Would adding a K&N filter to a normal unchipped 2.2 TD4 make any difference to MPG

Averaging about 24.6mpg between fill ups doing mainly town driving and look at ways that won't throw away my warranty to increase it slightly

You could try filling your right shoe with broken glass.

Just looked on K&N site and they don't even list a LR2 with a TD4 engine as they are an American site, they also have no filter for the 3.2 petrol

I have seen them on eBay and someone on here put one in

Not actually checked k&n website yet Former Mod/Member, with the most post & Chicken George Arch nemesis

k&n do one for the petrol and it fits the diesel too. dont know if its the correct filtration air/flow for the diesel but it fits the airbox. someone on here go one I think?


edit. http://www.freel2.com/forum/topic3489.html?highlight=filter seems its good for both diesel and petrol fl2's

No, but will probably save you £7.24 every service if its a K&N lifetime fit one.

I have one that i got from tatbay,made no differance to mpg at all,but made bluefin upgrade seem crisper but without dyno info would be hard to prove.
Cost me about £40,thats the same as 4 new genuine filters? I will need to clean it and reoil it at the next service though ,kit to do this cost me a tenner,(tatbay again)
on a positive note I was pleased to find out that others get worse mpg than me though!!!! (28mpg is norm)except when towing the caravan 24mpg,mind you i bet chickin dung dont get that from his tractor!!!!


Happy EBAYING!!!

the difference is my tractor is serving the country by providing food, where as your van is costing the govt money by slowing traffic reducing safety camera revenues and making people late for meetings. At work

Averaging about 24.6mpg between fill ups doing mainly town driving...

According to my calculations (450/460 divided by 14.298), I'm averaging between 31.4 & 32.1 mpg.
Strange, as the onboard computer says I'm averaging 29.8.

This is a mixture of town & fast dual carriageway driving.

That's manual calculation on a fill up to fill prog I have on

Average over the first 1500 miles is 36.8, wouldn't bother with K&N etc. filters, initial 'improvement' is great, soon degrades after that but gradually so not noticable, paper filters provide better filtration (therefore less engine contamination & wear), top tip to extend their life is to rotate 180 degrees
