K&N Dropin = bad MAF

I think this case was just a fluke - but the MAF sensnor is too costly to take a chance
IMPORTANT - the K & N drop in has proven very reliable and this is a very rare occurence
This is not meant to be K&N bashing, I think they make a good product in general

Do not use this filter IMO. See the dynoflash thread for more info if you want.

The Toyota people once told me that TRD likes to "over oil" their filters from the factory so they don't dry out sitting on the shelf. I am assuming this would apply to K&N also. So therefore, you can play it safe by cleaning and re-oiling the filter yourself if you want. That should fix the problem, unless you over oil it yourself.
