so here, I do not know if it is the section aproprie but I still try my luck, if it is not, thank you to tell me
I have a 406 3.0 V6 210 Chevanux, I like this car, but, alas, it consumes a lot and therefore pollute accordingly (not to mention the financial aspect)
what can I put to make it less?
knowing that I drive in "ecological" mode I do not pull on the reports, (except during the madness

-a vortex valve system?
-a "turbulator"
I read a lot of post it and I can not understand the operation of the turbulator, as well as its location
the gain aporté etc ....
if you could enlighten me
cordially
Mathieu
