I personally wouldn't use the K&N. I did for years but after what I saw in my oil studies and the couple of failed MAFS I've had (different vehicles), that's just my personal choice.
There's tons of arguements FOR and AGAINEST K&N filters. If K&N filters are as bad as a lot of folks think they are - the company wouldn't be in business. But obviously, they continue to make them and sell them.
I highly doubt a Toyota Technician is an expert on K&N filters. Anyone can perform studies and anyone can read about studies performed about them - that doesn't make you an expert. The only people qualified to be experts about them - are the engineers who've designed them and tested them (and continue to test them). *On a side note - some Toyota Techs can't even do their own job let alone be an expert at anything*
In this situation - The Toyota Tech is being lazy. Immediately blaming the problem on the K&N and rendering his job *done* without checking into other things. Not to mention - in the process, pissing off the customer (JDB).
Like everything else in the world - (as you mentioned above), it's a personal choice. I've had K&N for years on various vehicles and I've never had any problems or complaints about them. I'd buy them again. So who's right?
Nobody is right or wrong. It's personal preference.
