I testet in 1.4 Ford Fiesta gasoline.
The fuel consumption was reduced > 5% after short time only 100 km.
A very good product.
Thank you and best regards from Germany.

Will test on longer distance highway of at least 100km and above in the new future

Overall given its reasonable price point, I guess is no harm fixing it
