Night and day difference

The sensor is kind of a pita to install on the lower charge pipe, but other than that, it's simple and straightforward, and the pigtails make it all the more easier to install!

Easy install, preventative maintenance item, AWESOME harnesses!

Easy install and preventative maintenance item if you ask me, the stock sensors failed twice in the short time I have had the car (No tune/ stock until now). The only thing I had an issue with was finding the correct O-ring for these to fit into the stock locations. The provided "Green" Bosch O-rings were too small and created a nasty charge air leak. Ordered some #202 Viton o-rings which corrected the issue. Would be good to include a basic set of instructions so new or budding mechanics could do it themselves and possibly supply the correct o-rings as well. The harness is a life saver for a DIY garage mechanic makes things easy and whether tight which is essential if you live any where near salted roads.
