You can but not necessary unless you experience hesitations (misfires) after you do. You'll know right away and usually it's just one of the coils.
Thank you for your reply. Hopefully I wont need to and I can save $$$
I bought a couple lifetime replacement coils from Autozone and so far so good. They also look better built than the Bosch coils but who really knows?
How many miles you have now?
Nope. Unless there's a fault they're good.
Injectors same.
Intake valves, not so much! If you're near 60k mi since last blast, time t'do it again....
