I’ve had a lot of issues with K&N filters on a number of tuner cars over about 15 years till I stopped using them. The oiled filters seem to always kill the MAF. I have had as many as 4 MAF replacements until I caught on.
a high flow dry filter is my preference now, if not using OEM.
They claim “Gains of Up to 5 WHP and 13 WTQ”, and “Lowered Intake Air Temperatures by an Average of 18 Fahrenheit and Over 22 Throughout the Powerband”.
I found the rattle was the way the connector to the window/lock buttons is loose. I applied electrical tape to the connector and switch and rattle went away.
Things I would like to see:
Convertible rear windows that always close the gap.
360 Copilot standard. (Such a great safety feature)
The Ford Factory EB Performance Tune Option
Revised phone charge pad that had a camera cutout for better flat contact.
Driver accessible gun safe for full sized...
