Oops! That works for most but not this one! Sorry. In an earlier post on 99
Spotage plugs someone offered to post on tech details for removing air
plenum chamber and getting at the plugs which are underneath. Check it out
and chase them up. Need more sleep ... Cheers

you need a special plug socket also, it's about 8" long. if you try to use
a standard socket and extension, you run the risk of loosing the socket
down the hole the plugs are in.
A bitch to get out again. JC Whitney sells one for abouy $7.00. Snap-on
has a better one with a latch on top that grabs the plug, and only
releases it when you are safely out. but you can only get them from
Snap-on if you ask your mechanic to get it for you, as they don't sell to
civilians,
only mechanics. The whitney on just has a rubber "o" ring that grips the
plug.
Oh yes one other thing. I have been told to never use platium plugs in a
Kia. the faster firing capability plays havoc with the computer.
