NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS)

Description

Step up to elite combustion control with the genuine, high-performance NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS). Designed to meet the stringent technical requirements of next-generation high-compression engines, this Laser Iridium series provides the ultimate defense against extreme cylinder temperatures and pre-ignition risks.

By utilizing a fine-wire Iridium center core paired with a laser-welded platinum chip on the ground electrode, it creates an exceptionally resilient firing gap that completely resists electrical erosion. This advanced dual-precious metal configuration lowers the overall voltage demand on your ignition coils, ensuring quick cold-starts, a completely stable engine idle, and immediate throttle execution.

Key Features of NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS):

• Laser-Welded Dual Precious Metal: Features a continuous-weld Iridium center tip and a platinum ground electrode pad, completely locking the pre-set spark gap against widening under heavy load.
• Standard Heat Range 6 Rating: Engineered with a specialized high-heat dissipation ceramic insulator, making it perfect for maintaining optimal thermal balance across both daily city commuting and highway driving.
• Anti-Seize Trivalent Metal Plating: The shell is treated with an advanced machine-rolled zinc-chromate coating, ensuring superior moisture protection and preventing the threads from seizing inside aluminum cylinder heads.
• Extended Long Reach Profile: Designed with an advanced long-thread architecture to position the spark precisely within modern combustion chamber boundaries for complete flame propagation.

Why Choose NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS)?

Modern passenger vehicles running daily in Bangladesh face intense operating stress due to heavy traffic congestion, high ambient heat, and volatile fuel quality variations. These harsh conditions quickly degrade standard plugs, causing severe carbon fouling, engine misfires, and noticeable power loss under acceleration.

Upgrading to the authentic NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS) from Oil House Bangladesh ensures your engine safely extracts maximum performance from local fuel. It delivers complete fuel atomization, preventing unburnt fuel deposits from contaminating your catalytic converter and maximizing your total mileage.

Application Instructions for NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS):

1. Safely park the vehicle, switch off the ignition, and allow the engine block to cool down completely before beginning installation.
2. Unbolt and carefully pull the individual direct ignition coil packs vertically out of the deep spark plug tubes.
3. Use a compressed air line to blow away any hidden sand, dust, or micro debris around the cylinder entry points.
4. Slowly extract the old spark plugs counter-clockwise using a specialized 14mm Bi-Hex (12-point) spark plug socket tool.
5. Thread the new NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS) units into place by hand clockwise first to eliminate any risk of cross-threading.
6. Use a calibrated torque wrench to final-tighten the plugs to exactly 15–20 Nm to secure a safe mechanical seal against the aluminum head.
7. Reattach the coil packs, fasten the holding bolts, reconnect the harness clips, and start the vehicle to check for a smooth, balanced idle.

Critical Fitment Note: This plug features a specialized M12 thread diameter with an extended 26.5mm reach and requires a 14mm 12-point (Bi-Hex) socket. It will not fit older engine models that use traditional 16mm hex plugs or standard M14 thread dimensions. Please confirm your engine code or consult with our team before purchasing to guarantee absolute fitment.

Maintenance Tip from Oil House Bangladesh:

Modern naturally aspirated platforms operating within the heavy stop-and-go traffic conditions of Bangladesh can accelerate carbon accumulation along the plug’s ceramic insulator due to frequent engine idling.

To maintain peak fuel responsiveness, prevent high-RPM ignition blow-out, and safeguard your ignition coils from premature failure, we highly recommend replacing your NGK LASER IRIDIUM DILKAR6A-11 SPARK PLUGS (4PCS) set every 60,000 km to 70,000 km. Always verify during installation that your spark plug tube walls are completely bone-dry and free from any engine oil weeping down from the upper valve cover packings.
