For the MX-5 ND, the consensus usually leans toward a high-flow drop-in filter like the K&N or DryFlow rather than a full intake system. The stock airbox is remarkably efficient; aftermarket "cold air" intakes often just add noise without meaningful gains.

If you want a slight bump in induction sound and throttle response without the hassle of oiling, the AEM DryFlow is a solid bet. It balances filtration and airflow perfectly. Stick with the OEM box—Mazda’s engineers actually did a great job on this one!

For your situation, I've spent quite a bit of time messing with the intake on my own ND, and honestly, don't expect a night and day difference. But, if you want that extra bit of 'oomph' without a full swap, I'd suggest going with the AEM 28-50017 DryFlow Air Filter.

In my experience, here is why I'd go dry over oiled:

1. **MAF Safety**: I've seen too many people over-oil their K&N 33-5044 Replacement Air Filter, which then gunk up the Mass Air Flow sensor. It's a pain to clean.
2. **Sound**: You'll get a *slight* increase in induction growl, mostly around 4k RPM, but it's pretty subtle tbh.
3. **Maintenance**: Just wash it with soap, dry it, and you're good. No messy oiling required.

You might want to consider removing the sound tube if you want a 'cleaner' engine note too. Just make sure the filter is seated perfectly in the airbox or you'll get a leak. It basically sharpens the response *just* enough to feel it in your right foot... I think? GL! 👍

Quick question - before I dive into the deep end here, are you still under your factory warranty? Also, do you live somewhere super dusty or rainy?? I'm asking because I’ve been researching this a ton for my own ND, and honestly, coming from a safety-first perspective, there are some things you gotta consider before swapping that filter.

I love the enthusiasm for more sound, but I’m lowkey worried about your MAF sensor! If you go with an oiled filter like the K&N 33-5040 Replacement Air Filter, you have to be SO careful not to over-oil it after cleaning, or it’ll gunk up the sensors.

If you're looking for budget-friendly ways to get that growl without breaking the bank (or your engine), here's how I see the options:

1. **The Budget Dry Choice:** The AEM 28-50017 DryFlow Air Filter is usually around $50. It's awesome because there's zero oil to mess up your sensors. Super safe and reliable choice, iirc it's basically the gold standard for ND owners who want a bit more 'whoosh' without the risk.
2. **The Ultra-Budget Hack:** Some guys literally just remove the sound baffling in the stock intake tube. It's free! But yeah, it doesn't actually 'filter' better, just makes it louder.
3. **The Performance Oiled Route:** The K&N 33-5040 Replacement Air Filter (about $55) might give a tiny bit more flow, but like I said, the maintenance is the scary part if you aren't a pro.

Personally, I think the AEM is the safest bet for the money... but yeah, let me know about your local weather/driving conditions first! cheers 👍
