    K&N Filters - Do they change the \"felt\" HP?

    Do K&N air filters REALLY change the felt horsepower? I'd like to hear from those that have tried them. My suspicion is it's a marketing gimmick, but I'll listen to what you experienced guys have to say. It's in my nature to be suspicious!! Thanks!

    Re: K&N Filters - Do they change the \"felt\" HP?

    From what I've heard, a K&amp;N will boost HP in the high RPM range, which Blazers rarely see. I do know, however, that a few guys who run them around here SWEAR that they got about 2 MPG more after they installed the filter.

    I've always thought about putting one in the K5 but I can't stomach the $80 pricetag........

    Whether they do or not, just the fact that you never have to buy another filter is enough for me. Dyno tests have shown that they do increase the power, if you can feel it is another story.

    i like that you can clean it out and reuse it. you do get better mpg but the hp gain is like 2% if that.

    I could feel a slight difference in the low end. Some of my friends even said that it sounds louder with it, but I didn't hear a difference there. 80 bucks is way too high, Advance Auto has K&amp;N's for $35. It's well worth it IMO and it reuseable....

    I just put one in today, actually. Like one of the previous posts said, you can definitely feel it at higher RPM's. Generally, it added a little bit of old fashioned pep to the engine when it came to accelerating and passing. I can't vouch for the dyno results, but yes, I could "feel" a difference.

    Up here in the Great White North, performance accesories cost a lot more. It doesn't help that most of the stuff is made in the US, which kills us because of the exchange rate.....

    Yes! There was certainly more "vroom vroom" audible when I got on it. I thought it was just my imagination, running away with me...

    Re: K&N Filters - Do they change the \"felt\" HP?

    ehhh in my trucks I can't say I felt much difference that I wouldn't have felt with just a new air filter. My car yes I did notice an improvment.
    The ones in the trucks pay for themselves in about 8 months if you drive lots of dusty roads. I trail pretty regularly and 2-3 rides and the papers were clogged so bad the truck couldn't breath. I clean the K&amp;N's every 3-6 months and really don't notice a loss of performance between cleanings. It's been worth it just for that.

    It's not my damn planet monkey boy!

    Re: K&N Filters - Do they change the \"felt\" HP?

    When I installed mine a few years ago, it actually scared me the first time I stepped on it with the new filter. It was a lot louder. Sometimes I step on it just to hear that wonderful sound[​IMG]. It did make a difference in power too. I was able to get up and go a lot quicker. I installed the open element style so that may have been why it was so much louder. I actually have people look my way when I floor it. Then they laugh when they see my slow-a$$ Blazer making that awesome sound.LOL[​IMG]

    Re: K&N Filters - Do they change the \"felt\" HP?

    I definitly felt it when I put mine in. Part of had to do with the fact that my old air filter was probably more than a year old

    Re: K&N Filters - Do they change the

    well it's kinda funny because I got my exhaust done in my k5 before I added a K&amp;N (hooker super comp headers, no cats, true dual exhaust)...

    when I added my K&amp;N I noticed a HUGH difference... but then again you could take 10 k5's, do the same thing, and everyone would probably respond a little different...

    no also keep in mind I had the stock air filter, but it was not connected with the tube up by the front grill so I wasn't drawing cold air either...

    Re: K&N Filters - Do they change the

    can't answer your question directly but add it up it's well worth the investment to get one when you add up costs of replaceing air filters

    Had them on two trucks. Would buy again. No noticable increase in power.

    You don't feel HP anyway, you feel TORQUE. That's what slams you back in the seat. [​IMG]

    Re: K&N Filters - Do they change the

    I have had them on the past several vehicles I have owned...I did the Headers/Duals at the same time on my truck, so I can't say...I noticed a difference in the Vette, tho...just seemed to add some snap...the truck filter was $35 at Autozone (3"X12") fits right into the stock housing for State Inspections....the cleaning/reoiling kit is like another $10....I like 'em.....JD

    Stuck?...Hell no..I still got some gas left..

    I hear that Grim. When we went the the slab(real sandy/dusty) my filter was clean but when I got back I was amazed the truck was running it clogged up so much!

    Re: K&N Filters - Do they change the \"felt\" HP?

    NUff Said... Mostly positive comments and I do like the idea of not having to buy filters over and over again. Called NAPA and they're haveing one sent over for pickup tomorrow. Will post back to the group to let you know what I think. FWIW, Napa is asking $45. I get a 10% discount off that so I figure I'm close to what I'd pay mail order with shipping. Schucks was also $45 so I think that's the going rate locally.

    Thanks for the great response.

    To be happy with your motor you have to combine a lot of small horsepower gains to make a big one. K&amp;N isn't a night and day difference, but it did help. Do that with an ignition upgrade, exhaust, etc and then they start to complement each other and really boost power.

    Re: K&N Filters - Do they change the \"felt\" HP?

    Ok... totally my $.02 here but don't bother w/ one for a stock motor and I really don't think they are all that for a daily driver. I have one and it is actually gonna be pulled out and saved for my next street rod cause I'm way too sick of cleaning them. No real difference IMO.
