Been asked many times before, going to switch back to airbox, with so many filters around, which is the best one?

 

There a few good ones. I haven't tested to determine whether there's a difference between them, but from personal experience, K&N and Green work great, filter effectively, don't deposit their filter medium in the induction tract, and are washable/long-life. Cosworth reputedly good but apparently designed to be replaced at the same intervals as a standard paper filter, to the best of my knowledge.

If someone pops up later telling you about some filter group test in a magazine a month or two back, I would not place too much trust in the test results, and wouldn't buy the "winner".

 

I run a KnN, zero problems

 

Cool, will probably go for one of those, also, I think my MAF was scaled to accept the induction kit, can it be re-adjusted back for the airbox?
Also, I'm guessing I would have to keep it off boost if I changed back, until it was mapped again
Thanks

 

I remember reading in a Jap magazine recently that the Do Luck panel filter was the best and you can get them through Sumo Power

 

You can find Splitpin @ Online Psychic.com

 

Would k and n be a good choice?

 

Yes.

 

I used a K&N panel filter for 5 years on my old MY 00 Classic with no problems.

 

cool, will order one tomorrow, thanks guys

p.s, do you ever have to clean them?

 

I don't see why?

The tests were done on a newage impreza and looked a pretty comprehensive test

 

Well lets say that if the intercooler isnt cooled properly then you will suffer heat soak, so if the "winner" is the first one on thats probably why

just put my green panel filter back on after having a hks induction kit on for six months or so,its so much better and not as annoying lol

 

Another vote for k & n,been using these for over 20 yrs,never had no problems to date.

 

Reading the various summaries of the article on here, the test methodology appears to be unpublished, and therefore subject to a number of influencing factors, while the results are totally incomparable with any other data I'm aware of. I also asked (sarcastically) whether there was an advert for the maker/distributor on the page facing the test, only to be told that there actually was. Which raises some level of suspicion about the results.

In addition, my understanding is that the "winning" filter is an oiled synthetic foam construction. I would personally not use a filter of that type in a car I had anything to do with.

Not at all the impression I got. A comprehensive test would involve, for example, mentioning (and negating) any environmental changes that may skew the results, siting pressure sensors before and after the filter to determine pressure drop (and therefore go some way to explaining why power increases are generated, tests of filtration efficiency both in the short term and over the life of the filter, and fluid medium loss. Were any of these actually conducted?

 

ordered a K and N in preperation of going back to the airbox
