Um sure like I said if you don't read how to use and service them, naturally if something goes wrong it must be the filter at fault .
but I understand the mentality of aftermarket performance part users.
FYI I had a product I engineered and developed and after so many customer could not understand or to READ the installation and use instructions and CAUTIONS to install with the RED arrow in the direction of the air flow that I finally pulled them from the market. ROLMAO.
I also have a couple of re-designed air intakes that if you use any other filter other then a K&N it will void the warranty and also you may not get any of the results for the air intake upgrade.

 

Maybe contact K&N and tell them what you posted here and please post what they respond to you with

You need to get all your information and facts correct a before posting BS. At least on forums that I belong to and it is several dozen! This is not my first or last time posting information often correcting poorly posted and none supported information from members.


K&N not only has one of the best customer service and technical advisors with great credential engineering and Certified Automotive Technicians but they have one of the world best R&D department. They also have a standing challenge to any air filter company that has any claim that their air filters are better and will publish all results to anyone taking them up on the challenge. To date not one other company has?
They also have more C.A.R.B certifications then any other air filter company in the world.
Duplicating their information on how they established gains results on at least and often times will results more gains and improvements then what they published.
This is also better than any other air filter manufacture in the world when comparing them.

Maybe they all read the installation and service instruction provided with their air filters?

Used as instructed and made nothing but mess. The worst is when people don't understand the car has a cold air intake and ends up with a silly hot air intake sucking oil particulate all through the ducts and intake valves. Outside warranty anyone can go ahead and mess up the engine all they want. But inside warranty, big risk. The Magnuson Moss Warranty Act allows for mods as long as they don't affect performance or reliability of systems as designed. Mazda and just about every mfg have bulletins instructing techs to check for intake mods including evidence of intake mods since they are responsible for most misfire incidents that cause piston ring damage and bent con rods. They deny the claim and leave the owner to argue it didn't cause the harm.

Again, just sharing experience and info since it was.one of the few things I agreed with Kilmer on. Didn't know you were really into those k&n things Callisto. I'm newer here to Mazda. I've read many of your great posts just disagree on this one... Anyone is welcome to investigate what my opinions and make their own decisions. You can even remove my thoughts if it is that upsetting. No worries.

 

Thats correct they are your thoughts not backed by real empirical data or information. I understand so well that many aftermarket parts do not work well for many people, in all my shops there is someone unhappy with some part they could not install or get to work properly. Most always was simply lake of patients, understanding what they were installing and reading the instruction.
TOP RETURNED PRODUCT of all time was the HOLLEY 0-1850 600cfm universal carburetor. The number one return reason "INTERNAL VACCUM LEAK". If you know carburetors that you know that statement is impossible. LOL And it was always from customers that thought they knew what they were doing and didn't read how to install and adjust the carburetor for their specific engine.
And if you have another part to post about ai am sure I can also respond to it as well. Been doing this performance parts gig selling since oh the late 70's. LOL

The OEM really is not a CAI that is a misconception. You really need to get out of the internet to find your information. The MAZDA Skyactiv air intake was designed to regulate the air temperature to improve emission and achieve the best MPG. This is not done by cooling the intake charge. If you were to actually monitor (I have) the IATs and compare most all so called CAI and the factory you would understand what I mean. Also would support that there is (Mazda skyactiv engine gas powered) not one CAI on the market that can achieve a cooler intake charge during city driving. The best can only come close to a OEM but the IAT will be slightly higher. Usually about 10-15 degrees of the ambient and more if AC is used or long periods of very low engine speeds and idling, like at stop signs. Frankly there is nothing truly gained from the aftermarket so called performance CAI except noise. The only true benefits over an oem are when engine speeds operated frequently at or near WOT and 95% or better Throttle position % on the drive by wire that is not re calibrate.
One of the many monitoring engine operations that I view daily is IATs (Intake Air Temperature) and fluid operating temperature's, oil transmission and engine oil also coolant. These all help me watch over my engine as well give me vital information about what goes on with a 2.5 Mazda Skyactiv N/A engine.

You are simply trashing a product with "your opinion", which you of course have a right to do.
You have, as yet, not offered anything but anecdotal remarks and zero factual evidence to back up your opinion.
Without actual results from certified testing of your use of said product, it remains nothing more than your opinion.
