Re: should i upgrade to a cold air intake

Honda engineering did a fine job with the intake. Invest in a K&N filter and change your fluids!

K&N filter??
you be the judge:
Filtration Testing for Amsoil, K&N, Napa, Jackson Racing, Baldwin, and Mazda air filters on a Miata

As for the intake, either keep it stock or get yourself a Type S intake. (remove the resonator)

Re: should i upgrade to a cold air intake

That is a weird test if I ever saw one, a visual inspection of how dirty a filter is after use is not really indicative of how it has performed. From my basic understanding (more in the HVAC industry at least) a filter medium is graded on it's arrestance (ability to stop particles moving through), but two filters with the same rating can have different pressure drops, but a filter with a lower rating will let more of the smaller particles through. The lower the pressure drop through the filter the better the engine can breathe. As filters fill up with dirt the pressure drop increases too. All this is mentioned briefly in the article though. BTW, a filter with the same filter medium but a larger surface area will have a lower pressure drop since the air will pass through it slower. So which has more surface area, the stock panel or a pod?

What he should have really tested in the article is the clean filter pressure drop, pumped a measured amount of various grades of dust and dirt through to see how much is caught, then measured the pressure drop again when dirty.... but who the hell is going to go to that much trouble when the "real-world" test showed only a minuscule variation.

Conclusion, it doesn't matter which "performance" filter you get (just don't get a 2-stage), the important thing is to always keep it CLEAN. I can vouch for the K&N that it is a great filter and is very easy to clean, the recharge kits make them good as new.

Anyway, I agree that the stock air box is pretty damn good (thanks Honda). Technically it is a CAI since it draws air from under the car anyway, so why pay for something you already have? I wouldn't recommend deleting the resonator if you plan on driving the car through a foot or more of water though.

Re: should i upgrade to a cold air intake

If the Honda paper and K&N have the same pressure draw or very similar I'm going with the washable one. The Honda one is a one time use type. I can wash the K&N filter everyday if I want to. The Honda? Well you can whack it against something to clean what will fall off... I'm still using oem simply because I had a six pack. But when they're done, it's a K&N going back in the stock air box.

Pretty much got flamed for driving like a jackass and was told to slow down. And I'll be damned, slowing down fixed it.

Re: should i upgrade to a cold air intake

Only advantage the K&N has over OEM is it draws in more air but I'm quite sure the OEM filters much better then the K&N.

If your worried about cost, geez, you shouldn't be driving if you can't afford to replace a $20 OEM filter once a year.

I guess it has to do with preference, would you rather have the air filtered more efficiently or just more air flow entering the intake which isn't being filtered as much as the OEM paper filter.

This. I'd rather be able to service my own filter as opposed to replacing it every year.

But thats not saying there is anything wrong with the OEM filter. It is what it is. It all comes down to personal preference.

And just to be clear. An increase in air intake volume doesn't mean di*k unless you're tuned anyways.
