Review on ECOGARD XF65627 Premium Fuel Filter for Jeep Grand Cherokee 4.0L/4.7L 2002-2004 by Eric Longoria

Great product at a great price. My car's RPM was slightly lower than it should have been. Changed throttle position sensor, air flow sensor and intake manifold pressure sensor. It improved only slightly, but still wasn't up to the right revs. So I changed the fuel filter and my problem was solved. All even though I didn't have an engine code that required a change. I did a little research and found that this fuel filter has a built in fuel pressure regulator. And that seems to have been part of the problem. I also cut open the old filter and found that the filter element was partially clogged and discolored. Thank you for selling such a great product. :)
