How to improve MPG on a 99 Toyota SR5 Prerunner 2.7 eng w/ auto?
Stock sized tires,Bosch 2 point plugs, new spark plug leads ( top shelf not cheap ones), Ams oil in engine,clean stock air filter and intake. 140,000 miles. Currently 22 / 18 MPG.
Is there anyone out there with the same truck who has truely gotten better MPG with a cold air intake and a cat back over sized exhust? Thinking of doing that and maybe change out the twin coils.
I don't need any remarks from 2 pointers. Thank you! Just those who have really done it and can offer up some real information please.
Thank you for the time and effort.
Alinement, tire pressure, fuel filter are fine.
Again those of you with to much time and want to sling some B.S. STAY AWAY>

On my '99 Tacoma, I had the suspension checked along with a full alignment. Make sure no tires are wearing wrong and keep your air checked in your tires. I dont know what tires you have but they can make a big difference. I got about 40 more miles a tank.

Try some nitrogen in your tires. Some say they get a few extra miles per gal.
