About the intake maniforld

Hello there! Friends. 206 1.4 petrol lpg 2006 model car was overheated engine was out of renewal, everything was renewed, now it is being placed in the car again, one problem is that it is very expensive in the orgy related to the suction manifold, it is expensive in the ital one, and nobody advises me to buy it. Is there a difference is the health of the vehicle is going to have an effect on fuel consumption?

I do not know much, but you will find out of the chrome manifold made later.

I learned that I was going to make 250 liras with chromium-absorbent maniforl.
