I know it always comes down to this for you and Toyota/Denso/Honda filters, but somebody really needs to show whether that makes any difference. I've run them on my Toyotas and Honda (since day one on the Toyotas) and I'm still motoring along OK. I cannot bring myself to be concerned about their efficiency. For me, the idea that the the two car makers with the most reliable reputation would purposely sell an OEM-branded product that was detrimental to their brand is just something I am not capable of doing.
I mean it makes for a good long argument thread on BITOG and a lot of nice "I'm better than you" statistics and charts, but after that does it matter at all? I think not.
I simply chose to use filters that are higher in efficiency ... my choice. Doesn't mean I want everyone else to do the same. Obviously, people can use what makes them happy for whatever reason. I'm just pointing out a fact that they are not as efficient as other filters on the market. If that doesn't matter to someone, then great ... if it does matter to someone, then great. It's info people can use to make a decision.
