FYI, if you have the MMD hood struts be prepared to remove the passenger side strut and the bracket that's attached to the fender. The plastic piece covering the filter wont clear the bracket.
Turns a five minute job into a 10-15 minute job.
I have the MMD struts and just removed the two screws on the cover and was able to flex it past the MMD struts. Just took some elbow grease....
