There's really only two ways to make a filter flow more air. One is to make the filter area bigger, so that the air has more surface area to go thru, and the second is to make the filter not filter as well, so that air can get through it easier. That's what K&N does, they make a filter that doesn't filter very well, and flows more air. You really want as much air as possible? Don't run any air filter at all. I believe that's what the NASCAR guys do, but their engine only has to last 500 miles.

Actually, K&N makes a filter that CAN flow more air. But, whether it does [or not] is really a function of how much air your engine actually NEEDS. If you have a stock C3 engine, it really doesn't need more air than what the stock air cleaner/filter can provide.
But, if it looks
to YOU, and you have the extra ca$h to throw down the toilet....what the heck....

Contrary to the above opinions I think K&N air filters are a good idea even if they do nothing in the way of added horsepower. I'm talking about the filter element only.
No need to clog up landfills with dirty paper filters when I can just as well wash the dirt out of my K&N's and re-oil...said to last 1 million miles.

But, if it looks
to YOU, and you have the extra ca$h to throw down the toilet....what the heck....Maybe it has something to do with straightening out the airflow or something like that? Anyway, we all have our prejudices, and one of mine is, a new filter is better than a cleaned-up old filter. This is America, and we all have the right to have our own opinion. (for now, anyway........cue dramatic background music.) As my Grandpappy used to say, before he came to the clearing at the end of the path, "It'd be a boring world if we all liked the same things."

Dynoed my 78 L-82 4 speed last October 2011 with Mcjacks shorty headers, 2.5 inch duals, and Monza Turbo mufflers with a K&N air cleaner in the stock OEM dual snorkel air housing and the engine produced 233 RWHP with no air cleaner and 232 RWHP with the K&N in the stock air cleaner housing!

The K&N filter will flow more air than the "stock" air cleaner/filter system....because the filter doesn't filter as well as the stock system. It just is 'purtier' 
and has bigger "holes" for the air.
[Kinda defeats the purpose of the "air filter", doesn't it?]
P.S. People wanting...and buying...K&N filters, and the extraneous hardware that goes with them, is a perfect example of U.S. "marketing" at its best (or worst, depending on your point of view). Actually, the pinnacle of marketing work was done by GM by convincing the general public that it actually wanted to buy pick-em-up trucks for their primary vehicle--at a price of over $40K!!!
Prior to that 'sales pitch', they couldn't get more than about $2500 for any pickup truck they sold. Go figure... P.T. Barnum was right.

thew exhaust is a good upgrade if u live in a state were u can remove the cats even better as far as the filter no gain there the 3-5 hp it might gain on a engine dyno you would never fill the k and n is nice that its cleanable it is a good investment expecally on a open element breather might try setting timing about 2 degrees advance if your looking for a little bit of performace for cheap and adjusting the tension on the secondarys on the carb not to much to gain but some and its free

A 4" open-element air cleaner with just about any filter will provide all the air an engine needs. Drop base or otherwise blocked stock air cleaners and/or short filters will easily steal HP...the amount depending on the restriction of the design. I'm always surprised when I see an engine wearing a tall intake topped by a 2" filter.
I buy K&N because I only buy it once and clean/oil it once per year. I disagree from testing I've seen that it's less effective at filtration, but certainly it needs maintenence.
Run a 4" open-element cleaner (or as tall as you can) with a good filter and change/maintain it regularly - all it takes

I'm sure ol' P.T. must have been correct about somethings, but if you're referring to the 'a sucker is born every minute' quote, you'd be wrong.
