2000 Sonata 4 Cyl Plug replacement help
 

First time owner. Any suggestions on 4 cyl spark plug replacement?
Tips, correct plug type, etc. I assume they are located under the top engine cover? Is this a hemi? I see its a DOHC. Thanks for any suggestions. (scan code read "misfire", I'll start with plugs and work up the the more expensive stuff! :cool: ) Thanks

Visit the Autozone site, or go to the local Walmart for plug numbers. I buy cheap Autolite platinum from Walmart myself.

Hyundai recomended plugs are NGK PGR5C-11 plug or the Champion RN10PYP4
Both are double platinum plugs and are rated for 100K. Champion is usually less expensive but as good as NGK. If you plan to use an other plug be sure it's in the same temperature range and double platinum for durability.

Your misfire error may also be related to bad wires or ignition coil.
