Here's the follow up video on the BMC filter.

I don't think the BMC or K&N type filters are bad in any way. In fact, I ran them on my 355 and 360 without any issues whatsoever. And as this video shows, I think any fears of the BMC filter melting under normal operating conditions are largely unfounded. I was actually very impressed with how well it withstood direct heat.

I also think it confirms that the BMC filter tends to flow better.

I will say this:

In hindsight, if I was planning to install an aftermarket exhaust (which myself, I probably don't think I'm going to do), then I think I would probably make the slightly larger upfront initial investment and go for the full air box from BMC - the one that has the twin cone filters inside. It's more pricey than just a filter change, but I think the full CF airbox design might help mitigate heat a bit more (as compared to the metal factory airbox) and also help improve airflow over the stock setup.

Anyway, I put the video up for anyone that might be interested in seeing it what I went through as far as checking to see how well the rubber withstands direct heat. Yes, I ended up putting the factory air filter back in for now, but a big part of that was because I'm probably going to stick with the factory exhaust for now also.

Thanks for the writeup Ray!

It's actually good to see that both filters hold up to the heat really well;
the smoke coming off the BMC unit is probably just the oil evaporating, even more so because the filter
is new and it comes pre-oiled at the factory. Like I said I have mine cleaned and re-oiled every year.

Yes, I think so as well. I re-oil my K&N filters every couple of years myself over here. I agree it's just oil vapor due to the extreme temperature of the heat gun.
