Denso Spark Plug Wire Set - B-Series & D-Series
Spark plug wires carry the spark from your distributor to the plugs, and on a 20-to-30-year-old Honda, the originals are usually cracked, hardened, and leaking voltage, which shows up as a misfire, rough running, and a car that won't rev cleanly. These are OEM-quality Denso wire sets, cut to exact length with proper end caps, for the B-series and D-series engines. Three versions cover different engines, so match yours before ordering.
Match Your Engine — Three Versions
The most important thing on this page, because the wire set has to match your specific engine.
| Part Number | Fits |
|---|---|
| DEN-671-4176 | D15 (88-95 Civic/CRX), B17A1, B18C1 GS-R |
| DEN-671-4179 | B16A3, B18C5 Type R |
| DEN-671-4186 | B18/B20 non-VTEC |
Go by your engine code, since these differ by the distributor and wire routing of each engine. If you're not certain which engine you have, confirm it before ordering rather than guessing, the wrong set won't route or seat correctly.
Why Old Wires Cause Problems
Worth understanding, because failing wires are a common and often misdiagnosed issue on these cars.
A spark plug wire has to carry tens of thousands of volts from the distributor to the plug without leaking any along the way. The insulation degrades over decades of heat cycling, and once it cracks or breaks down, voltage escapes to ground instead of reaching the plug. That cylinder misfires, especially under load or in damp weather, which is exactly when you'll notice it.
People chase these misfires everywhere, plugs, coil, fuel, when tired wires are a frequent culprit. On an engine this age with the original wires, fresh ones are cheap insurance and often the fix for a running problem you've been hunting.
Cut To Length With Proper End Caps
What makes these a clean install rather than a fight.
Each wire is pre-cut to the exact length for its position, so you're not trimming universal wire or fighting excess length, they route the way the factory wires did. The OE-style end caps click securely into place, and Denso's connection process is built to prevent the cable and boot separating when you pull a wire off, which is a common frustration with cheap wires where the boot stays on the plug and the wire comes off in your hand.
Denso's First Time Fit standard means these match the factory wires in form, fit, and color, so it's a straight, correct replacement with no adapting.
OEM-Quality, Not A Cheap Set
Wires are a part where quality genuinely matters.
These meet or exceed OE and Denso standards, which means proper resistance, proper insulation, and durable construction. A cheap wire set can have inconsistent resistance or thin insulation that breaks down again quickly, putting you right back where you started. Denso is an OE-quality supplier, so these deliver consistent ignition and last rather than being a repeat job.
