    Throtle Monkey Or Soccer Mom, it just doesn't matter..

    First of all..I'm not someone who just readily believes anything that's been read/posted on the internet - With that said, it really doesn't matter if you're a throttle monkey or a soccer mom, or even just a regular good ol "point a to point b" driver/commuter - If you're a throttle monkey like me that likes response you'll simply love K & N air filters even more. After having used just about every brand out there I'll boldly make this statement > K&N Air Filters Are The Best!

    Some time ago when I was first told about K&N filters and their positive affects on throttle response, gas mileage, and horsepower I really thought the guys at this particular shop must have been getting paid to rant about them. My first direct experience with them would soon change that. After purchasing my first fresh off the line triple black convertible Cobra in the summer of 1998 I was a bit disappointed with the throttle response, I asked how could a car with over 300RWHP be so sluggish (slow to respond) to the throttle being pushed to the floor? I thought I'd purchased a Cobra, where's the striking power?

    After approaching the motorsports shop about this and hearing the same rant about K&N repeated in such a manner I decided to try one. There was an immediate and quite notable increase in throttle response and power. The following weeks of use also showed an increase in the gas consumption efficiency // Can I get a +3

    Lets get down to the nitty gritty if you will

    Availability: You might ask, do they have one for MY car?
    K&N has been at this a while so they've likely got a model that will fit your vehicle. And if you're already curious right now, you can search directly here:
    https://www.knfilters.com/search/appsearch.aspx
    They are widely available at the local AutoZone, or online at autozone.com

    Price: Does it matter if the product really does what its touted to do? Price should not be your primary focus if you want something that really does what it says it will. Some would argue that they're too expensive. I've found that overall they're about the same price as others and for some models of cars less than the competitors. But what is it they say? Mileage may vary..

    Quality: Quality is good, and more importantly.. "consistently good" in both the individual air filters (drop ins) and the full kits (Air intake pipe/box/filer). There is some clearly precision manufacturing involved here. Uniform folds in the filters, and quality build of box and pipe assemblies. No jagged edges, and doesn’t look like it was pulled out of a sloppy moulding.

    Finish: I guess this could fit in with the overall quality but I'll just illustrate a bit more instead. They look great! The stock filter/pipe/box may function, but it doesn't function as well as a K&N, and I'd bee willing to bet that it doesn't look as good either.

    Easy Peasy? Ease of installation much? The installation doesn't take long and can be approached as DIY. Installation was very straight forward, actually took a larger portion of the overall "installation" time un-installing the stock pieces. Everything fit into place easily, everything lined up and there wasn't any need for re-boring any of the holes, or reshaping anything on any part of the assembly.

    If you've at all considered purchasing a K&N replacement for your car hopefully this information is helpful in finalizing your decision to purchase. Oh, and just one more thing.. I'm a real believer, purchaser, and user in K&N products .. and I don't get paid to rant about them. It's just hard to not get excited about something that actually works like it should, and then some!

    Pros: Have never NOT had an increase in throttle response, milage, and horsepower on any vehicle I've installed these on.

    Cons: None really if you're realistica about things. The only thing some would argue is that they're more expensive.

    Works as expected, BUT...

    1 of 1 people found this helpful

    These perform as expected; however, you will have to check/clean your MASS AIRFLOW SENSOR at regular intervals. If you don't know what or where that is, then either find out or don't buy this or any other oiled air filter. I've owned three of these in three different vehicles and the MAF was regularly clogged up with the oil from the filter. I would check/clean my MAF every 5000 miles. If you don't, then your car will run very poorly or not at all if the Mass Airflow Sensor gets dirty enough.

    If you're up to the additional maintenance, then go for it! These are very good filters!

    Pros: Increased airflow, you only need to buy one, EVER, vehicle appears to have more "giddyup"

    Cons: The oil in the filter WILL clog up your MAF on fuel injected engines

    Night and Day

    Just bought a used F-150, the air filter was disgusting. Put in the K&N and I could feel the difference in power right away. 2nd time using these filters and it's impressive the difference you can make with just an air filter.

    I am a K&N fan. I have always used K&N air filters. They always work as advertised and this one is no exception. Air flow is critical to your engine's performance why wouldn't you want to increase and filter it better?.

    Pros: Better air flow, increased gas mileage, washable
