    I recently bought and installed this myself. It's sad that Harley would put a plastic piece of junk on one of their bikes, but, "muh costs," I guess. Anyway, a quick YouTube search produces plenty of good "how to" videos on installing this part. It's well-made, and everything hooks right up with no issue. Anyone with a decent amount of mechanical ability can install this in about 1.5 hours. You might need to clear codes like I did, but my bike runs great now with zero problems. I highly recommend replacing the plastic crap with this piece. read more.

    The seals wore out on the plastic intake manifold so as long as I was doing it upgraded to aluminum. No noticeable change in performance. More piece of mind not being plastic.

    Was extremely easy to bolt up only took couple of hours and I took my time then did auto tune on my pv3 runs excellent. my plastic intake manifold seems to be in perfect condition yet at 20,000 miles. Probably really didn't need to do the upgrade but gave me something to do
