Same here. I put one in my maxima for the simple fact that I don't have to keep buying one. Eventually, I'll put one in the Sorento when it is time to change. AND I've never had a problem with it, some say it is bad for your vehicle but the maxima is at 210k and still kicking so I look forward to adding one to the Sorento.What do you recall High Performance? I wouldn't call K&N drop filters high performance but I have one in my 2013 and with the added MPG's and lifetime use it pays for itself so it was a no brainer decision...Hope that helps.
If it's good enough for our KIA Mechanic on Sorento Nation it's good enough for me....ENGINE PROTECTION LIMITED WARRANTY
Unlike many companies, our warranty for O/E replacement air filters and intake systems does extend beyond the replacement of a defective K&N part. For the original purchaser of the product, our warranty covers any engine damage or related costs incurred as a direct result of the use of a properly installed and maintained K&N O/E automotive replacement air filter or intake system on the specific vehicle for which the product was designed to be used by K&N. This includes reasonable vehicle repair costs directly related to an engine problem caused by the failure of a K&N product. Furthermore, we warrant that using our product will not result in a vehicle warranty denial. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages not listed above.
We will promptly reimburse the consumer for the cost of the repair if a service provider denies warranty coverage as a result of a K&N product or claims that a K&N product has caused harm to your engine or vehicle. In order to receive reimbursement, we require each of the following:
The consumer must provide a written statement or repair order from the dealership or service provider in which the dealership or service provider blames the problem or warranty denial on a K&N product;
The service provider or consumer must provide K&N with all allegedly damaged parts. Many states have laws that require a service provider to retain all parts replaced during a vehicle repair, unless given consent to dispose of the parts by the consumer. K&N will pay the shipping cost to recover these parts; and
The consumer must provide proof of purchase of the K&N product along with cooperation in helping us investigate the claim.
Once these steps have been completed, K&N will contact the service provider and collect evidence to support their claim. In the event we are not provided with sufficient evidence, we reserve the right to reject the claim and will use our best efforts to assist in establishing your rights toward the service provider under warranty or other provisions.
We strive to exceed consumer expectations. Customer service can be reached at 1-800-858-3333.

I have never seen the figures, but was wondering where you got your data. The K&N passes more air then stock. What is important is how many microns of dirt will the filter let past. The lower the micron filtration is the more crap it will catch. The lower microns of filtration will accumulate more crap.I'll provide a counterpoint. The K&N filter lets substantially more dirt into your engine than the stock paper filter. That is an undisputed fact. The stock filter costs $12 on rockauto.com and I change my filters once a year. So it takes a pretty long time to even break even when you consider the cost of the K&N plus the cost of the oiling kit. Why would I want to pay MORE and allow more dirt into the most expensive component of my vehicle?
That's simply not true. And the source of my data, performed according to ISO 5011 specs, was included in my posting above. Click on the link.Like most air filters available in the USA, our filters will provide all the engine protection you need.

Does a clean K&N air filter actually pass more air than a clean OEM type air filter? Maybe. Of course, this only happens at wide open throttle and high rpm. At any other time the throttle is restricting air flow (that's its job) so the air filter restriction is meaningless. And, at what point does dirt accumulation in the K&N make it pass less air than an equally dirty OEM type air filter? This can easily happen before the recommended cleaning interval.The K&N passes more air then (sic) stock.
