I was trying to solve a fuel cut off issue I was having on my Miata 93 when making a sharp left turn at Thomson Speedway on Turn 5. Not only did this fuel filter solve that problem, it also completely eliminated the hesitation I had between shifts. Upshifts, downshifts and even reversing are much smoother with the new filter and my car has only done 40,000 miles. I changed the spark plugs, wires and even the clutch hydraulics and this filter finally did the trick for a healthy ride. Automobile. I highly recommend it to any Miata owner.
