So, I did a tune up today. Changed the Cap, Rotor and plugs. Cap and Rotor looked pretty good (DUI performance) with 2.5 seasons of use. Plugs looked a little worn, they were the AC Rapid Fire #1's. I think this was the 4th season, seeing that you can run them in a car for 100k I ran them a little longer than normal. I went back to the NGK BR6FS, for the cost difference I can change them every year. I am going out on Sat and let you guys know if I get the speed back.
