    I don't know anything about the Tornado.. If anyone does, please start a seperate topic. This way, we can keep this thread about the K&N. Anyone interested in Tornado information would probably not think to come here...

    Does anyone know why they don't make a K&N system for the northstar?

    Caddys are still not thought of as Hot Rods, thats my guess

    Welcome to MY world! Trying to hot rod a Caddy is looked at by the performance industry as total loonacy(probably mis-spelled).
    I've been dealing with parts stores and aftermarket manufacturers telling me there aren't anything available for my car for years. Luckily for me, it happens to have the same drivetrain as an Impala SS so most things can be swapped onto my car. But still, you're right, Cadillacs aren't thought of as a car that someone would ever hotrod.

    you're lucky I wish I could find out what shares parts with a 77 fleetwood.

    I was thinking about getting a KN filter, and putting in a cold air intake like this: http://discussions.gmforums.com/show...light=cold+air

    Do you think that it would be more worthwhile to do that (it doesnt sound hard), or to put a cone filter in? On paper, that method looks better, because witha cone filter you are going to suck in hot air from the engine compartment, and the airbox helps rid this.

    Wes,
    Your sig says 95 Fleetwood, if that's the car you're considering doing this to, go out and get a K&N Fuel Injection Performance Kit for a Impala SS. It bolts right into our cars. If you want to see it installed, go to my site at CarDomain and see the pics.

    sorry to say, i dont believe in the K&N. in some applications they work just as good as paper.

    proven again and again in tests, some stock paper filters flow better.

    if your going to use one, get an oil analysis done!!!

    in most cases, the K&N doesnt filter as well, leaving you with a high Si(silicon) count.... not good
    so i woud run one for 3k miles, get oil analysis to see whats going on. i still say the paper will out filter it. more flow = more dirt...its no myth

    I'm not sure what tests you've been reading but the dyno tests I've seen indicate that the K&N filters (and many others) do outperform the stock paper filters. As for filtering capability, it only makes sense that when you increase flow, you're doing so by decreasing restriction. This is done by increasing the size of the passages in the filter, which in turn will certainly increase the likelihood of particulate ingestion by the engine. Of course if you want to increase flow WITHOUT the danger of sucking extra stuff into the engine, you COULD increase the the filter size. Overall, the full-size K&N cone filter does have an increased filter area and if you use the oil properly, the flitration SHOULD be only minimally less than with a stock filter, if at all.

    yes but... a direct replacement panel will not filter as effectively as a stock paper.

    it is more common on german cars, the paper flows better than K&N but I think an LS1 forum did the test, and it flowed no better than stock. I have read many other similar reports. When i put a K&N filter on my old 1985 eldorado, it ran like crap. a stock delco i put back on made it run like it used to.

    Well, if it only increases HP maybe 1 or 2 and you can get filter oil and other crap in there, then i may just stay with stock paper. Are there any other high flow filters that do not require oiling?

    I have heard about those, do those work better than KN and do not require oiling?

    Amsoil Air Filters

    I like these better than K&N but I don't really know if they have all the same stlye filters as K&N, I sure they do though

    Oiled filters I think are the best. Some swear by Oil Bath filters

    most all High performance are oiled. Oil makes up for the flitering you loose with flow. and flow is what makes HP

    there are lots of manufactures that are getting into this technology, like Accel, Barry Grant, Holley, and about every one who makes cold air induction kits
