"I was sceptical, very very sceptical. This simple device promised great things for under £50: lower emissions, reduced fuel consumption and possibly better performance. If I'm honest I went ahead fitting it with the intention of alerting the public to yet another bogus product. But I was very wrong. Fitting takes a couple of painless minutes and the improvement was immediately apparent. My car now feels less breathless at high revs and seems to pull stronger than ever before. I've had it fitted for a couple of months now and am more than pleased with it. The only slight downside is the sucking noise the ECOTEK creates when I lift off. It's not too unpleasant though and I've been assured that it's simple to silence should I decide I want to.

Rather stupidly, I've been driving the car with increased vigour of late thus cancelling out any potential fuel savings. I certainly haven't noticed the consumption being any worse though, despite my best efforts. ECOTEK Technologies Plc have loads of information backing up their product, including an impressive full test by the Department of Trade and Industry. So if you want to save cash on petrol, drop your emissions and pep up your motor's performance, you could do a lot worse than getting your hands on one of these.

VERDICT: SIMPLE, CHEAP AND, IN MY CASE, EFFECTIVE." Dan White - Redline

"I've got to admit it, I was interested in this Ecotek CB-26P. The device claims to reduce emissions and fuel consumption. Bold claims, and cheap at the price if they're true. 

The unit fits into a vacuum servo hose close to the inlet manifold and is a non-return valve which injects minute quantities of agitated air into the manifold at certain pressures, This leans the mixture very slightly - the quantities of air involved are about 5% but they are sufficient to create the turbulence necessary to produce improved combustion efficiency. Anyway less of all that techno babble, does it do the business?

We took a couple of Ecotek unit's along to our spanner wielding chums Supamek where we tested the product on an '87 1.4 Astra. We ran it up on the MoT emissions tester and come up with a CO figure of 1.32% volume, and a C02 reading of 14.1 % vol, It took us five minutes to fit the Ecotek, and the results were good, 0.47% CO and 12.3% C02. a marked improvement all round. After a quick test drive, response was up and the car pulled through the gears much smoother.

Not content with just one test Danny from Supamek also fitted one to his Calibra, having no emissions due to the fitment of a cat. These were his conclusions:

'When going up through the gears on the rev limit the car used to die momentarily as I changed. It now pulls cleanly and I'm well happy - a chip upgrade does the same job. So I reckon I've saved about a £100, which can't be bad'

Fitted to everything from Bentleys to Corvettes, these things work. If you don't trust us, you'd trust the Department of Trade wouldn't you? Even they liked it."  Bryn Musslewhite - REVS

STREET MACHINE magazine - February 2002

Here are some wise words from Jon Betts of Street Machine magazine who fitted the device to his Chrysler Neon:

"I'm sceptical when I read about products that improve performance and economy etc.. so when I saw the new Ecotek device and the rave reviews it had received, I was keen to try it out for myself.

Fitting the device was a doddle as all you need to do is cut into brake servo pipe close to the inlet manifold and install the valve with the aid of a couple of jubilee clips. The noise is the first thing you notice; after blipping the throttle there's a sound not dissimilar from the sound of someone finishing off a McDonalds milkshake! The small filter from Pipercross goes a long way to reduce the noise but you still get a few strange looks from pedestrians.

On the road you can really feel a difference as the Neon is much more agile going through the gears. As yet I haven't put enough miles on the clock to check the fuel figures but I'll report on these next month"
