1.8L 4 cylinder turbo - coming from an extremely glogged air filter and going to this was a game changer. Car performance increased and airflow and even shifting performance was much better. Easy to install and even came with the proper adapters for the installation. Which I needed all of them due to the engines small intake. Great buy!

Great filter. Been using this same model filter on several cars since I was a teen. Just make sure to clean it 2x a year, don’t wait for the recommended interval. Clean and oil it properly, and it will last.

Looked like a K&N but the lettering on the filter wasn’t crisp. Some gas leaked on it when installed and the rubber melted in less than 5 minutes. Called K&N and they said their filters are impervious to gas, alcohol nitro..

エアクリーナーといえばこのメーカーでしょう車種別設定品などは値段が張りますが洗浄すれば繰り返し使用できる、長い目で見ればコスパも良し、製品のクオリティも文句なしです
