  1. 2.7 Ecoboost F150
    I have had my 70k mile 2018 2.7 Lariat for only less than a month, and the other day on my day off I decided to change the spark plugs because I wasn't quite getting the MPG I thought I should be getting and I had tried everything else so I figured I should go ahead and change the factory ones...

    Whats up guys. Back in the day I did all my work on my Mustang GT. That was 10 years ago. Now I mostly make sure my kid doesn't eat stink bugs off the floor. Two quick questions: 1) What are good spark plugs for the eco? I use(d) NGK on my Mustang that worked great. Is there a NGK...

    The answer? New plugs and a catch can! I recently picked up a 2016 F150 2.7L 4x4 with 82k highway miles. When I had my '13 FX2, I added a catch can and swapped plugs when I bought it. It really helped, so I figured the same for this 2.7L engine. I got the JLT catch can for $140 and new plugs for...
