Review on 33 5074 Replacement Air Filter by James Lighting

I held the K&N air filter up to the light and looked through the tiny holes throughout the filter. If so, how does it filter contaminants out of the engine? This should allow for better airflow as there are tiny holes in the filter. I'm sticking with a synthetic-filled NAPA Gold air filter for engine protection. A few folds were folded right out of the box. I'm not impressed with the quality of the air filter so a return is in the works. I would have expected more from a K&N product.
