road trip question
so i love driving my focus as most of us on here do. i take some road trips to upstate new york to visit my girlfriends family, and once a year we take a drive up to canada. i have had my fswerks header sitting in a box waiting for the weather to get a little nicer to install it. as i was driving home from work this morning i was wondering about the header and road trips. will having the header installed and driving for say 8 hours in a day at 70+ mph hurt my car?
