K&N air filters are one of the best ways to improve the efficiency and combustion inside the engine block. Think about this...The more air in the cylinder, the better ignition and complete combustion...The more power per detonation in each cylinder. Do you know what nitrous oxide is ?? Well, it is 03, which is an extra molecule of oxygen than 02. So, that oxygen is what gives the engine its power. As far as dirt entering your engine is concerned, I have used K&N air filters on all of my dirt bikes and every 4X4 truck I have owned. Never had a failure or any evidence of wear from offroad racing and hard riding, and I give the credit to K&N for protecting my engines while supplying a free flow of air at the same time. I fail to see how a street driven Honda could possibly be harmed by using a far superior product over a restrictive and inefficient one. Maybe consider having your fuel injection computer re-mapped to work in tandem with the increased air inducted by the K&N. This a common issue with this and other upgrades...headers, cat-back systems, superchargers, etc.

 

K&N has done test over and over. I have used K&N on ALL my CAI never had a issue. As for the guy who wanted to see the inside of a engine that used a K&N filter it's whole life up until I pulled the engine from my swap. Has 220k and every mile of that engine was used with a K&N filter. I can post pics if you like. The amount of dust that will get sucked into your engine is so small that is would be IMPOSABLE for it to scar your cyl walls or clog up your intake manifold. As for my K&N filter....I NEVER oiled them. I clean mine with a little bit of gas let dry and she is good to go.

Let me know if you want pics I can sure take them to show you what a K&N filtered f22a engine with 220k looks like on the inside.

*EDIT* as a matter of fact. If you look in the "sights and sounds" are of the forum and find my build thread "ryan's g22 vattac build" you will see pics of my old engines insides.

 

This is all very impressive and a good sales pitch for K&N I have to admit. I doubt however, the Honda dealership would tear into the computer programming just to accommodate a different type air filter. My car runs great now, so I just look at it as "If it ain't broke....!"

 

The $64 question not asked here should be "If K&N filters are the best and superior to a properly-designed filter doing the job of filtering it is supposed to do, why don't all car manufacturers put them on the cars at the factory as standard equipment?"

 

honda allows you to use a K&N drop in filter or even a full intake without voiding any warranty(they also let you change your muffler too). Also with just a intake or drop in filter your computer will automatically readjust your air fuel ratio. That’s the whole point of having oxygen, mass air flow and manifold absolute pressure sensors. They all work together so the ecu can compensate for extra air changes in altitude ect. ect. ect.

It must not be a sales pitch when K&N is the leading filter brand for aftermarket filters.

B/c it's a performance upgrade. Honda won't make any money off the deal. Also so manufactures do use K&N intake systems (includes the filter) on some of their performance car. GM use to do it on the GTP back when my dad worked for them. Toyota uses them on Supras. So like I said it's a upgrade from stock. To keep K&N on shelf at a dealership would cost too much. B/c K&N prob. won't be breaking much of a deal on filters since they can sell them in store for much more.

 

I really don't understand why you're so hostile 06V6ACCD.

You imply that they're an evil company but their actions speak contrary to such a claim.

1. If they're so evil, why have they been around so long? Were they on a bailout?
2. How exactly do K&N filters qualify as a gimmick on the same vein as the Tornado Fuel Saver or Electrical System Fuel Savers? Keep in mind this is a company with decades worth of long-standing experience in the automotive industry, not a fly-by-night shack.
3. Why are they offering to argue on behalf of consumers and recoup the expenses consumers were forced to pay when dealers blamed K&N products?
4. Why are they running multiple tests but most importantly, why isn't anybody else running tests to contradict K&N claims? Oh that's right, the dealerships blamed K&N and then admitted they didn't even have the equipment to test the devices they claimed were ruined by K&N.

A company that doesn't give a damn will not run multiple tests to save their product in the public opinion nor would they offer to test 100+ MAF sensors and argue on behalf of consumers, that's called solid customer service.

Your statement that they lie about test results is overly malicious and has no place in a reasonable discussion. There's just no way to argue with that kind of statement. Even if K&N doctored test results there's no reason to argue since the dealerships don't even have the equipment to test the parts or K&N filters and they never will. Maybe they should buy some and contradict K&N.

The truth: Your engine was better after removing the K&N filter. I'm going to assume you're not lying because you have no reason to. But you have no idea why the K&N filter was incompatible with your system, all you have is a hunch. You could have underoiled or overoiled and that's not the fault of K&N nor is it the fault of their filter.

By the way I'm not using K&N right now, I'm using a generic paper filter. I have no idea why you think I'm trying to deliver a sales pitch for them, I have no stake in K&N.

 

You have to realize that Honda designs their intakes and all other parts to appease the masses. They're made to be easy and smooth to drive and comfortable for as many people as possible. The intake is made to be nice and quiet so it minimizes cabin noise and doesn't have performance in mind, end of story. You cannot tell me that Honda designed the Accord as a performance machine, even the V6. It's a commuter car. All cars are becoming sportier nowadays, but your '06 V6 is not a muscle car simply because it has a V6 in it, it's still a grocery getter with a bit more pep

In the end it sounds like you're against any sort of intake so people should just drop that whole topic and start recommending other small performance upgrades. I would still like to hear your opinion on a clutch and flywheel upgrade.

Everyone, please, let's drop the K&N argument. He's clearly either a troll or incredibly thick skulled, and either way he will not be swayed.

 

How do you change the filter on a CAI? Do you have to remove the bottom splash shield? Doing this, plus having to clean the filter and re-oil it, plus the risk of hydro-locking your engine if you happen to drive through a foot of water. It just seems to me, the added hp (maybe 5hp) is not worth the risk, cost, or the trouble of adding a CAI. I think most people buy a CAI just for the sound it makes. I think silence is golden.

 

They make water shields and socks for CAI filters to avoid hydrolocking, as well as bypass valves, so that shouldn't be a worry unless you're going to be somehow crossing raging rivers in your Accord. I live in the Northwest, and I know guys who are running their CAIs and SRIs all day without socks or bypass valves through the giant puddles out here and they never have issues. If you submerge your filter that's a different story, and if you're worried about that just get an SRI rather than a CAI. Mine has been running perfectly fine, rain or shine. Never hydrolocked when it was raining all day every day and now that it's 80-95 out I don't have any heat soak issues even when sitting in stop-and-go traffic on I-5 for two hours.

The filters are easy to remove, and a majority of the good quality ones (K&N) are washable and have lifetime warranties. It's as simple as unbolting the tube from its mount (unless you have enough clearance between the tube and the front of the engine, if so skip that step), loosening the hose clamp that holds the filter to the end of the CAI and pulling it off. Just about as easy as changing the stock one, once you've done it once it's a breeze.

To each his own, if you like the quietness of stock don't get an intake. There is a legitimate reason for wanting additional airflow in your engine, it's not just about the sound, as awesome as it may be.

 

This whole thread is getting uglier by each additional post. No, I do not use a K&N in my 1993 LX. It is a basic transportation car only, and not worth the investment in my opinion...This car has 226K on it and adding more HP isn't a necessary upgrade. I prefer to leave it stock as it runs perfect...like a Seiko Dive Watch. My posts to validate the K&N air filter remain based on years of personal experience with their product...A LIFETIME warranteed, free flow air filter. I can't speak of your misfortune with your application, only my own great satisfaction with an outstanding, reputable company and their excellent product. End of story...
