Thought I'd post here as well:

As a curosity, if you have a K&N installed, how long has it been in your car?

Sorry, I don't need a filter as far as I know but maybe you can tell me how I get to the air filter on the '97? No mention in the manual. Thanks.

Remove the battery vent that is on the right hand side, it has snap fittings.
Remove the 10mm bolt holding the air snorkel and slide the air snorkel out.
Un-clip the the release tabs around the air filter and that's it.

If they don't nail you for a return, I still have it. Mike's been encouraging me to put it back in BTW.

Iv had a cone style K&N for while now, maybe 20-25 K miles or so.

I'd had a K&N drop in filter in another car for about 90K. Unfortunately, I didn't tear that engine down to see how the internals were nor did I get an oil sample. My suspicions are that my main problem was oil flow and to some contributing point the grit allowed over the years. All theory though, that is one part why I removed it from my LS.

When i first saw the K&N filter, i thought that it may have let fine grit get through. I just clean are recharge mine more offten. What problems did you have with your LS?

No problems that are obvious. The oil analysis indicted universal averages of 11 PPM but mine tested 16 PPM when it came to silicon. This component is present in sand catsed parts, gaskets, anti-freeze inhibitors and dirt passing through the air filter. Since there was no obvious signs of anti-freeze in the oil, this leaves the gaskets, parts and air filter.

This test I used the K&N for the period. My next sample will be from the stock filter. If the silicon PPM result is lower, I will have a strong suspicion that the K&N does allow finer dirt particles to pass. My car has 82K so it will take additional tests to bare some speculations that I have.
