K&N drop in filter

[Brightred]

I have noticed people posting online at different web sites, some say they do get a horsepower kick from K&N drop in filter others say nothing at all. each group showing dyno charts. But when you think of it the filter lets in more air but that can only happen when the car is going fast [more air rushing in] So am I wrong to say you cannot test the filter on a dyno because the car is stationary not moving ?

Alright, I've researched the drop in filter market pretty heavily, and there hasn't been anything for me to say that the K&N is a worthwhile investment as far as horsepower goes. I also have a hard time believing that the power would come from air "rushing" into the box, so no you most likely wouldn't get any power there either. The K&N might be kind of valuable to someone who gets the car early, and wants to put the panel in to save from replacing the stock one every so often. In addition, some people show minor fuel savings as well, which hasn't really been totally proven to be true either. My gut tells me to stay away from the K&N filter for our cars, especially since their is a chance, albeit not a high one, that it could foul out your MAF sensor as well. Although I have not ordered the filter from AMSOIL, I feel as if their product is looking to be the best right now. For 25 bucks, you can't really beat the price, especially if their is some gains to be found. This is the filter I'm going to be buying soon, and letting people on here know about when I do finally get around to it.AMSOIL Ea Air Filters - Nanofiber Technology Most people have nothing but nice things to say about their filters, which is untrue for the K&N drop in filters.

You should leave the research to professionals. Its totally hard to believe that for all intents and purpose's air pump would benefit from higher air flow . Oh and it will not foul your MAF failing to clean it on recommended intervals will though.

And what professionals would that be exactly? All I'm saying is that the K&N hardly seems worth it if your looking for ponies, looking at what ordinary people have to say about it, and the dyno results that those people pay for, not everybody shows a gain with the K&N, so until you show me a dyno with gains for a 4G you've got nothing to say of value to me...

Well than go peruse the dyno queen thread; It doesn't take Masters to figure out a higher flowing air filter is better for power, and fuel economy. But hey stick to restrictive paper filters no one is forcing you to buy a K&N. Just don't say something stupid like there is no benefit from a proven product with years of reliability, results, and research behind it.

K&N Filter runs $45... Yes, you will get some benefits, 2HP? .5MPG? The design of the stock intake is what robs us of HP.

Take that money and put it towards a proven mod that works, Like a CAI system. Proven 12 to 15 HP depending on the system and GS vs GT.

"The car has to be moving forward to get additional air-flow...?"
Hell, the velocity of air being sucked in by the engine at WOT
exceeds 200MPH, our car only goes 135MPH .

From what I have researched and found and owned it depends on how the intake is set up on the car. I own a 90 CRX SI and Honda did everything possible to squeeze out enough numbers out of their motor so they found the best way to set up their intake (location etc). so when i was researching intakes everyone said that it would be a waste of money to get CAI due to heat soak in the engine bay wheras having the factory intake box and a k&N drop in filter, it keeps it from heat soak and still runs cold, so the BEST is K&N drop in filters for the CRX. For our cars it is a different story. We have a restrictive airbox so it is wise to get a CAI for both hp gains and gas mileage. Take that info for what it is worth and your decision will be made based on your budget and what you are looking to do.

Very true! Some OEM designed intakes are better and the K&N Filter is a good drop in. But my first mod for my GT was a K&N Filter , so money best spent on a CAI system for our car. I've learnt quickly not to cheep-out, if it takes an extra two-months to save for something you really want, then wait. Otherwise, six-months down the road you'll be changing out that cheep mod for the one you really wanted, so you'll end-up paying twice for the same mod!!

so true clov. i've owned a few cars that i have modded and my first two i was dissapointed by going the cheap route. I wasted more money trying to fix the problems i had due to aftermakret cheap parts then doing it right the first time.

save your money the best way you can to get the best quality parts that you know will work and won't give you a headache down the road. not saying k&n is a bad option, just better to go with the better, proven parts that work (injen) and won't waste money

Yeah, when I went out to buy my life long quest for a quality guitar, one that I would be playing for the rest of my life, it came down to two guitars, $1200 and $2000. I kept on looking both of them over and was leaning towards the $1200 guitar.

The sales person looked at me and said, John I'll give you a great deal on the $2000 guitar. I'll save you $1200. This peaked my interest!! He goes, John if you buy the $2000 guitar now, you won't be back six-months from now buying a second guitar, thereby saving yourself $1200 dollars.

Yeap, you guessed it, I save myself $1200 and bought the $2000 Seagull Artist, worth evey penny!!

If you were truly intelligent on engine management, then you'd understand that engines create pressure that sucks in air. The drop in air filter will not give you large gains because of the rest of the intake system design and temp of air coming in.With a drop in filter, you will not see a change in power whether you are moving or still because of the intake system. The reason why CAI systems work is because they relocate the filter where air will be forced in at cooler temps. This is simple engine management that people complicate. Oh, and the oil filters usually damage the MAF by the owner NOT maintaining it correctly and over oiling the filter. Which is not the filters fault.
