not this again,
total junk.
So you think the engineers at k&N are much smarter than the Corvette engineers.
My gosh, save your money, this is not 1975.
Read what the engineer that worked on the Zr-1 filter said, you will only get more dirt and oil on the sensors.
total junk.

15 hp
They advertise a 15hp improvement. First, who could tell if they had an additional 15hp. Second, I agree that the largest car mfg in the world has the ability to engineer a quality air filter.
Pass on the KN air filter and take your daughter to a Katy Perry concert. Or you wife to Taco Bell. They will love you for it.

I disagree. The stock filter is designed for a specific volume of airflo, however thats one end of the pipe that the total engineering for fuel economy, flow, and backpressure.
Its very simple, if you limit the volume of air going in, you limit the total combustion. The first point to limit IS the intake. Do this, open your mouth real wide, and try sucking in air without any filter, and with various densities of fabric. This is the same principal here for aftermarket filters. Paper filters restrict, cotton filters may be less restrictive. As long as the backpressure of the exhaust system can accomodate the additional volume of flow, you have an increase in output.
Frankly, I prefer having a filter that is resuable and I dont have to nanny every 10K miles

Total JUNK, proved over and over again on EVERY performance forum.
Now if your car is from the 70-80's go for it.
I still would not, more flow in a small space means larger dirt particles.
638hp on the ZR1 and the engineers said there would be no improvement with any filter in the space unless you want dirt in.

Corvette filters do not restrict, do your research, these engineers spend huge dollars and research on clean non restrictive filters.

^ imho, this is what I refer to as pure Logibull. An attempt at constructing a logical argument employing bullshot facts. The above logibull is fatality flawed in it's initial assumption. Poster assumes that the factory filter, "designed for a specific volume of airflow," limits the volume of intake air available, to an performance robing rate.
To achieve credibility, please demonstrate to us the required airflow for the C7 engine to achieve it's maximum performance peak horse power and torgue - and then demonstrate to us that the factory air filter will not flow at that rate.
I'll bet a nickle, that the engineers tasked with developing the new 2014 "LT-1" 6.2L V-8 VVT DI engine, and equipped with a multimillon dollar development budget, partnered with suppliers capable of providing a filter with no performance inhibiting characteristics. In fact there have been separate articles published specifically detailing said filter development.
But it's much easier to foist Logibull on folks than do actual research.

There is a reason K&N states clearly on their webpage that their OE replacement filters generally increase horsepower from 1 to 4HP.
They start throwing out those claims again, and the FTC will make them back them up. The FTC does not allow a company to use testimonials as evidence of performance.

That's a joke. K&N is very careful not to make 15-20 horsepower claims when they know they have to back them up. Who made the 15-20 horsepower claim? K&N or Motor Trend?

Complete lies, why don't they show the graph if it is true.
