i had a same 'feel' as smgco : the hesitation when applying throttle from standstill in normal drive-mode is almost totally gone. No other.

 

I have used both K&N and Airaid filters on my 2013 GT500 and 2015 GT350 with no oil/MAF issues. I have nearly 2K on my new BMC filters and there is no indication of any oil in the air stream or on the interior of the filter box. Really happy with them and I never have to buy new ones.
