HONDA OEM SPARK PLUG 12290-6A0-A01 (4PCS)

Description

HONDA OEM 12290-6A0-A01 – Elite Ignition System for New-Generation VTEC Turbo Engines

For next-generation Japanese sedan and premium crossover SUV owners who demand flawless combustion under extreme compression thresholds, the HONDA OEM SPARK PLUG 12290-6A0-A01 (4PCS) delivers top-tier performance engineering. Originally manufactured by NGK as the definitive factory benchmark for Honda’s direct-injected forced induction powerplants, this Laser Iridium series features a cold Heat Range 8 layout. It is custom-tailored to combat the aggressive internal temperatures of newer generation high-output turbo profiles, eliminating voltage leak paths and stabilizing high-rpm throttle responses flawlessly.

Key Features of HONDA OEM SPARK PLUG 12290-6A0-A01 (4PCS):

• NGK DILKAR8P8SY Production Specification: Built with a specialized dual-precious metal matrix featuring a fine-wire Laser Iridium center tip and a platinum-anchored square ground structure for ultra-crisp flame kernels.
• Cold Heat Range 8 Architecture: Configured as an elite cold-type spark core to quickly move excess thermal energy away from the combustion chamber dome, actively preventing unsafe pre-ignition anomalies.
• High-Ignitability Square Ground Design: The advanced earthed electrode profile reduces voltage demand from the ignition system, maintaining constant power consistency even during intense boost sweeps.
• Trivalent Metal Exterior Plating: Finished with machine-rolled precision threads and anti-seize plating that isolates moisture, blocks head-seizure, and guarantees safe extraction steps.

Why Choose HONDA OEM SPARK PLUG 12290-6A0-A01 (4PCS)?

The high ambient humidity, continuous traffic crawl zones, and variable fuel composition found in Bangladesh subject direct-injected turbo platforms to severe pre-ignition stresses. Standard basic plugs cannot handle the high-load tuning profiles of newer 1.5T or 2.0T engines, leading to engine knock code errors or drop-offs in performance. The HONDA OEM SPARK PLUG 12290-6A0-A01 (4PCS) sourced directly from Oil House Bangladesh keeps your modern Earth Dreams vehicle operating with continuous performance, maximum economy, and factory smoothness.

Application Instructions

1. Shut off the vehicle engine on level ground and let it cool down entirely.
2. Carefully detach the engine plastic top cover and disconnect the ignition coil wiring harness clips.
3. Extract the holding bolt and pull the individual ignition coils straight out from the spark plug tubes.
4. Blow out any trapped dust or debris from inside the plug wells using compressed air before removing old units.
5. Loosen and extract the old spark plugs counter-clockwise using a proper magnetic 14mm 12-Point (Bi-Hex) thin-wall spark plug socket (do not attempt to open with a standard 6-Point socket).
6. Hand-thread the new HONDA OEM SPARK PLUG 12290-6A0-A01 (4PCS) plug clockwise to prevent cross-threading, then torque to exactly 15–20 Nm (do not over-tighten).
7. Reinstall the ignition coils, torque the mounting bolts, reconnect the harness clips, start the vehicle, and check for a smooth idle line.

Vehicle Applications:

Alternative Interchanges (Cross Reference):

This premium high-performance ignition component replaces and maps with the following target specifications:

• Honda Factory OEM: 12290-6A0-A01 / 122906A0A01

• NGK Production Code: DILKAR8P8SY / Stock Code 92411 (Laser Iridium Original Unit)

Note: Fitment depends entirely on your engine spec. This plug is strictly optimized for newer generation Honda 1.5L / 2.0L VTEC Turbo direct-injection motors and will not map with older generation naturally aspirated blocks. Please check your manual or share your chassis code with us to confirm fitment before ordering.

Maintenance Tip from Oil House Bangladesh:

Next-generation Honda direct-injection Earth Dreams turbo engines manage precise combustion intervals under immense compression, making clean flame kernel stability vital. In the demanding stop-and-go gridlocks and variable fuel quality ecosystems across Bangladesh, forced-induction spark gaps erode faster than naturally aspirated blocks. To eliminate performance loss, protect your high-tension ignition coils from premature failure, and maximize turbo efficiency, we strongly recommend replacing your HONDA OEM SPARK PLUG 12290-6A0-A01 (4PCS) every 40,000 km to 50,000 km when operating in local conditions. Always verify that your spark plug tube wells are dry and free from any valve cover gasket leaks during regular checking points.
