Well, I installed the MS filter. While it wasn't as easy as advertised, I'm glad IND included the bigger adapter at no extra charge. Thank you IND!
I went out for a spirited run afterwards. While I can't feel any noticeable change in sound or power, I feel good knowing that the engine can breathe a little better. The OEM filter was filthy after 12000 miles. I'm glad I took the plunge. It was a relatively cheap 'mod'(if i can call it that).
I'll keep the AA air filter in mind for the next one. After all, I'm an equal opportunity consumer.
