NISSAN GENUINE SPARK PLUG 22401-ED815 (4PCS)

Description

Nissan Genuine 22401-ED815 – Authentic Made in Japan Laser Platinum Firing Precision for Smooth Drivability

For Japanese passenger sedan, wagon, and SUV owners who refuse to compromise on engine cold-start responses, absolute fuel atomization boundaries, and long-term emission compliance, the NISSAN GENUINE SPARK PLUG 22401-ED815 (4PCS) provides professional-grade ignition mechanics. Sourced as the exact original equipment (OE) specification code co-developed by NGK as the LZKAR6AP-11 profile matrix, this premium kit features a dual-precious metal structure. It is custom-tailored to handle the consistent combustion cycles and tight packaging spaces of modern naturally aspirated multi-valve powerplants, completely eliminating voltage leakage and rough engine idles across demanding local traffic scenarios.

Key Features of NISSAN GENUINE SPARK PLUG 22401-ED815 (4PCS):

• Genuine Japanese Engineering: Manufactured and calibrated inside premium Japanese facilities to assure precise quality threshold limits, uniform electrode alignment, and complete structural defense against high-voltage stress.
• NGK LZKAR6AP-11 Double Platinum Sizing: Configured with a fine-wire laser-welded Platinum center electrode tip matched against a targeted Platinum inlay pad on the ground interface, drastically slowing down gap widening.
• Optimal Heat Range 6 Insulation: Designed as a stable mid-range thermal conductor to perfectly prevent low-speed carbon fouling during continuous idling, while effectively dissipating heat at higher RPM highway cruising speeds.
• Trivalent Zinc-Nickel Plated Threads: Finished with machine-rolled anti-seize precision threads that firmly lock away moisture, resist thread binding, and guarantee easy extraction blocks during future tune-ups.

Why Choose NISSAN GENUINE SPARK PLUG 22401-ED815 (4PCS)?

The high ambient humidity, intense stop-and-go congestion blocks, and varying fuel composition metrics across Bangladesh put continuous thermal and electrical load on family-driven vehicle lines. In models like the Sylphy G11 or X-Trail T31, non-standard low-grade plugs experience immediate tip degradation, resulting in annoying engine vibration ripples, loss of low-end torque, or high fuel consumption trends. The NISSAN GENUINE SPARK PLUG 22401-ED815 (4PCS) available at Oil House Bangladesh stands as your vehicle’s factory-intended insurance policy, maintaining your powerplant smooth, silent, and flawlessly efficient.

Application Instructions

1. Park the vehicle on level ground, shift into park, shut off the ignition layout completely, and let the engine compartment cool down entirely.
2. Unfasten the decorative plastic engine engine vanity cover line to gain access to the direct coil configuration.
3. Carefully unclip the wiring harness connectors from the individual high-tension ignition coils.
4. Extract the holding bolts using a standard wrench, then gently pull the ignition coils vertically out from the deep plug well tubes.
5. Use compressed air to blow away any hidden dirt, dust, or sand particles from inside the plug tubes before unscrewing the old units.
6. Loosen and extract the spent spark plugs counter-clockwise using a proper magnetic 14mm thin-wall spark plug socket.
7. Hand-thread the new NISSAN GENUINE SPARK PLUG 22401-ED815 (4PCS) clockwise to eliminate cross-threading issues, then torque to exactly 15–20 Nm using a torque wrench.
8. Set the ignition coils back into place, secure the retaining bolts, click on the harness plugs, start the car, and confirm a crisp, solid engine baseline idle.

Note: Fitment depends entirely on your exact engine configuration code and chassis guidelines. This plug is optimized for Nissan’s naturally aspirated HR15DE and MR20DE multi-valve direct coil engines and will not map with newer direct-injected DIG-T turbo variations or e-POWER hybrid generation platforms. Please verify your manual or share your chassis number with us to verify compatibility before ordering.

Maintenance Tip from Oil House Bangladesh:

Nissan’s HR and MR multi-valve engines are highly resilient daily workhorses, but they are particularly sensitive to ignition voltage stability to maintain peak economy. Under the high-temperature stop-and-go city grid traffic, heavy fuel evaporation rates, and unpredictable fuel octane profiles across Bangladesh, spark gaps undergo accelerated micro-erosion stress. To preserve your engine’s velvety-smooth engine idle line, guarantee instant overtaking throttle response, and shield your high-tension ignition coil packs from early thermal insulation degradation, we highly recommend replacing your NISSAN GENUINE SPARK PLUG 22401-ED815 (4PCS) every 50,000 km to 60,000 km in local driving zones. Additionally, always make sure the deep plug cylinder wells are thoroughly dry and free of any leaked engine oil from worn valve cover gaskets during every plug replacement service.
