    I was able to replace this in 15 minutes on my 4.0 Grand Cherokee. I did notice an increase in performance. I would have to measure fuel saving during this first week of install but it would be logical to think there is gas saving when you get to burn fuel more efficiently.

          product is easy to install mounts to original bracket with 2 screws, your going to need a impact driver to loosen the screws though.

              I bought this coil for a project truck. Upon trying to install it I realized that even though it says exact fit, it's not. so then it was either buy a new harness or the junk coil. BWD it is.

                              The car accelerates better, did not notice fuel efficiency nor an increase in power. I did a complete tuneup including oxygen sensors. It will be hard to attribute any gains on just one thing. But over all the engine feels more responsive. 97 TJ 4.0
