    I am seeing some scuttlebut regarding a secondary air pump and it having a filter etc. I did some searching and not sure of some things. Mine is a 14 4.0L. Is there a filter I should be cleaning? I hear of a mod. What does this do? Do I need to be concerned with failure of it? I'm right at 80k miles. Thank you in advance for info...

    Yes your '14 has the secondary air injection, it's the the right of the motor (left side as you look into the engine bay from the front) behind the air intake hose going into the fender.

    It has a foam filter that breaks down and gets sucked into the pump, not a cleaning issue but an integrity issue.

    The pump is part of the '11+ emissions system.

    The mod is to remove the factory filter and fit a "K&N" style mini cone filter.

    The failure can cause a check engine light due to faulty emissions secondary injection pump failure.

    80k/8 years is about the time the oem ones fail as far as I know.

    The 05-10 does not have the secondary injection system.

    The secondary air injection system does nothing more than intake atmospheric air and inject it into the exhaust to cool the exhaust and dilute the exhaust particle concentration in order to pass emissions laws of that year and beyond, It's effectively a loophole and realistically does nothing to reduce emissions overall.

    Interesting... Is the filter mod a pretty simple one to do?

    Plenty of threads on here about it, it takes 5 minutes To change out once you take the cover off pull out the old brittle foam that’s what breaks off and damages the fan component.
