It fits perfectly- as mentioned by others the only way it fits in this car's air box is to turn the filter 90 degrees so the filter slats are running vertically, not horizontally as it does on the OEM filter. The filter looks square but is not a perfect square. Build quality is much better and more solid than the flimsy OEM or aftermarket paper air filters. The deep side of the filter (air input) faces the front of the car which I installed into the front portion of the air box. I noticed right away that throttle response was better and much more immediate, and the engine sounds and runs more smoothly. After 2 weeks of having it installed acceleration and power have really improved. The lackluster acceleration was a drawback I've had with this car in exchange for good fuel economy, but I love everything else about it. After having had the K&N filter installed for 2 weeks acceleration has really improved to where I am very impressed and am having even more fun driving it. This is my fifth Subaru with the 2.5i engine. I was thinking my next Subaru would be with the 6 cylinder but no longer, thanks to this air filter. Apparently the engine computer system needs time to adjust to the increased air flow. This is not imagined on my part, power and speed have considerably improved, as well as smoother acceleration. Feels like power has increased by several horsepower. The car also idles at a lower RPM. I have not yet determined any increase in fuel economy- I've been having too much fun driving this car faster and harder than before. This filter really does great things for my car's performance! Don't hesitate to try it. ## Features - ULTIMATE LONGEVITY: 10-Year/Million Mile Limited Warranty protects for the life of your vehicle - ENGINEERED POWER: State-of-the-art filtration media provides up to 50% more airflow than disposable paper filters to increase power and acceleration.

Passt einwandfrei, Macht etwas mehr Ansauggeräusche und lässt die Luft mit weniger gegendruck fließen. Mehrleistung hab ich aber nicht wirklich gespürt. ## Frequently Bought Together - K&N High-Flow Original Lifetime Engine Air Filter: Increase Power: Premium, Washable: Compatible with 2003-2021 Subaru: (See Product Description for Select Models) 33-2304 - K&N Premium Cabin Air Filter: High Performance,Washable, Clean Airflow to your Cabin: Designed For Select 2008-2019 Subaru (Levorg, XV, Forester, WRX, Crosstrek, Impreza), VF2055 , Black - K&N Air Filter Cleaning Kit: Aerosol Filter Cleaner and Oil Kit; Restores Engine Air Filter Performance; Service Kit-99-5000, Multi --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/260242428-k-and-n-33-2304-high-performance-replacement-air-filter](https://www.desertcart.com.cy/products/260242428-k-and-n-33-2304-high-performance-replacement-air-filter) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-05-06*
