Review part 77-2585KS
Had a mechanic friend put this in for me on my 2013 F-150. It took him just over an hour. Instantly saw better gas mileage. Went from averaging 15mpg to 18mpg which is the main reason I got it! Sounds good when you rev it too. Hard to gauge the horsepower increase but I'm sure it's there.
Love this product.
Except for a shipping problem,left out attaching parts,I would recommend this product to anyone looking for better engine performance.
I picked up 2 MPG right off the bat.
Love the more muscular sound of the engine.
