I'm not sure if I'm allowed to give links as answers, but this is the best I've been able to find... although it's a decade old. Anyone have a newer test? http://forums.nicoclub.com/debunking-the-k-n-myth-why-oem-is-better-t180100.html

I would say stick with your OEM air filter if you don't want to think about any possible problem, and you "don't" need performance. Let me explain in details. Performance Air Filters (won't be giving brand names): They increase the air flow to the engine, so the car performance is increased. To increase air flow, they generally use cotton or foam filters, ...

I didn't see anyone mention it but I believe any increase in power would only be at wide-open throttle (WOT). So if you are racing or really aggressively pulling away from stop lights or accelerating, maybe it helps. Day-to-day driving at less than WOT the engine management system will keep the air-fuel ratio at an acceptable value. If it doesn't get enough ...

It depends. Just because an intake can flow more air mass doesn't guarantee that the engine will utilize it. The intake is part of a system of components. The engine produces power by managing air flow into and out of the combustion chamber. There are usually other actors involved: Intake side. Carburetors, throttle bodies, intake manifolds, intake ...

The working cycle of an 4 stroke internal combustion engine is like: (1) Inlet of the fresh air (2) Compression (3) Working Cycle - expansion (4) Exhaust Cooler intake air is especially beneficial for part (1). Since cooler air has a higher density, it means that the gas velocities at the inlet are lower. Therefore lower pressure losses at the cylinder. ...

Almost never? Mainly because they're really a 'hot air intake system'. This is especially true for cars using forced injection due to the high under-hood temperatures. If you want to reduce intake restriction look into a less restrictive 'panel' filter like a K&N. Even then, it really only matters if your car is intake (vs exhaust) limited and your ECU ...

Does this mod ever give a measurable increase in power? tl;dr: yes, sometimes it works well. But... Your picture is a good illustration of some of the problems with just saying "cold air intake" and expecting that to mean the same thing to all people. Let's break down the pieces of the puzzle and talk about how those might help or hurt: Filter: ...

The point is to feel like you've done something cool to your car and freed it from the shackles of The Man/the OEM intake. The primary benefit of Cold Air Intakes is to the bank account of the kit manufacturer, the secondary benefit is your car making a nicer noise, if you like the sound of an aftermarket intake. There's been a few debunkings of CAIs over ...
