I got an oil change today and the guy told me that I needed to get a new fuel filter and I was like "Sweet, opportunity to upgrade" so I go get my 96 300ZX Purolator fuel filter from Pep Boys, swap it in, and instantly feel a difference especially in the lower rpm's in 1st and 2nd gears.
Pretty sure that the fuel filter made the difference, not sure if it was because my old one was bad and I just put a new one on or because it was the "super upgrade" that I did but it did make a difference. Placebo maybe, but I like to think it was the 300ZX that made the difference.
