Tk 9,300.00

Unlock the "Maximum Ignition Power" of your engine with the world’s most durable and efficient spark plug technology.

Worn-out spark plugs cause engine misfires, poor acceleration, and heavy fuel consumption. The DENSO Iridium Long Life (FK16HR-A8) is designed to restore your car's factory performance and maintain it for over 100,000 kilometers.

Benefits:

Unbeatable Durability: Featuring a 0.6mm Iridium center electrode and a Platinum ground electrode, this plug is built to last significantly longer than standard copper or platinum plugs.

Enhanced Fuel Economy: Superior ignitability allows for a leaner burn, ensuring every drop of fuel is converted into power, saving you money at the pump.

Rapid Cold Starts: The ultra-fine Iridium tip requires lower voltage to spark, providing quick and reliable engine starts even in humid or cold conditions.

✅ Stable Idling & Response: Eliminates engine hesitation and rough idling, giving you a smooth, responsive throttle feel across all RPM ranges.

OEM Quality Assurance: Made in Japan and the USA, these are the exact plugs trusted by top automotive manufacturers for high-performance engines.

How To Use:

Inspect: Ensure your engine is cool and remove the ignition coils to access the old plugs.

Install: Thread the new DENSO Iridium plugs in by hand first to avoid cross-threading, then tighten to the manufacturer's torque spec.

Ignite: Reconnect your coils and feel the immediate improvement in engine smoothness and power.

The DENSO FK16HR-A8 is the gold standard for long-term engine health and efficiency.
