Need large diameter tunnel ram air filter.

[jdmawd]

Im looking for a large diameter tunnel ram air filter that will not rust from being exposed to rain and moisture or simply fall apart during installation.

I have had 3 different seemingly cheap filter on this car. Both have either, As described above. Either fallen apart or simple rusted out.
Im interested in a filter that's at least 7" in diameter and 5-7" long with a 3" inlet. Preferably with a tunnel ram top.

I found one prospect using a google search. That looks ok, if anyone has used these filters please chime in. In regard to quality or simply you're experience using this filter. Or any other filter that comes close to what im looking for.

here is what i have found so far

Have you tried K+N yet? I know there is another company out there that would describe exactually what you are looking for. They have a SS mesh so it won't rust and it is very durable. Sorry, I don't remember the name though.
