right i get u now but i did say most vauxhall, not other makes. the 1.2 new 1.4 and one litre rita's all have a very close afr to 14.7:1. obviously for bigger turbo applications itll b different like u say. dont matter what it is really cuz petrol is still too friggin expensive!!!!!!

use more fuel with a different filter bcuz an aftermarket filter allows more air in, the mass air flow meter reports this to engine ecu, and then injection ratio changes to compensate. its called the stoichemetric ratio(air and fuel quantity). and on most new vauxhalls the ratio is 14.7 parts air, to 1 part fuel.

you'll find most cars don;t actually run this. and you've got no chance of a forced induction car or one that revs a lot

yeah thats what i thought prob only use more cos u drive diff due to the induction kit, but if u drive the same u reckon fuel consumption will be roughly the same??

cors_sxi thats shite man i thought mine was bad but on 30 quid i get 350 miles, u must seriously boot it

might be better on a 1.6 as you don't have to rag them as much to get upto speed

i only get 240 miles for £30 :( without ind kit on my 1.2 lol

feck that jesus didnt think it was that bad with my 1.6 id be fecked esp as i do bout 200 miles a week

i lost about 60 miles off a full tank just driving normally with a piper x induction kit.when i ragged it did about 100 miles to £15

is it a noticable diff or it depend if u rag it every where ???
