How do you replace the spark plugs on a 2001 Kia Sephia?
Hi , If you still need to know where your spark plugs are I can tell you. There is a cover between the valve covers on the motor with 6 Phillips head screws. On top of the cover it reads "DOHC 16 Valve " Remove the cover and you will see #1 and #3 cylinder spark plug boots . #2 and #4 have a coil PAC on top of the spark plug boot. remove the 4 bolts ,2 each , and remove the coil pacs to get to the plugs. You will need a socket extension as you will see.
I have a 2001 Kia Sephia and changed my plugs today . Have fun , Bob

TIME?!? You mean, how many miles before you have to replace it? Whatever it says on the box. If you're talking about replacement time, about 5 mins. Contrary to the previous answer, the time required to actually replace all 8 spark plugs on the 4.6 litre engine is 60 minutes. You'll need a univeral for your wrench to get the ones in the back.
