I don't get folk that think the eco-tek valve works. It is fitted onto the vacum hose of the brake servo.
The idea of it as that it causes the air going into the induction manifold to 'swirl' this is supposed to help the mixture of fuel to air. in theory it sounds like it could work in a standard engine but the setup instructions are hardly precision. It just seems to inaccurate to fit to a fully electronically controlled engine.
Turbo charged engines are forced induction which means an eco-tek valve will do nothing in these engines.
The question you have to ask yourself is if these things were so good, do you not think manufacturer's would have developed a similar instrument to fit into there engines considering how long they have been about for ?
On a finishing note, I had one fitted to a clio williams and I took it off the day after, the engine just wouldn't run right and that noise is a pain in the **** !
