I'm still waiting for a high-performance air filter to replace the stock filter (not sure if I want to cut up the airbox to fit the K&N RE-810). Comptech now advertises a foam element air filter for $69.95. Anybody using it?

 

I am using it. Seemed (subjective opinion) to improve throttle response. Fits perfectly, is oiled foam, and is washable.

I do not know any facts about filter rates or airflow.

honda_s2k, how much was the replacement cover?

I did the same thing and have always intended to replace the cover when a decent filter was available. Technically, I'm in violation in A Stock Solo II, but I don't think anyone's going to care (unless maybe I beat Gary Thomason! Yeah, fat chance!).

 

Hi Tom,

Check out this link:
http://www.hondaautomotiveparts.com/home.htm

Select Honda Automotive Parts, drill down with the S2000 info, and select the part category for "Air Filter".

You will find the following price information:

The discounted price is $49.48. It lists for $65.98. The K&N was a moderately expensive experiment in any case!

Before I bought the K&N filter I was considering a foam filter(PiperCross).
I asked a racecar builder friend of mine about it. He said foam filers are great for racecars but they don't filter enough for street cars.
Like cdelena I am no expert I just know who is. I like the one Luis has I think its called a JR?

 

I knew foam filters have been used for a long time in competition, but often pretty well exposed and not oiled. I justified to myself that this one would be adequate since it is in the box and oiled, so given the good rep that Comptech has I went with it.

I would not be surprised that oiled cloth is a more effective filter, but what is the best balance between filtration and air flow?

 

An oiled foam element filters fine, the problem would be the acceptable service interval. The pleated paper elements have at least ten times the surface area so the amount of acceptable dirt that can reside on the foam filter before it would be considered "dirty" will creep up on you faster. Another common problem with oiled foam elements is getting the right amount of oil spread out nice and even. Too much and you may as well use a stinky sock, not enough or uneven application and the filters effectivity is significantly reduced.

You make the call

 

Thanks RT, good info. Sounds like the service cycle is a bit more work.. I have let K&N

 

We will have available end of January a replacement filter with these characteristics;
Used only by a few top teams so far,this new air filter features a polyester cartridge whose filling is made up by yarns calibrated in microns.
This kind of fabric allows air to freely flow while guaranteeing an excellent filtering power thanks to its top-quality electrostatics characteristics.As a matter of fact flow resistance caused by the Filter
is reduced almost to zero while engine protection is totally guaranteed.
The results obtained in the competitive world so far,have clearly confirmed the absolute excellence of this new product in comparison with any other kind of filter materials both in terms of air permeability and of filtering power.
And this is a double performances difficult to obtain with the existing filter materials-both in oil-filled cotton and in sponge-which offer either air permeability or good filtering power and... it's almost always up to the engine to"bear the brunt"of this inconvinience.
This filter is a 100% dry filter,no oil aditive is used.
It will cost approx.$75.00
