OEM-Replacement Spark Plug Wire Set Built for 1979-1983 Nissan 200SX Reliability
The NGK 8115 is a factory-spec spark plug wire set engineered specifically for the 1979-1983 Nissan 200SX. Designed to restore ignition performance and eliminate misfires caused by cracked, carbon-tracked, or high-resistance factory wiring, NGK 8115 delivers accurate spark timing from distributor to plug with minimal energy loss. Each wire is cut and terminated to factory length for a no-trim installation.
Key Features
- Vehicle-specific design for 1979-1983 Nissan 200SX, direct OEM replacement
- Spiral-wound suppression core reduces RFI interference with modern electronics
- Silicone insulation withstands underhood heat, oil, and chemical exposure
- Factory-length pre-terminated wires install without cutting or re-terminating
- Boots seal tightly to plugs and distributor cap to prevent moisture intrusion
- Low-resistance core maintains consistent spark energy under all RPM ranges
- Complete set covers all cylinders for a full ignition tune-up

Frequently Asked Questions
Does the NGK 8115 fit all trim levels of the 1979-1983 Nissan 200SX?The NGK 8115 wire set is designed for the 1979-1983 Nissan 200SX. Confirm your specific engine displacement before ordering, as different engine variants may have different plug wire routing and connector styles.
How do I know if my spark plug wires need replacing on my 200SX?Common symptoms of failing ignition wires include rough idle, misfires under acceleration, poor fuel economy, a visible crack or carbon tracking on the wire insulation, or a resistance reading above 10,000 ohms per foot with a multimeter.
Can I replace spark plug wires one at a time on my Nissan 200SX?It is best practice to replace all wires at the same time using the NGK 8115 complete set. Mixing old and new wires can produce uneven resistance across cylinders and complicate misfire diagnosis.
What is the resistance specification for NGK 8115 spark plug wires?NGK designs their suppression-core wires to maintain low and consistent resistance per foot. Exact values are available in the NGK technical data sheet. As a general rule, any wire reading above 10,000 ohms per foot should be replaced.
Will the NGK 8115 reduce radio frequency interference in my 200SX?Yes. The spiral-wound suppression core in the NGK 8115 is designed to suppress electromagnetic interference that can disrupt radio reception and modern vehicle electronics without sacrificing ignition voltage.
How long do spark plug wires typically last on a classic Nissan 200SX?Under normal conditions, quality suppression-core wires can last 30,000 to 60,000 miles. On a classic vehicle, age and heat cycling of the insulation are often the primary failure modes regardless of mileage.
Are the boots on the NGK 8115 compatible with stock distributor cap terminals?Yes. The NGK 8115 is engineered as a direct replacement for the 1979-1983 Nissan 200SX and terminates to match the OEM distributor cap and plug connector styles.
Should I replace spark plugs at the same time as the wires?It is strongly recommended to replace plugs and wires together for the most complete ignition tune-up. Worn plugs with high firing voltage requirements can accelerate degradation of new wires.
Installation Instructions
- Park the vehicle on a level surface, turn off the engine, and allow it to cool completely.
- Label each original wire or photograph the routing before removal to ensure correct reinstallation order.
- Remove one wire at a time by pulling firmly on the boot, not the wire itself, to avoid damaging the terminal.
- Install each NGK 8115 wire by routing it identically to the original, pressing each boot firmly onto the spark plug until it clicks or seats fully.
- Connect the distributor end of each wire to the matching cap tower.
- Start the engine and verify smooth idle with no misfire.
