I put a K&N in my Defender 3 years ago. It seems to have improved the power and mileage. But then again, couldn't you swear your truck runs smoother after it gets a nice wash inside and out?
If anything, the K&N filters better, and you don't have to keep buying new airfilters whenever it gets dirty.

agree
I agree if nothing else it will be a cheaper air filter in the long run
I have run K&N on performance cars and noticed a difference but I was running a K&N pod filter on my 1990 rangie and didn't notice any real change

Given that I believe there to be some merit in the first statement the second is likely only to be true if you own the vehicle for a short time or drive it primarily on the street as opposed to the less than ideal dusty conditions found on most of our back roads.They do not filter as well as paper.
They are cheaper in the long run.
If you do any offroading stick with the stock filters or you may find K&N not so cheap in the long run. For a given surface area there is only one way that an air filter can pass more air.

heres one for you guys
Hey guys,
Forget about power, economy, which filter is cheaper or any of that. In this guys situation he should consider a much more important decision.
Series two discoverys and later P38 Range Rovers have a highly sensitive bosch mass air flow measuring device only inches down the air intake tube from the airbox, a K&N air filter uses an oil type stuff to help filter the air, hmm...
...save yourself a big expense, about $1000, when the service engine soon light comes on because the oil has contaminated the mass air flow sensor.
Stick with the factory paper filter(it's cheaper), make sure the filter box lid is on correctly(tabs lined up and not bent through the filter seal) and change it regularily!!
<edit> I guess I missed the part where he said series ONE discovery!!! :shock: :shock: DOHHHH!! </edit>
Later,
Don MacDonald
