After fitting it in outside of the store....
I noticed on the very 1st start up an improvement in tone, a very pleasing rubble.
On driving the rubble is certainly there under any kind of throttle use, no matter how slight - which gives 5.0 the sound that I think it should have.
It also gives a smoothness that is very apparent even after a short journey.
I have also noticed an improvement of 0.5mpg on the average mpg on the trip computer without resetting it at all - which is a pleasant surprise.
If this continues in the future months and years the filter should certainly prove it’s worth in many ways.
What kind of vehicle do you drive? 2017 Ford F-150 xlt 5.0 2wd
