Query: Better Power & MPG !

I own a 93 Toyota p/u with the 22re motor with 195K on the clock. Had a engine light on and code was "21" oxy sensor so replaced it was easy to do 10 minute job leads are a little longer then the stock one just used a strap to keep it from hitting the hot exhaust. Runs smoother better power and better mpg that's a win in my book !
