K & N Filters

Just fitted a new K & N filter to my 95 Def 90, BIG improvement.
Thought you all would like to know.

Yes, when I fitted the K&N replacement filter to my '94 Defender 90 NAS I removed the clipped on trumpet air intake and noticed a huge improvement in throttle response on all rmps. Very nice. Petrol mpgs improved a bit as well. The biggest test was pulling a 1,280lb pop-up camper and fully laden up the backside of Hwy 70 over and past Vail, CO. Worked like a champ .

Great!! Good to hear that others have had such a positive improvement by fitting an easy performance enhancement. Keep Rovering!!

K&N filters are great, but don't forget to service them(and let them dry afterwards as to not mess with your V8 EFI airflow sensor).

The Rovers North part number for the service kit is: RNF145

you can wash them in hot water, then use compressed air to dry them..

Looking at the K&N website FAQ(http://www.knfilters.com/faq.htm), using compressed air to dry the filter is not recommended, neither is running one without oiling it first.

Advice: keep a paper filter to use in dusty conditions. K&N filters are great for some added performance in clear air environments but at a cost to the filtering ability needed in harsh conditions. I found this to my cost.

K&N was designed for track use. If you're on pavement, with a carburetor, it'd be a good way to go. If you're in dusty conditions, or using a vehicle with a hot-wire MAF, it may have unintended negative effects.


Just be educated about the give and take of any changes you may contemplate.

I've had the same concerns. 'might be fine for the city folks, but you should see the stuff I shake out of my air filter in the summer, from all the driving on dusty unpaved roads that I do. I've always been leery of "free flowing" air filters as a result. Engineering-wise, there's no free lunch; if the filter lets more air through, it's either got to be alot bigger, or let more dust through as well.

I have to agree , seems like saying "huge improvement" from an air filter should imply better filtration. when in fact it meant less....
