We are always striving to improve our products and our new updated V2 High Flow Air Filter for the Focus ST and RS includes several enhancements that substantially enhance air flow compared to the standard filter and even our previous version.

Improvements include a unique smooth radius in the primary inlet port providing an efficient transition for air flow along with a shorter inner filter cone to allow maximum air velocity and flow directly to the inlet port.

These updates coupled with double layer cotton gauze with deep pleats that creates a 10-15% increase in filtration surface area compared to other filters on the market. The oiled filter media is incapsulated in steel mesh that helps to maintain the perfect shape under the most extreme conditions. Each mountune filter is manufactured using a four step process resulting in a precision fit and virtually no seepage of rubber frame material into the filter media producing the maximum available filter area.

Please note for Focus RS, replacing the original air filter with a high flowing unit may cause a whistling type noise on some vehicles. Please see our Sound Suppression Chamber for more details.


  • Improved Air Flow
  • Pre-oiled
  • Increased performance
  • Lifetime warranty
  • Made in USA

5 of 5 The fit is very good March 25, 2020
Reviewer: Chad from Mabelvale, AR United States  
Fits as good or slightly better than own, no issues sealing tightly and tolerance to fit the airbox is great. No issues installing, it is a bit louder "inhale" sound from the engine, I'm okay with that. Good to know the engine is breathing so well

Reviewer: Michael Clements from Lewisville, TX United States  
I really like version two of this filter! Adding the filter seems to have improved power at higher revs.

5 of 5 Perfect March 9, 2020
Reviewer: David Hamilton from Long beach , CA United States  
After pulling out the factory air filter which felt like cheap paper this filter really let the engine breath. Added to that it gave it a nice whistle and the I can here the turbo whoop whoop whoop(sound effects). Great product only complaint is that i didn't get a mountune sticker with the air filter!

5 of 5 Great replacement over stock March 3, 2020
Reviewer: Robert R from Plano, TX United States  
Easy install. Turbo/ intake noise more noticeable. Just by looking at it you know it flows more air over stock.

5 of 5 Good product at an excellent price. February 12, 2020
Reviewer: Christopher Scott from Nicholasville, KY United States  
This was purchased to replace a missing part in an existing Mountune kit.  Part fit perfect and eliminated the issue that we were experiencing with fit and finish.  The only complaint was that the part was ordered before Christmas and was finally delivered in Feb.  Now Mountune was very on point and informed me that there was going to be a delay in getting this part... just wasn't aware it was going to be a 60+ day delay.
