Easy Tweaks and a question
I am celebrating the Firs Anniversary purchase of the best car I have ever owned and enjoyed. A 2004 Screaming Yellow Mustang Convertible with 3.9L V6. I was experiencing slight hesitation, changing the air filter to a K&N made a world of difference. It's a difference of night and day and to think If I added cold air induction. as a plus mpg's has also increased. Now it's time to think about moving over to synthetic oil. Any suggestions as to oil and filter?
