I have 2 installed and I think it works and does something...but something is better than nothing

much like brockies polariser (anyone remember that???)..........if you think it will do you good then get one.............mine now resides quite happily swirling the air on the bench in my garage.......after 10 years there was no damage to the engine - that's the best that can be said.......rgds

Yeah I have 2 in my GU, can't say I can notice any difference, they come with a ten day or soemthing like that mone yback guarentee, but I guess I couldn't be bothered removing them once they were in.. Personally I wouldn't rush out.. If I had the time I'd have sent them back and got my $ back. no noticable diffenrece on my part.. thats not to say there isn't one, but I hguess you would need a computer test gear etc to notice the difference.. IMHO I think it's worth putting the money towards a bigger exhaust system FWIW...

Used it on an old commodore when I was young and niave , you are better off spending your money on a good filter like K&N or some cold air induction like a snorkel, they offer guaranteed performance benefits, although dearer.

I don't have one but i know someone who put 2 on and gets an extra km/l now so very happy.

Before i tried them i kept a record of fuel consumption and noted my driving habits for four tanks of diesel. After i put them in i ran them for three tanks and noticed no difference. This was in a 1995 troopy, Personally i would probably spend money on a KNair filter or change driving habits. I sent them back within thirty days and had no trouble getting my money back. It was about $330.
Happy days

Thanks everyone. I won't bother with these.
