This makes me wonder about all the high performance air filters out there. I remember a test being done with the old HKS mushroom and it made terrible power, but I wonder what the filtration rates actually are.
In my time at WSRD, we always used UNI air filters, which are an oiled foam.
I'd gladly sacrifice a few horsepower for clean air on my expensive projects.

And by "years and years" you mean a couple passes at the strip and a few thousand miles. I've never seen a daily driver without a filter last for very long (or be driven that much), usually because they're power hungry or they have a garbage tune and grenade the thing.
Forward facing turbo kits are
very popular in the 4G63 community, and I
have seen turbo compressor wheels chipped, scratched, and worn from foreign debris. Funny, those engines didn't have very good leakdown...
