Excelente producto y llego en un tiempo record
El producto es acorde a las especificaciones, llego mas rapido de lo esperado, estaba programado para llegar el 22 julio y llego el dia 19, el embalaje un poco ordinario para mi gusto, sin embargo eso no afecta la calidad del producto.

Slightly satisfied
After a couple of months I'm getting the same fault code. The engine light resets on occasion but always returns. I'll try a different brand next time. The driveability is still good though.
