Changed to K&N filter ?
Has anybody changed their stock air filter to the K&N filter. I am talking about just the filter not the entire housing. Playing around in the garage today while it's snowing and took off the intake to see what it was like. I've read the posts on stock vs. aftermarket intakes and after seeing the stock '10 intake it looks pretty smooth and unobstructed but the stock filter looks pretty tight. I put a really bright LED light at the end of the stock filter and nothing got thru to the other side, so this got me wondering. K&N makes a stock replacement filter #0782 for my '10 LS3, is there anything to be gained by changing? Motor will be stock except for catback exhaust for a while, it's only 2 weeks old.

I'm going to add a K&N in the spring with a vette air...I think that will help force air into the intake and I think that will allow the K&N to do better....I don't know for a fact but I think its a good idea lol.

I have always used K&N filters in my vehicles including my Vette. I have not been willing to spring for the cost of a cold air intake so far! The K&N filters alone might not add horsepower as claimed, but, they do breathe easier....in my opinion. Others will disagree!
It's also an economical filter when you consider the cost over the long term. I keep my factory filters in the garage, just in case I want to drive while my K&N filters are drying during the cleaning process.

Can't comment on K&N in a Vette, but will tell a K&N story from a previous vehicle.
I drove a '93 Jimmy many years ago. When I moved to Colorado, I was unable to burn the tires at all. A few weeks after moving there, I put a K&N filter in and was able to spin the tires freely. There was clearly a significant increase in power over the Fram filter that fit a '93 Jimmy. I've run K&N in every vehicle since with pleasing results.

These "high flow" filters are for people that don't understand filtration. The stock filter is the best filter you can buy for your engines health. The performance gain for the filtration lost is almost nonexistent.

More air flow=less filtration.

I would just open up my shroud and get some cold air to your current filter. Would only cost a few dollars.

I would buy it.....I always installed K& N filters to my cars.....it's not a big difference but, I enjoy the added manifold noise when I step on it. It depends if $85.00 is a lot of money to you? One advantage is that you never have to buy another filter....just blow it it off or hose it off and apply the spray oil to it and your good to go another 6 months.

Save your money, if you want more noise from the air cleaner assembly, get a LS7 assembly from corvette recyclers or remove and plug your silencer. The factory air filter is just fine, and it is not like the regular $15 filters of old, so you really can not use the analogy of what you did on older vehicles.
With that said, it is your car and you can do whatever you want. If you do go that route be very careful on how you oil it.

When you shined your LED light into the opening of the filter, it hits the closed opposite end of the tubes. If the light beam could follow the path that the air takes, then the light would have passed through the filter. Because of the depth of the filter, the actual filtering area is much greater then the surface area. That's why the Donaldson filter last for 50,000 miles. It also filters better because it is not constructed of plain old paper. It is constructed of a nano synthetic media that filters better then a paper filter, and way better then a oiled cotton gauze filter.
