HONDA OEM SPARK PLUG 12290-5PA-A01 (4PCS)

HONDA OEM 12290-5PA-A01 – Genuine Made in Japan Laser Iridium Ignition Protection for High-Boost Platforms

For premium Japanese turbocharged sedan, coupe, and sports platform owners who refuse to compromise on combustion safety, immediate throttle transitions, and consistent fuel tracking parameters, the HONDA OEM SPARK PLUG 12290-5PA-A01 (4PCS) provides professional-grade ignition mechanics. Co-developed by NGK as the definitive factory benchmark specification for Honda’s modern high-output turbo units, this premium Laser Iridium series features a cold Heat Range 8 layout. It is custom-tailored to combat the aggressive internal thermal stress and immense cylinder pressures of forced-induction engines, completely eliminating high-voltage ignition spark blowout paths under maximum boost limits.

Key Features of HONDA OEM SPARK PLUG 12290-5PA-A01 (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.
• NGK ILZKAR8J8SY Production Specification: Built with a specialized high-ignitability dual-precious metal composition, featuring a fine-wire Laser Iridium center core and a targeted Platinum mass pad on the ground electrode to fully arrest gap degradation.
• Cold Heat Range 8 Stability: Engineered as a dedicated cold-type spark plug to rapidly move excess thermal energy away from the combustion boundaries, actively preventing catastrophic pre-ignition and engine knocking anomalies.
• Anti-Seize Plating Treatment: Finished with machine-rolled precision threads and a specialized trivalent metal shell barrier that isolates moisture, blocks cylinder head thread seizure, and secures safe extraction steps.

Why Choose HONDA OEM SPARK PLUG 12290-5PA-A01 (4PCS)?

The dense traffic gridlocks, high ambient humidity, and fuel composition variances found within Bangladesh throw massive thermal strain at modern direct-injected high-boost platforms. In systems like the Civic Si or CR-V Turbo running precision tunes, generic or wrong heat range specifications cause fast carbon fouling, leading to sudden engine jerking, sluggish throttle transitions, or permanent engine knock damage. The HONDA OEM SPARK PLUG 12290-5PA-A01 (4PCS) available at Oil House Bangladesh delivers an authentic, rock-solid shield for your vehicle, keeping your performance curve seamless, crisp, and fully responsive.

Application Instructions

1. Shut off the vehicle engine on level ground, apply the parking brake, and let the motor cool down entirely.
2. Carefully detach the upper engine plastic vanity 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 12290-5PA-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 engine idle line.

Note: Fitment depends entirely on your engine block design and factory chassis specification guidelines. This plug is strictly optimized for modern Honda 1.5L / 2.0L VTEC Turbo high-output direct-injection motors and will not map with conventional naturally aspirated blocks. 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:

High-boost direct-injection platforms like Honda’s VTEC Turbo architectures generate extreme internal chamber temperatures, causing the fine spark plug gap intervals to wear and erode faster than conventional naturally aspirated blocks. Given the demanding stop-and-go congestion and variable fuel octane volatilities found across Bangladesh, keeping an optimal spark clearance is critical to prevent destructive spark blowout and ignition stutter. To preserve your engine’s ultra-crisp throttle mapping lines, protect the high-tension ignition coil packs from early failure, and keep your boost curves flat, we highly recommend inspecting and refreshing your HONDA OEM SPARK PLUG 12290-5PA-A01 (4PCS) between 40,000 km to 50,000 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.
