The IPR TMIC is a pretty beefy unit and feels very solid. The all-metal construction looks like it will hold up much better than the stock TMIC. It was a very tight fit, but once I got it in there weren't any clearance issues. Took quiet a bit longer to wrestle it into place than the stock TMIC, but it does fit and all the bolts line up. Just don't tighten any of them fully until you have them all started. I like the look of the black TMIC in the engine bay
Stock TMIC vs. IPR TMIC
The IPR TMIC only has a slightly larger footprint than the stock TMIC, but it is much thicker.
