What does anyone think of the Ecotek CB26P & PX Filter...it's money back stuff and product liability
Does it actually make any difference

Hmm, I've not heard very good things about these, but if you do buy one, please let us know what you think.

interestingly ive heard some raving reports however the logic of it confuses me as you are bassically allowing unmetered air into the engine so the ecu has to use the lamba sensor to correct meaning it may doubt intake readings

Hullo!
Because I read that these valves can increase the torque a little I tried one out for my 1.4 8v!
They do help the car pull better when you put your foot down then release is slightly and fuel consumpsion is less also! My friend with a Honda Prelude fot about 17% more miles out of a tank of petrol (from 250 to 295 miles out of a tank!).
The bad news: it noticably de-tunes itself very quickly (although sometimes it's me using kack petrol) and I tend to have to reset it every 3-4 wks.
Overall: it's the goodness and if you're going to be a true petrol head then you should be checking your engine bay (at least to fit mods) at least once a month!

Kieth Lee rated it quite well when he had his red GT (the one D4VID now has). It does from what I've read make things torqueier in the lower revs, and I have also heard about the improvements on fuel consumption. The theory being that it allows more air into the combustion chamber to help burn off more fuel during one combustion.

the valves are manifold vacuum driven. vacuum is at its greatest at idle and part throttle, and at its least at wide open throttle.
based on that alone it cannot increase bhp, since its only active at crusing speed.

you could always waste a little money (some on ecotek, some on time and petrol) for science and the general knowledge good....... buy one, but give it the full scientific thing.
find a route where you can do 100 miles or so with not much interruption to a constant speed trek so that the results are consistent (say a motorway service station you can "loop" to between two far flung junctions - it'll be warm by the time you reach the start point, too) sometime at night... a couple times 50-ish, a couple something 70-80 (but choose a speed and stick to it!). use the same stretch, if little traffic and no plod/cameras to get an idea of max speed - and remember where you did that. find a suitable town route where you can trot back and forth on a set path at 20 to 45 between cameras, down side streets etc for maybe 40 miles to get rough town mileage.
then enlist a (right hand back-seat!) mate to time a few repeats of 0-30, 0-50, 0-70 (0-90?) and 30-50/30-70/50-70/50-90 stuff by the speedo on a measured flat surface in the dry (use spirit levels and sighting lines
)
maybe get it dyno'd, if you can be bothered/afford to. and have the emissions tested while you're there.
do that without the ecotek, to see what your "raw" car is capable of - and then do it all again with the valve fitted.
its the only way you'll know really - how do you know that new "punchy" feeling and reduced consumption isn't due to the (psychological) weight of the cash no longer being carried around with you and the car?
