SMALLER AIR FILTER??
went to dealer for my 40k mile service. They recommended changing my air filters. The cabin one was fine but the engine filter is SIGNIFICANTLY smaller like half the size! from 17801-0P051 DENSO to YYZ1 DENSO. Maybe it doesn't matter or MAYBE Toyota is using smaller filter to cause more issues it just makes sense to me that it would be the same thickness....why would they do this? Why not provide reasoning? Does it really not matter?
