I have one on my 96 and I had one on my Hot Rod 99 but it restricted fuel flow way to much. In 135,000 (on my 96) miles I have not had any trouble with my TPS and I do change my filter every 10,000 miles. I HATED the stock filter location, at 6'3" and 290 lbs it was not easy to change. If the Primeloc was not on my 96 I probably would drag out filter chages as long as I could.
