I don't think that the fact that I live 4m below sealevel is the answer as I have the same problems in Austria were I am working now. I found that Germany must have the worst mpg eaters as it is even lower there.

Ireland 2005 Discovery 3 TDV6 Base 5 Seat Manual Tonga GreenDiscovery 3

Update!


2 weeks now since I fitted the RAI and mpg up to 20.1

So Discowex kindly offered to swap the top of the unit with me for a period to see if any improvement....mini experiment so to speak. He'd fit mine and see if reduction of mpg in his motor etc


we swapped the tops and I reset before heading home......now reading 24/25mpg consistently for yesterday and today. see how it goes for the rest of the week end I'll report back.

One big difference is the noise now of the unit with the slots, maybe thats why they changed the design on the new ones?

Hmmm! Not noticed the noise with my (slotted) RAI. Then again, it has been fitted since new (and I normally drive with the windows closed to keep the heat out). Whistle

Germany 2008 Discovery 3 TDV6 SE Auto Zermatt SilverDiscovery 3

1. Mine attached by LR 3/2008 has holes....

2. to compare Liter/100km to mpg => please confirm you are talking about gallon (US) approx. 3,7 liter since there is also a gallon (imperial/british) in my conversion tool which is 4.5 liter....

in regard to gallon(US) I get 32 mpg including german motorways. This is without speed limit and MT tyres and RAI on the car.

Sorry for digging up an old thread. All you guys with slots in your raised air intakes have you also got the grill bit at the back as well? And tanters did you cut slots in yours in the end then?
