The old arm was replaced and the new one fits perfectly. No engine light anymore, the car runs well, great!
Easy to install, grease may be required to install the bottom joint. Be careful when installing. There are some plastic pieces. If you are not careful, the nearby area can crack. If you crack, the entire intake manifold may need to be replaced.
The quality is very good. It feels the same as the original factory. It can be used normally after installation!!
