Changing Spark plug wires

^This.

If you don't find any problems, stick them back in, unless this is solely preventive maintenance.

I just did a Mitsuchrysler with the wrapover manifold. I didn't even bother checking them. When you have to do THAT much to get at plug wires, just change them.

I'd save my money until I could afford the plugs and the wires. Reason being on some cars the wires become welded to plug and you have to split the boot to get them off. Ask me how I know. Case in point 00 Century original wires, 80K miles. I had to split 5 of 6 boots to remove the wires. All the plugs on the side of the engine facing the firewall were impossible to remove any other way.

How old , how many miles? Yrs ago, I bought an old Willys for a toy. Soon after, we had twins. The Jeep got hard to start when there was condensation on the wires. I bought a tube of silicone boot grease and worked it into the wires. It worked. Unless the car is running poorly, why change anything.? These days spark plugs last longer than in days of yore.

PS Original plug wires are usually better than after mkt. Start saving for parts. How are the filters and belts?

What does Hyundai recommend and what are the OEM plugs?
If they're double plats, and they probably are, they'll be fine until you're a little more flush.
This car is apparently only driven 11K each year, and another 11K won't cause any problems, so you probably have an entire year to get to a financial state where the need to replace the wires won't hurt, should that need arise.
It may, as many others have noted.
After six years and 89K of heat cycling, the boots may not come off of the plugs cleanly and you may end up having to buy new wires.
As long as there are no problems in starting the car on damp mornings, I'd leave well enough alone until you can more easily afford the whole enchilada.
