They're known to cause issues in 2nd Gen trucks. The MAF is so close to the filter that any extra oil can contaminate the MAF and cause various runability issues.

Here's a great test with results that focus on things other than air flow at WOT.


FWIW, all I run now in my vehicles are AC Delco paper filters.
This is why I avoid them, get a performance dry filter if there are any.

Also they are known to just strait let in more contaminants....
