Nice price for a good product
Color: gray
They’re a great fit at a good price I’ve used them before and I put them in before I have my oil change done because otherwise they try to charge you like lots of money for both of those when it takes five minutes max to get them both in your car

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.
