I work on the theory if these things were so good manufacturers would install them . It has yet to be proved a bit of bent tin can improve fuel consumption by 25%
Despite you installing 2 of them, Did you get 50 % improvement.
Like Sonic snake repellers I simply wouldnt waste my money.
Hiclones and Peter Brocks Polarisers are snake oil in a different packet.
A bit like taking part in a drug
test Half are given sugar pills but still say they made a marvelous difference. Because they want to believe it does.
Half a litre difference over 100km is nothing and could be attributed to different temperatures, different traffic conditions and if thats all you get wouldnt be worth the money.
