutted, don't use filters in it because you already have the open element...

works better than the snorkel and you have a direct flow of cold air into it, so it not only cools the engine bay down a little it acts as a cheap way to get cool air into the carb /tbi

 

I run an open element and I LOVE the sound of it at WOT
Is it better/worse than a dual snorkle? I don't know, I had plans to make one, but the crome edelbrock air cleaner just looks too damn good to take off

Besides, i might get a cowl hood in which case I will be getting cold air anyway.

 

i did the open element thing a couple weeks ago-man what a difference! the sound is much more authoritive and mean and i would say it was an honest 10 hp gain! yes it flows hot air, but the amount of hot air far outweighs the small amount of cool air the snorkel gives, so yes its worth it. edelbrock PN 1207 14x3
