    Default 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 .

    Default K&N filter servicing-don't forget!

    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.

    Wink k&n filters

    I have one currently installed in my 94 D-90 (#287 of 1943), and have noticed a nice improvement in HP as well as mileage. Yes, cleaning the filter is very important, good point Mike.

    I rarely clean mine. The dirtier mine gets the better the filtration is what I have found. I have not noticed any reduction in power with a dirty K&N. I clean it about twice a year.

    Good call, yes leaving more 'collected dirt' does add to filtration effects. I do the same with my Audi //S6. This has the turbocharged 20v 5cyl and in some instances TOO much K&N oil is a bad thing = ruined hot wire MAF sensors. Just go easy when cleaning and re-oiling, it only needs a little bit.

    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.
