I bought this for my Honda civic 2017 lx 1.5 and it is a perfect fit. I didn’t realize how important it is to change it. Let me tell you if you are thinking about buying this, it’s your sign not JUST because of health which is vital and first and foremost but the PRICE! At any oil change or auto shop they will charge no less than 50$ and I’ve seen higher. I will continue to buy this brand. I will update in my next 5,000 miles. 8.00$ or 50$+ and the quality is EXACTLY the same, your choice.

Fits perfectly in my 2016 Honda Civic EX. Installation was quick and easy, and the air coming from the vents smells much cleaner now. It seems to trap dust and pollen well and is a good replacement for the OEM filter.

Perfect fit and reasonable price. Easy to replace in my 2019 Honda CR-V. It takes about 10 minutes to replace. Don't let a dealership rip you off.
