I've been experiencing some hesitation and missing on acceleration for a

it is to change them in the Elantra I picked up a set of NGK copper. I
pulled the old plugs and discovered they had burned to the extent that the
gap was at least 2X the spec. That pretty much explained the problem.
Since putting in the new plugs it feels like the car has come out of
Regarding the fuel filter, I know it's inside the gas tank and I'm reluctant
to take it on. Would there be any obvious issues if the filter was needing

As for the fuel filter, it is essentially non-serviceable. I wouldn't worry
about it. But DO worry about the timing belt.
Oh, and if you only put copper plugs in your car, don't go more than 30,000
until your next change. And when you do change them out again, use some
kind of platinum (or irridium) plug.
