With the growing number of drop-ins that are popping up on the market I was wondering what others were running and which one people thought were the best. I have a K&N in my truck, didn't add any noticalbe power, but it did give me a mile or two more per gallon on gas. The reason I bought it cause it was cheaper to buy one filter once, rather then several every 3 months or so. Plus it was only 50 bucks.

I've seen ones like Fram's Air Hog, Cool Blue, Air Raid, and other ones. So I was wondering what every one was running in the cars and how much it cost, also any notiable power increase or fuel economy.
 
there was a test by soem magazine couple years back and Apexi filters flowed and filtered the best out of HKS,K&N and others.
 
I have a k&N, it only cost me about 50 bucks Cnd, and no real power gain, just added to my already good gas mileage. good spark plugs are good for that too (iridium (sp?) ) 👍

Whaaat.. Apex' filter might have flowed better on a certain application/vehicle, but K&N has and will be the best flow/filtering unit around. HKS' SS used to be really close but it was made out of foam and would eventually break up in to small pieces = not good.

And the prices that aftermarket manufacturers like Apex'i / GReddy/ HKS charge for an air filter 'kit', I can buy 4 K&N's.

I use a K&N cone filter. :)
 
The new-model A'PEXi filters are superior to the K&N design. They have a central channel, which is engineered to eliminate turbulence in the intake, improving flow. Additionally, the A'PEXi also provided better air filtering. The A'PEXi also uses a dry design, as opposed to the oil system of the K&N.
 
The K&N has been proven in every single form of motorsport there is. There is a reason 3/4 of the people in this world use it. If Apex claims to have a better product, surely they have proof of higher hp/tq gains over a wide margin of applications.. Or don't they?

I know one thing they do have to offer, a lot of bull****. After looking at their site and seeing them claim they made 8.5whp from a grounding kit, I had to laugh.

Some people will buy anything. :lol:
 
The benefits over a 'normal filter' are less restriction and longevity (mpg I don't pay attention to). For people whose vehicle(s) will never see the track or don't make d!ck for power, a Fram filter will be more than enough.
 
You're wasting your time if you're looking for any significant gain in performance with any drop-in air filter. Drop-in's are a waste of money just like CAI's - they cost a lot, and offer little in return. If you're looking for a decent gain in performance try out the K&N FIPK. Believe it or not, but 90% of guys over at SVTPerformance prefer it over any CAI kit. I've seen people regularly post gains of 20+rwhp on their '03/'04 Cobra's with just the K&N FIPK.

I myself run(or ran, now that it's my Dad's car) an S&B Powerstack intake. Here's a picture:

It's basically just a 9" cone filter attatched just before the MAF. You just remove the restrictive factory airbox, mount up the bracket for the S&B, and attach it. I ran an Injen CAI on the S2000 - no SOTP difference, but it definitely made it scream louder under WOT.


And, uhh, only people who drive slow underpowered cars care about gas mileage.:lol: 👎
 
I really want to get a Volant Air box kit either that or a AEM Brute Force, since for the S trucks a AEM is the best intake set up you can buy. Gives you a ton of power for a couple hunderd bucks, somethign like 9-10 and Truckin did a dyno test showing that you could gain that much power with it. I really need to get it.

I remember K&N filtered the worst there was a lot of dirt after testing and was far behind in flow but this test was way back. K&N might of changed designs by now I know Greddy changed after the article was released. I used a K&N filter in my integra tossed it after 3 years the filter turned into this black purple brown like color.

'Tis the reson they sell cleaning kits for them.:p The things will perform, and last, forever considering you maintain them properly.
 
I ran K&N drop-ins in both Neons and the 'van. I found no SOTP power increase, but they did notably improve throttle response, and they're easy to take care of.

I've since switched to cone/tube CAI setups on the Neons (way down low on mine, shortened/raised on my wife's) and they made SOTP improvements in power - particularly in conjunction with other mods, like a Mopar Performance PCM. I've run the car with and without the intake on the stock PCM, and also with and without the upgraded PCM on the intake, and having both the PCM and CAI working together made by far the biggest difference.
 
The results I mentioned are from an independent test. I think it was done by an aussie Skyline site, don't remember what, I just got the link off of Zilvia.net.
