Nissan Genuine 22401-ED71B – Authentic Made in Japan Long-Reach Iridium Spark Protection for Advanced Powertrains
For Japanese passenger sedan, crossover, and premium family SUV owners who refuse to compromise on structural engine health, instant throttle transitions, and consistent fuel tracking parameters, the NISSAN GENUINE SPARK PLUG 22401-ED71B (4PCS) provides professional-grade ignition mechanics. Sourced directly as the exact original equipment (OE) benchmark specification co-developed under the FXE20HE11 dual precious metal standard, this premium kit features an extended deep-reach design. It is custom-tailored to handle the dense thermal loads and localized high cylinder pressures of Nissan’s eco-efficient and flagship utility blocks, completely eliminating high-voltage ignition spark blowout across demanding urban tracks.
Key Features of NISSAN GENUINE SPARK PLUG 22401-ED71B (4PCS):
- Genuine Japanese Manufacturing: Precision crafted and laboratory tested in Japan to guarantee peak material durability, flawless core alignment, and absolute resistance against micro-cracking under intense stress.
- Dual-Precious Metal Construction Matrix: Features a highly focused fine-wire Iridium center core integrated with a robust Platinum mass earth ground pad interface, locking away early gap erosion anomalies down to the millimeter.
- Extended 28.5mm Deep-Reach Core: Engineered as a dedicated deep-chamber layout to optimize flame front positioning inside modern high-efficiency combustion boundaries, maximizing complete fuel burn profiles.
- Trivalent Metal Anti-Seize Thread Plating: Coated with a protective outer shell plating barrier that blocks cylinder head moisture rust, prevents thread binding, and ensures seamless extraction cycles during service periods.
Why Choose NISSAN GENUINE SPARK PLUG 22401-ED71B (4PCS)? The dense traffic gridlocks, high ambient humidity, and fuel composition variances found within Bangladesh throw massive thermal strain at modern direct-injected and high-capacity passenger blocks. In systems running specialized HR, MR, or QR architectures—including the common X-Trail T32 2.5L configuration—generic short-reach or wrong heat range specifications cause fast carbon fouling, leading to annoying engine vibration ripples, sluggish throttle transitions, or bad fuel tracking metrics. The NISSAN GENUINE SPARK PLUG 22401-ED71B (4PCS) available at Oil House Bangladesh delivers an authentic, rock-solid shield for your engine, keeping your performance curve seamless, ultra-quiet, and fully responsive.

Application Instructions
- Park the vehicle on level ground, apply the parking brake, turn off the motor completely, and allow the engine bay to cool down entirely.
- Unclip the decorative plastic vanity cover assembly line to clear the pathways to the direct coil layout packs.
- Carefully unfasten the locking electrical harness clips from the individual ignition coil connectors.
- Extract the holding bolts using a proper wrench, then gently pull the individual ignition coils vertically out of the plug wells.
- Use compressed air to blow out any loose sand, dust, or moisture remnants inside the plug tubes before removing the older units.
- Loosen and extract the worn spark plugs counter-clockwise using a proper magnetic 14mm thin-wall spark plug socket.
- Hand-thread the new NISSAN GENUINE SPARK PLUG 22401-ED71B (4PCS) clockwise to eliminate cross-threading issues, then torque to exactly 15–20 Nm (do not over-tighten).
- Reinstall the ignition coils, secure the mounting bolts, reconnect the harness clips, start the vehicle, and confirm a crisp, solid engine baseline idle line.

Note: Fitment depends entirely on your exact engine configuration code and deep cylinder head clearances. This plug is strictly optimized for modern Nissan long-reach multi-valve platforms featuring specialized 28.5mm thread depths—specifically tracking with the Non-Hybrid 2.5L platforms in the T32 sequence—and will not map with short-reach 26.5mm engine paths. Please check your user manual or share your chassis number with us to confirm fitment before placing an order.
Maintenance Tip from Oil House Bangladesh:
Advanced deep-chamber systems and high-capacity architectures like Nissan’s QR25DE configurations inside the X-Trail T32 run notably higher internal combustion flame fronts, accelerated electrical spark resistance, and specific thermal pressures. Given the demanding stop-and-go road blocks and uncalibrated fuel moisture traits across Bangladesh, maintaining optimal dual-precious metal gap clearances is vital to prevent tracking misfires and rough cold-start hesitations. To keep your engine’s power tracking lines perfectly flat, secure maximum fuel thrift, and save your primary high-tension ignition coil packs from early stress breakdowns, we highly recommend replacing your NISSAN GENUINE SPARK PLUG 22401-ED71B (4PCS) between 50,000 km to 60,000 km in local driving zones. Always check that the internal spark plug tube wells are completely dry and free from any valve cover motor oil wet spots during your regular vehicle maintenance routines.
