Try sending a Private Message to Charles R. Hill, he is a forum vendor and might have ignition coils at a great price.

As for installation instructions, it's pretty straight forward.
Pop the hood, remove the engine cover.
See where the spark plug wires are? Well, the little black pieces they connect to are the ignition coils.

when you receive your new coils (4), simply replace them one at a time. They are universal so any coil can go in any spot.
You'll need a ratchet, extension, and I think it might be a 10mm socket. (could be wrong on the socket size)
-Loosen the spark plug wire
- use ratchet to loosen bolt
- remove coil
- insert new coil.

Do this one at a time so you don't plug the spark plug wire into the wrong coil.

Thank you all your help.

Do I need to take out air filter or something? If so, how can I take it out?
And I would like to change spark plugs but don't really know where to get'em either.
Can you guys help me out on that?

hey mlee:
You might need to take off the rubber accordian piece on your intake. It should have some clamps on it that you can loosen with a screwdriver or it might be an allen key. It might make it easier to get to the coils.

As for the spark plugs. Check with some of our vendors to see if they have any in stock. Do not use any other type of plug, the OEM ones are the ideal solution for your car.

Also, there is a Do It Yourself subforum that has a thread dedicated to replacing the spark plugs. Take a look there or use the search button towards the top right to locate the thread.

be careful pulling the hose fittings loose from the rubber intake accordian, they get brittle with time and can break

smear a light coating of grease on the fitting end before re-installing them into the rubber accordian, they will then slide out/in much easier in the future

For that price it would be each.
