K&N air intake system for my '14 Z51
To those that have installed this was it worth it? How easy was the install? Do you recommend it? Pros and cons?
K&N claims 12.5 HP and 16 foot/pound increase????
Thanks!!

The K&N 63-3081 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Chevrolet Corvette models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-3081 air intake comes with an ultra-lightweight carbon fiber K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. The oversized oval cone-shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points requiring commonly available tools to do the job.
•Guaranteed horsepower gain
•Designed to improve throttle response and engine sound
•Free-flowing polyethylene intake tube
•Replaces entire factory air intake system
•Easy to install, usually in 90 minutes or less

We would clean our filters every week, especially when racing in the dirt, too. Know how inexpensive and easy it is to clean a K&N versus putting a new paper filter in every week?
PS: Don't you think GM, might just like selling you a new paper filter every 10kish miles or so?

How about every 35,000 miles and the benefit is that you actually get clean air into the engine. The stock air filter is state of the art for cleaning efficiency and low pressure drop. These high flow air filters are just advertising hype.

Well...
The average dyno error rate is 1 to 3 percent.
If you use those numbers, you can easily get
those numbers +/-. I would never confirm or
dispute those numbers based on that alone.
What I can tell you is that we have sold a ton of
these intakes since they came out. Our customers
report better throttle response and better HWY mileage.

Yet gains are still had by installing aftermarket intakes or simply replacing the air filter with an aftermarket drop-in Don't give the stock filter too much credit, although good in design and better than its predecessors of years past, it's still a restrictive paper element that costs just as much to replace as a reusable aftermarket option. If you want a good balance between flow and filtering, the AFE ProDryS is an excellent choice.

New filters are about $100. Just the K&M Filter with no intake modification is around $70. Only need to put ONE K&M filter for as long as you own your C7 and cleaning a K&M Filter is probably about $1.
I'm not affiliated with K&M. Just speaking from experience.

OK 35K miles. Just don't get into much dust or heaven forbid a dirt race course.

For a truly minimal gain (read K&N's advertising carefully, they always say gains "up to" some HP and torque number) which someone else has already observed is within the error of a dyno.
If you want to let more dust into your engine that's your decision. I won't. This says all I need to know:
This graph is from an excellent analysis entitled "Debunking the K&N Myth - Why OEM is Better" at this link: http://www.nicoclub.com/archives/kn-vs-oem-filter.html It's a very interesting read.

K&N showed on a video around the same gain with just a K&N OEM replacement air filter. K&N does not say the complete system well not void your warranty as they do for just the filter replacement. In the past I asked at the service department at a Chevy dealership if a replacement CAI would void my warranty and was told they would not. On my C6 LS3 tried on the 1/4 mile the stock system, the Z06 stock system with a K&N and the K&N CAI, all the runs where within a 1/2 tenth and 1/2 mph. The LT1 system does look better then the OEM system under your hood but what really helps is air temp and engine temp and that is free.

when someone can prove to me without a shadow of a doubt that these "mods" produce significant gains in bhp then I will fork over my hard earned money, I fell for the Diablo Tune, I will not fall for a CAI without documented proof and not some graph that any grade school kid could produce with MS Paint. Fool me once.......

What do you mean you fell for the Diablo Tune?
I am thinking of getting the Diablo tune. Is it not worth it? Do you know something I don't know?

I disagree. I use to race motorcycles. I'd race against my friends with exactly the same bike. One difference. They had K&N, I didn't. No dynos, real life, elbow to elbow racing. I was embarrassed, they'd beat me so badly. Once my scoots were broken in, the first thing I'd do is put a K&N in. Made all the difference in the world, the embarrassment came to an abrupt halt, once my new filter was in.

.How can replacing the stock intake, which isnt flow limited at part throttle, result in better throttle response / gas mileage?
Changing the floor mats should make a comparable difference....And would have less warranty ramifications.....

I also bought a Diablo for my 2015 Z51 auto, but won't consider trying it out until winter 2015. I want to see what my car will do bone stock before modding it.
**************************************** **
Now to the cold air intakes. I've been seeing this >10 hp gain on different cars since I had my 2005 auto GTO, and I've yet to believe all of this hp improvements. Of course dumb me bought one for my GTO, G8 GXP, and 2 2013 Mustang GTs.
The thing about the cai is that we want so hard to justify paying >$350 bucks we can feel the immediate improvement by the seat of our pants, and our ears hear something different. The cai is something any of us can install within an hour at the house with minimal tools, it's something that we believe we can get immediate results for minimal dollars. On a great majority of cars, this is the first mod that is done. All of us want to so hard to believe what we see written.
Also, I don't want to see any video about the cai from the producers of it or those who sell it.
My opinion for what it's worth...........75% snake oil and I'm going to be very generous and claim 25% truth as far as horsepower improvements go, as advertised.
I can believe up to 3 or so hp, but not anything over that.
Lastly, the wording of up to 15 horsepower is like saying a slot machine pays up to 99%. Vegas is still being built and improved mainly on slot winnings. Up to 99% can also mean 1%.

k&N is the automotive air filter equivalent of those XRAY glasses that used to be advertised on the back pages of comic books and Mad magazine.
Just take your stock filter and punch a few holes in it with a pencil and you'll get the same result...
