I use one in my 99 PAJ, in conjunction with a "Finer" filter. Appears to give more power and the fuel economy is better.

raybates I think you'll find that they don't stand up to any scientific tests! Beware of the "appears" to improve type reports - always very short on data. I tried a similar product on an HQ Holden many years ago, also took the fan blades off - neither improved although a friend assured me he gained 4mpg by removing the blades!! Didn't stand up to even the simplest scientific analysis. You must test with and without under as close as possible to the same conditions (wind, terrain, speed , driving style etc) ... but most people don't do that. Some will even claim huge improvements in fuel economy by changing brands of fuel (they don't realise how few refineries there are and hence many fuels come from the same source!!

used one on my 3.5v6 Jack, made only about 1% difference with stock air filter, fitted a unifilter foam element and removed hiclone and found far greater improvement. Just reinforced my theory that any restriction in the intake manifold system is not good. Am going to sell the hiclone and put cash toward custom headers instead. Stick to tried and true methods of increasing engine efficiency - intake / exhaust/ spark etc. Brad

have one on my gq 4.2diesel, no extra power as claimed, a slight improvement on fuel consumption, equivelent to running car with the aircond on all the time, i did do the maths once and it worked out that i had to do 47,000 clicks for it to pay for itself in fuel consumption alone, not what i would call worthwhile and it only really made a difference on the highway, nothin around town

Raybates, as Truckster says, there's plenty on this already - just do a search. I claim they work in my EFI ULP V6. Others have put forward solid arguments as to why the wouldn't work, especially in a diesel.

I got two in my GU 3.0 and the turbo cuts in earlier, 2-3 l/100km easier on the juice (down to 10.5 on a trip now) and smoother idle and running, similar resulkts from my mates defender t/d.

But a mate with a 60 series has head no joy, petrol motor sucks the fuel.

As truckster says, some boys do...some boys dont....

I only tried them cause they have a money back guarantee and they meant it

All the bestSo many places to go!
So much work to do :0(
