Tried one on my old 1.4 8V but engine wouldn't run smoothly unless the valve was shut off so gave up. If you buy direct from ecotek they will refund the cost if you're not happy with it and it's a promise they lived up to as well.

its loud an anoyin, somtimes it will whistle an that really pist me off, i locked mine off totally, just got it in for looks now with the filter on it, looks ok! made a small diff on my economy, about 10miles extra per tank!

i had one on my 1.4 16v. Didn't notice performance improvement but it improved the fuel economy a bit.

Noise on overrun is a bit annoying, and I found the 'silencer' actually made it louder.

It basically bleeds small amounts of air into the inlet manifold that makes it leaner, and so uses less fuel.

excellent site with all you need to know, and pics of different fitments

ecotec = vauxhall/opel engine type

ecotek = aftermarket valve which apparently improves performance and economy

DONT CONFUSE THE TWO

dont corsa c's come with a ecotek engine???

they r meant 2 b shit hot exept 4 the noise, u can get the filter and the device cant u, there lik 46.95 or sumin like that.. im def gettin 1... ohh people have u heard of these "surbo" units 2??

my cousin has one on his saxo, he gets a lot better fuel economy. The only problem is, the stupid fukin valve sounds like daffy duck!

I thinkhe means an ecotek fuel widget they are worth the money they make fuel consumption more efficient my mate has one on his nova an i wud defo get one as he said he's noticed a real change does make a funny wirring noise he said tho but u can hardly notice it if ur induction kit an zaust are loudish. Not sure if you can get em for corsa c tho look in maxy p or fast car to see where sells em then give em a ring:!
