    Looks great and adds a little something extra. Make sure you have a small 3 prong pulley remover to take harmonic balancer off. May have clearance issue on Water Pump Pulley with a stud off the engine block that you will need to either screw in or cut the tip off to the threads.

    Great product looks fantastic in my engine bay. When you go to a parts store to rent the pulley puller, make sure you get the chrysler one with the three prongs, just like the instructions say. My crank pulley was badly rusted so it took about 30 tries to get that thig off, but it was worth it (my mechanical skill is low, so I blame that) I also had a clearance issue with a bolt on the alternator rubbing on the water pump pulley, so I ended up trimming the bolt. Engine revs faster, and I have been getting 30 miles/tank better, which will pay for the part eventually (which is what I told my wife). Great part from AM, I don't buy my parts anywhere else
