K&n Filters ?

[carlos_vini]

I WOULD LIKE TO KNOW IF SOMEBODY USES K&N AIR FILTER IN ITS CAR

I WANT TO BUY ONE FOR MY STARLET REFLET F 1999 AT EP9 , I WANT TO KNOW IF IT SOUNDS BETTER, IF IMPROVES THE ENGINE O SOMETHING LIKE THAT

It sounds a tiny bit better, it makes the engine a tiny little bit more powerful. It won't make a huge difference.

One benefit of a K&N filter is that you don't throw it away - you wash it and re-oil it. This reduces servicing costs.
