Hello everyone im new to the forum, was browsing around and didn't see any post on increasing MPG via replacement parts. I have a friend who replaced a few parts in is Mazda6 under the hood to gain HP and MPG, via light weight pulleys spacers etc. Is there anything out there like that for a 2002 TL S?

Keeping your car properly maintained. Changing out your spark plugs upon servicing. Regular oil changes. Cleaning your intake filter. Not driving with a heavy foot. Just things I can think of on the top of my head
