2024+ Mustang GT Air Intake Filters

[dusman59]

I would think the area you drive as well as miles. Here in the AZ desert there is plenty of dust. Back east lots of pollen. Having salt spray from the Car in front might tend to dry and effect filtering. Cleaning isn't a big deal.

can you give an estimate of how many miles before a cleaning is needed? i could handle 2x a year.

I’d start with 5000 miles and see how they look. It depends a lot on where you live and the conditions you drive in.

I do not. I would check flange dimensions. Our filters are the same as the OEM (5 inch diameter flange). As long as the aftermarket intake uses 5 inch diameter flange and have enough space for the filter, they will work. Intakes with different boxes will likely have a different size or shape filter and is unlikely to work.

I think the Steeda intake, Roush lids, and the SPE intake linked above will work but have not been able to confirm this.

The SPE intake in forge carbon fiber is on my dream list.

These filters will not work with the Steeda intake. Their MAF housing is significantly larger than stock

the reason k and n are used in offroading is that it’s a 3d media that holds a lot of dirt before restricting flow. your filter appears to be 3d media. why do you feel it needs to be cleaned more often than the stock paper filter needs replacing?

The media is very different between our filters and K&N. These filters use nanofibers that are orders of magnitude smaller than the cotton gauze used by K&N or the OE paper filters. This allows us to go thinner on the media. Since these have a very high filtration efficiency, these may need to be cleaned more often.

Just ordered mine for my 60th anniversary.

k&n makes a filter minder pictured here
you plug it into your intake
it measures negative pressure and tells you when your filter needs to be cleaned.
perhaps this would help here as well

Mine arrived today. Very well made. I am impressed.

another way to assess if the filter needs cleaning is to look at the intake manifold vacuum pressure. as the filter clogs, the pressure should drop. here is a pic of the pressure at 3k rpm. maybe check a baseline when filters are new and check it every few months

Thank you to everyone who has supported our business or engaged with us over the last year. 2025 was a great year for ThInK Auto Tech and I am very excited for 2026.

I announced that the price on our filters were going to increase but with so many orders coming in at the end of the year we held off. Price increase will take effect on Monday.

In 2026, we are going to focus on bringing a couple more filters to market. We have been working on a few other parts for the S650 Mustang but have not been able to put the amount of time into these projects as needed.

I’m interested in how these compare. Both seem to have similar claims of top tier filtration. Also curious if there is any numerical data to compare either filter’s, or any reusable filter’s, filtration to OEM.

I noticed this RAH filter claims “ultra fine cotton fiber”. I’m assuming there might be benefits to the ThinkAuto synthetic structure, maybe like fiber uniformity and/or less restrictive for similar filtering performance?

Any info on this would be greatly appreciated.

Maybe this will help...

Spent some time on the dyno today. Given the filtration efficiency of these filters, I did not expect any measurable gains. I was very surprised to see ~5 hp gain over the stock filters. Saw more gain with the hood open and the lids off of the intake boxes as well.

We did 2 runs back to back for each setup in track mode. Runs were done in the order below with 10 minutes between stock and ThInK Filters being installed.

1. All stock, closed hood, closed intake box - 380 whp (corrected)
2. All stock, open hood, closed intake box - 381 whp (corrected)
3. All stock, open hood, open intake box - 386 whp (corrected)
4. ThInK Auto Tech Filters, open hood, open intake box - 393 whp (corrected)
5. ThInK Auto Tech Filters, open hood, closed box - 387 whp (corrected)
6. ThInK Auto Tech Filters, closed hood, closed intake box - 385 whp (corrected)

Filters are in production. We are getting close. Once I have a date for delivery, we will open sales.

Which grill do you have? (comparing run 2 vs run 3).

Air filters are installed and they look like like some high quality filters for sure ! After the grille airflow modifications I knew I needed something more durable than factory. I made this video mainly to talk about the grille change and if it helped lower IAT at all, but I also include the air filters as well.

The S650 MAF's have a high-temp “burn-off” (self-cleaning) cycle after shutdown to burn contamination off the element, which eliminates the problem of an oiled K&N style air filter fyi.

Stock grill for the dyno runs. All runs were performed back to back to back on the same day.
The main takeaways that I had from this are that there was no loss of power throughout the rpm range with the ThInK filters and that running with the hood up and no lids on leads to higher results than what will actually be seen when driving. Meaning you should always dyno with the lids on and hood closed. Open box intakes that seal against the hood especially should be ran with the hood closed for more accurate results.

I cannot speak for the other companies product but seeing that large of a cost difference means you are giving somewhere.
