K&N filter
#2
From what i've been reading the stock air box will flow more than enough air. No real need for a aftermarket CAI on a stock motor. I may change to a K&N filter only just to have the reusability and the option to clean it myself.

Not sure what results you're referring to. I didn't dyno it before and after if that's what you mean.
I put one in mine and it certainly changed the exhaust note to something more growly. I like it. I figured K&N did lots of research and likely were able to get more performance out of theirs vs OEM. That's just a hunch though, no personal experience numbers to back that up.

Although I have the K&N CAI systems in my Corvette and Camaro currently, in the past I have run their air filters in several of my vehicles using the OEM filter boxes. IMO their was no noticeable improvement in performance and only a slight difference in sound. The biggest advantage I found was no longer needing to replace filters and the cleaning kit, which is good for multiple cleanings, only cost a fraction of what replacement filters cost (around $15).

I have an AFE Power Dry Pro S air filter with intake shroud for sale $140 The filter is washable and a dry filter so you don't have to worry about over oiling or gumming up your MAF sensor. If interested send me a PM.

I replaced mine and immediately noticed the exhaust note change out of my cat back Magnaflow. I could also hear the engine sucking air from my drivers seat with the hood down and door open that I hadn't noticed before. The butt dyno felt a little difference, but then again my air filter was manufactured in July of 2007... Not quite 50k miles, but was still in need of replacement! Took awhile for the computer to relearn its fuel tables, but my mpg is up +2-3mpg over each tank. That's with some spirited driving as I dd mine. FWIW, I'd recommend it!

You might want to reconsider using that type of filter. Nothing is for free, and the increase in airflow is at the expense of allowing more abrasives into your engine. See post #32 here: https://corvetteforum.com/forums/c7-...uld-you-2.html
From that post: "In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms. Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt. See the data tables for a complete summary of these comparisons."

If you want maximum power, remove the filter completely. If you want maximum filtration, use a real dirty OEM filter. There is no magic bullet that does both. All filters are a compromise. You get to pick which end of the spectrum suits you best.

Sound is the goal
I am not concerned too much with power. Its sound I am looking for. I have Borla Touring axleback mufflers on the car. They sound good, but not quite deep enough, I am looking for a little more start up rumble.

x2 has nothing to do with exhaust
you want incoming air filtered well, look somewhere else for power.

so for all hand wringing, the K&N filtration is 97% as effective as the OEM (99%)? 2% difference? WOW
Whether there is any performance gain or not, it's reusable for lifetime of the vehicle.
I have them on my motorcycles for practical reasons (try finding these filters when you want one) . I think they make sense for any vehicle that you want to own for a long time.
The chart convinced me I should get a K&N for my C6. Checking the internet the price of an AC and K&N is within $5.

My '12 Tundra has had one for a while with no issues and I just put one on my '13 GS Sunday, haven't driven it yet. FWIW local Chevy dealer wanted to rape me for $185 for the element. I'm thinking I was quoted for more than just the filter element but I asked and was assured that was the price, totally ridiculous. I got the K&N for around $85 I think, seemed to fit well.
