I was changing the oil for the first time on my buddys swapped ZC and when I went to change the filter I noticed the on on there was alot bigger than the standard Honda filter. Does anyone know what filter will work or where I can find one that will fit?

 

It's the old style filter before they switched to the shitty smaller ones to save money. You can use the civic filter but I reccomend using the s2000 filter. The s2000 and Insight are the only cars that get the better old style filter now and it is the same one as the one you took off.

 

use and 89 integra filter

 

Honda only makes 2 filters for their 4 cylinder engines, and I just explained them both. They might even be the same for the V6's but I'm not sure.

 

Why is a bigger filter so much better?

 

More surface area on the filter media; so, it takes longer for the filter to clog to the point that its bypass valve opens allowing unfiltered oil to circulate back to the engine.
