[V8] cheaper air filter

I think it works the other way Ed. More pleats means more surface area means 
better air flow, and a longer lasting filter. The fact that the BMW app is a 
bit taller may equal things out though.

Because those filters are so much cheaper it may well be worth it to use them 
and replace more often.
