I'm evaluating replacing the original (engine) air filter with a K&N air filter. My CX-5 is turbo, so there would be any noticeable difference in performance that is worth changing or should I keep the original?
I put in an AEM dryflow filter for my non-turbo. At best, it feels a bit more responsive off the line and when I need to punch it. At worst, I'm sure it's not filtering as well as a result. I feel like the NA engine breathes a little easier and being at higher altitude, I feel like I felt a difference going to it from the OEM. But I'm also sure that extra breathability has a trade off in filtering ability.
Going to see how my next UOA (I still need to mail off my last one, oops) turns out and either keep with it, or go back to OEM. I bought it primarily because I liked the idea of one filter I can wash and reuse. I think I'll be ok being garaged and not driving on dusty or dirt roads anymore. I didn't really get it for any perceived performance increase. As for the K&N, I've read too much stuff online with people over oiling, or even just as its supposed to be messing up their MAF sensors. No thanks.
K&N filters make an awful noise. Vehicle manufacturers spend a great deal of time suppressing intake noise.
Sounds beautiful to my ears.
Same here. But, when you consider the market the CX-5 is marketed to and the direction that the company is going, Anchorman makes a great point. All that sound insulation is redundant if you make the sound coming from the engine bay louder. All depends on your personal preferences.
Also, remember there's no magic filter. If it flows better, it filters less, and vice versa. The paper stock ones are a great trade off and are cheap & easy to find at any auto parts store.
Not necessarily.
My company developed a new filter media to replace existing.
The new media is lower restriction and higher efficiency.
This is for diesel engine filtration, but not for automotive applications.
