| Post subject: | air filters? |
I'm about to prove how little I know about vehicles but here goes. I want to put a K&N air filter in my Jeep since they are sold everywhere, and seem to have a good bit of reputation. I know K&N makes 2 products, a air filter, and something called a FIPK. I don't know what that is, but I am assuming its expensive, and requires a lot of work to install it, so I am going with the regular K&N filter. Ready for the stupid question? How do I replace the air filter in my Jeep? Is it as simple as opening that big plastic box in the front, taking the old one out, and putting a new one in? Also, on a side note, a piece of plastic seems to have broke off. Best I can describe it is under the hood, where where it leads into the air filter box, a piece that seems to just bolt on and is not connected to anything else has cracked off... I'm sure its not essential but... can I get a new one cheap? |

Changing airfilter: open hood, locate big box on passenger side, open box, remove old filter, insert new filter, close box. Make sure to put that K&N sticker on the box to let crappy mechanics know not to throw out your filter. It's happened to me once before when they were doing a "courtesy" inspection. They threw out my K&N then charged me for a new filter

Yikes! So... they come with stickers! Sweet!! So K&N filters don't need to be changed? How much can I expect to spend on this anyways? |

You'll need to clean the K&N filter - the store that sells the filter should sell the cleaning supplies too. As for price, hope on to Summit's website. That'll give you a ballpark price range for both the filter and the cleaning supplies. If for some reason your filter is missing the stickers, just go to K&N's website and send customer service an email saying the stickers were missing. They'll send you some for free. Just put the one that looks like a stop sign on the box - it says something like "STOP this is not a disposable filter" (or something of that sort) |

I would go with a Fram before the K&N, use an Amsoil one much better with the K&N you have to take them out and clean them every so many thousand miles as well if you didn't know that, plus the oil you use in them sometimes causes problems down stream |

You forgot to close the hood!!!      
I think I paid a little over $40 for mine. |

Jegs is selling the one for my jeep for about $50, so I can probably expect $65-$70 where I live. Would a K&N, or a Fram, or whatever be much better than the stock disposable ones that get changed when I get my oil done? Are they really worth the cost? |

Whoops! That's why it's so hard to see sometimes! As for the airfilter - I like my K&N. Why should I keep paying for disposable ones, when I can save money and clean mine and continue using it! |

I must say, I do LIKE the idea of a washable air filter. It could mean less money down the road (not buying air filters) and also is better for the environment (less filters being trashed). Fram seems to make a washable too, any difference? |

Disposables are: 1. Cheap (money-wsie) 2. Easy to replace 3. A headache if you just don't feel like driving to the auto store and you keep forgetting to stop by the auto store when you drive by one 4. I haven't noticed much difference in my KJ with the K&N - since I have one now, I will keep it for at least a couple years. 5. Increase waste in materials and landfills |

I say a HUGE no to any air filter that uses oil to do the filtering. They claim you'll see like 4 extra horsepower at 5000+ RPM or something like that, but do you drive at the redline all day? Is that extra power worth the fact that you'll be letting in more dust and fine sand into your engine? Because lets' face it - the K&N style filters use larger holes to allow for better airflow and then rely on the wet oil to trap the dirt. K&N has cause problems with vehicle electronics when the air filters are over oiled (the engine sucks up the oil and coats sensors causing them to malfunction). And while this isn't a huge problem on the KJ or KK - it's still worth noting. I'm not saying that you should head my advice and avoid K&N filters like the plauge. It's your car and you can do what you want with it. But do so with the knowledge that K&N means worse filtration. Filters I like: Wix Mopar Amsoil (even though I haven't run one yet) |

Might want to look at AEM's DryFlow synthetic filters,filters much better then K&N,use no messy oil,and are washable and reuseable.They cost about the same price as K&N's also.

According to AEM's website, the ONLY product they make for the 02 liberty is a cold air intake... and thats $280us I checked at a place here and they can get the K&N for $60+tax, I'm gonna check at another place on the way home though.

Since I'm looking at the K&N air filters, I have to ask. Are the K&N oil filters any good? Would it be worth it to get one of them next time I go for a oil change? |

ive heard about the oil from the k&n type air filters in some makes messing with the mass air flow dont know about jeep though ..... i run an amsoil air filter think is was about 30 bucks from what im told you just blow out the dirt with an air hose and reinstall no oil to mess with ...... I dont know about production cars but back in the day our dirt track car ran a k&n for like 10 laps and we threw it away got so clogged it actually slowed the car down i guess with that messy of an application though the disposables are the way to go ....... |

Had the K&N, got rid of it and picked up an Amsoil Eaa201 (?). Cheaper than the K&N, feels stronger going up steep hills, no hesitation under acceleration like I had with the K&N and the stock filter. No need to oil the filter, the Amsoil is a dry filter so no chance of getting oil in the air intake and messing with the air sensors. Years ago (in 1989) I had an 89 5.0 Mustang with a K&N, the oil from the K&N messed up the mass air flow system. The Mustang got an Amsoil air filter after that. I forgot about that when I picked up the K&N and changed to the Amsoil when I remembered the expensive mess with the Mustang. K&N may make a great filter for specific applications, but with my personal experience I prefer the Amsoil air filters. |
