Does this airfilter have the same mesh size as the factory filter, if not you are going to be sucking in larger particles which will wear the engine out faster. You shouldn't be able to hear the sound of the air intake as this after time particularly onna long drive can become quite wearing on you, same with a nousy exhaust.
Next you be saying you need to upgrade your stereo bcause you cannot hear it above all the nose the car is making, this will lead to early deafness in later life. With a low down air intake , if you catch a splash of water and it enters your cylinders then its bent conrods. So be carefull with these mods. Companies have been selling these type of snake oil items since the 1970's. A noisy engine doesn't equate to more power. Never believe half the marketing. Have you had the car on a rolling road, before and after mods?

 

I have a water-resistant cover on the cone filter to prevent water from entering the intake, and it's in a fairly sealed location. So I'm not worried about water issues.

As for the sound, I love it, it's there but not intrusive. You really only hear it loud when you get in the gas. Otherwise it's barely noticable with the windows up, and I can't hear it at all with the radio on.

I don't think this intake is snake oil at all as it genuinely puts the filter in a better position to bring in colder air than your standard short-ram intakes do. And, as I said, the driving experience is greatly improved; the turbo lag is all but gone and it's much more responsive. It's very well made and study when installed. It doesn't move at all.

 

If a filter lets air in, what's to stop it sucking water in if its deep,enough. Your water resistant cover looks more like a hotel shower cap for the ladies.
If the volume of your radio is that loud to drown the sound, then its too high and will damage your hearing. I don't have any turbo lag on my 2.2d as it has two turbos in series. And do I really need to accellerate so fast from rest. No. Do I need the car to be noisy for everybody else. No.
Noise also changes to vibration.
Have you had the car on a dyno before and after fitting this snake oil and what difference did it make?
My air intake is behind the 2"diameter circle in the picture, it gets plenty of cold air.
If you live in Michigan there must be an abundance of cold air for 9 months of the year, in fact freezing air.
If you have an intercooler after the turbo, that will cool the air down going into the engine as its in front of the radiator, plus for emission reasons, the EGR valve opens to add heated exhaust gas into the inlet manifold and hence the cylinders. As far back as 1984 and perhaps earlier ther was EGR valves fitted to cars in the US to cut down on pollution.
Mazda has spent many manhours in designing cars to meet emissions regulations, reasonable fuel economy, driveability, quietness for not just the cars occupants but pedestrians ( ah! Americans are too lazy to walk, maybe doesn't apply), longevity of the engine by having a large area fine mesh air filter, rather than a small one with a more open mesh which allows larger particles into the engine and cause wear to turbos, valves, piston rings, liners etc. I see you have to clean that filter frequently, whereas a standard filter is changed every 24K, but can be vacuumed quite easily everytime you vacuum the interior of the car.

But some snake oil company comes up with a convincing marketing spiel to convince the gullible to buy one. Stuff like this has been around for years. If it met the Mazda's or any other manufacturers criteria it would have been fitted.

You will learn as you get older, we all went through that stage when young.
Same as why do you need an airfreshner in a car or a house, because it needs cleaning and ventilating, throw away those fast food wrappers, don't smoke, open windows. Only dirt smells. Air fresheners only dull the the users smell sensors, the McDe smell is still there, or *** ash.

 

I'm not reading all that, I like it and I don't really care if you do. Do what your want with your car, I'll do what I want with mine. Please do not comment on my posts anymore unless you have something relevant and useful to add. Thank you. 😁

 

My comments are relavent otherwise I wouldn't have commented.
