Great purchase!
Size: 1.9" x 9.9" x 11.4"
This has worked out quite well. I have had it since 2023 and have been cleaned thru about 6 maintenance schedules. It's been 2 yrs and it's in great shape. Worth every penny.

Really filters the cabin air
Size: 1.9" x 9.9" x 11.4"
K&N filters are always a cut above. Can’t say the same for service/support after the sale.

IMPRESSED!
Item Package Quantity: 1, Item Package Quantity: 1
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.
