Its what I neeeded, good price, good ship

Fits very tight and as someone mentioned it doesn't fit quite right. The top of the air box will have a 3mm gap or so from totally sealing. I believe it was more at first but the filter seems to be getting compressed down. It did require a bit of muscle to close the spring loaded tabs the first time but fitment got better after I checked to make sure it was still seated properly. I definitely noticed an increase in performance and my car was idling better. Well worth the money and a good basic upgrade for my 1999 Honda Civic LX.

El tamaño es 99% igual al original, queda bastante ajustado en la base del vehículo, se siente que la entrada de aire al motor es mucho mejor, parece que brinda más potencia al motor.Buen producto a mi parecer, buen material, mejora el flujo de aire, lo uso en un Honda Civic 98 DX.

Definitely felt the difference in the seat-of-the-pants dynamometer!

It's in my 2000 civic cx. Not a hot rod. No huge horsepower gain but I feel like I might have a little better mpg and maybe a tiny hp gain. Then again, it's probably the same. But if you need a new air filter, why not get the best? Take care of your cars and they'll take care of you!
