I've got our 06 Duramax with the cone filter just like the K & N filters, no
problems showing up in the turbo intake tube or our Oil reports in 50,000
miles. I've never felt anything in the pickup tube on ours and I feel up
there every time we pull the filter to clean it, and we live on rural roads up
here all dirt so the filter does get dirty.
