Hyundai Elantra Spark Plug Torque Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Spark plug torque | 14.7–24.5 N·m | 10.8–18.1 lb-ft |
| Ignition coil torque | 9.8–11.8 N·m | 7.2–8.7 lb-ft |
| Electrode gap | 1.0–1.1 mm | 0.0394–0.0433 in |
| Listed plug types | SILZKR6B11 / RER8WMPB4 | Verify current catalog supersession |
The factory table identifies SILZKR6B11 and RER8WMPB4 plug types for the covered application. Keep contaminants out of the wells, hand-start plugs in a cool head and do not convert the published range into a universal Hyundai value.
Torque range, gap and coil fastener are separate values
Hyundai publishes 14.7–24.5 N·m for the plug and 9.8–11.8 N·m for the ignition-coil fastener. Confusing the two can leave a plug loose or damage the small coil bolt. Set the torque wrench from the correct row.
The same inspection procedure lists a 1.0–1.1-mm electrode gap. The specification image identifies SILZKR6B11 and RER8WMPB4, but a current parts catalog should confirm any supersession before purchase.
A clean installation protects the aluminum head
Work cold, disconnect coils by their locks rather than pulling wires and remove debris before the plugs come out. The service procedure warns against letting contaminants enter through the plug holes.
Thread replacements fully by hand, then apply the published clean-thread range. Seat coils squarely so their sealing caps meet the cover, tighten their separate fasteners and reconnect every lock. A fresh misfire after service often traces to seating or connection, not the plug gap.
