Hi all,

New to the S2000 world, I was messing around under the hood and wanted to know whether I have the OEM filter in there or an aftermarket, only asking because I saw traces of oil at the bottom of the pan. Also does it look like it requires changing? Car is a 2005 with 23K miles, so I am assuming it was never changed?

Cheers.

 

Yours looks generic. The ones I'm used to seeing are either green (2000-05, 17220-PCX-003) or blue (2006-09, 17220-PZX-003) filter material color.

 

Do you track the car?

Oil can slosh into the intake tube. Some of it will go into the intake manifold and then be burned in the engine. The excess will flow the other way and puke from the filter and end up in the airbox.

It looks like a regular OEM or OEM style filter.

 

Yours looks OEM and very old. I would change it. I recommend K&N, my car is 18 years and lows miles like yours.
Im on my 2nd K&N filter

 

I had a K&N for years and always seem to over oil it, so I got rid if it and went back to OEM.

 

I would recommend against a k&n filter. They don't trap contaminants to the same level as a good paper element. It'll allow more particles past, which will also contaminate oil. You'll have increased wear rates.

Undoubtedly, someone will chime it with, "I used k&n for X years and X miles and never had a problem.

I always laugh at the 'never had a problem' response. Don't they get that something that increases wear doesn't have any immediately observable symptoms?

Engine will die sooner, and start to degrade sooner. But it happens slowly, so you hardly notice. When it eventually dies, you have no way to know how much longer it would have lived of you didn't do things that caused increased wear rates.

If a k&n filter actually provided tangible benefits for its increased wear, it might be worth it. But the only benefits are reusable filter, a negligible increase in power, and sound. There are better ways to get enhanced intake sound.

 

I would use the factory filter.

The K&N's gain is going to be negligible, and they typically allow more contaminants in, as well as leaving a film of filter oil on the inside of the intake tract.

I like using reusable stuff too, to reduce waste. But...don't really think its worth it here. Hopefully, the OEM filters are effectively recyclable after disposal.

 

Original post's filter looks like this one.

 

I will go for the OEM, going to pick one up today. The one I have looks like the premium guard one for sure. I am missing the ring that holds the rubber 'hose' onto the filter housing, hope this will not be a problem.

I do not track the car, just need her back to spec. Sse currently has 23K miles on her, trying to find another that I can drive more frequently and modify (conservatively). this one I will save for later

 

I just took out, it was an OEM Honda filter after all, old, maybe weathered? The new one is a bit more greenish, surprising amount of oil under the filter. There was no steel ring holding the filter in place, but it was very snug none-the-less, so I do not think it needs it.

Appreciate your input folks.
