Nah you're right. Because more expensive OEM high pressure fuel pumps, injectors, water pumps, coolant lines, charge pipes, etc. are much higher quality and never fail. Right?
"On a stock engine this is suicide." .... 
Please stop drinking the dealership kool-aid. Aloop lot of the companies that make aftermarket components are also OEM suppliers. It's ridiculous to think that a filter from a reputable company will blow your engine. The fact that you still think it lets larger debris through, much less debris large enough to damage your engine, shows how little you know. Meanwhile the factory engine configuration is shoveling oil vapor into the intake tract to be burned off. But it's just another part of the expensive OEM design, so it must be fine. |
These 1950's tech air filters could let dirt in which scored the cylinder walls OR it could simply be an improperly seated filter.
Dealers want to get paid for warranty work so they don't have an incentive to deny work.
Also, they could be under the microscope for performing questionable warranty repairs.
