Changed plugs and a few other things today. What a difference!

Ordered the valve things from pelican parts came in one day, I must be close, super easy to change however I would not be in such a rush to blow 50 bucks my old ones looked like new... But they could tear at any moment I guess I have 80k miles and I would vote it's a 100k item or so

They needed to be changed...they had a lot of buildup on them. it would have run poorly IMO (drop in fuel mileage, rough idle, vibration, etc) if i let them stay there until 100k.
Somehow the car was still getting 25 MPG average, more on long trips with the original plugs. With the new plugs, it definitely feels like its picked up some power. Fuel mileage will have to wait...this tank does look like it could be best anyway, my foot has been a little heavy
Bottom line: Well worth the 45$ and the hour to put them in. I used Bosch IR Fusion Platinum plugs. OEM's were NGK.
