We are a professional wholesale supplier of genuine DENSO spark plugs, offering a complete range of DENSO iridium spark plugs for gasoline and gas engines worldwide.
From standard nickel plugs to high-performance DENSO Iridium TT and DENSO Iridium Power series, every DENSO spark plug we provide is engineered to match the exact ignition requirements of the engine, delivering reliable cold starts, stable idle, and maximum combustion efficiency.
Our DENSO Iridium TT spark plug features a unique twin-tip design — with an iridium center electrode and a platinum ground electrode — achieving superior ignitability, lower required voltage, and more complete combustion.
The result: reduced fuel consumption, lower emissions, and extended service intervals that benefit both your customers and the environment.
For engines operating under high load or extreme conditions, the DENSO Iridium Power spark plug offers enhanced durability.
It uses a specially formulated iridium alloy with a high melting point and exceptional wear resistance, providing a service life of up to 120,000 km under normal driving conditions while maintaining consistent spark performance.
Every DENSO automotive spark plug in our inventory is manufactured to precise OEM specifications.
Thread diameter, reach, heat range, and electrode gap are all optimized for specific engine families — including the Toyota 1ZR, 2ZR, 3ZR, 2TR, 1KD, 2KD series and many more.
The anti-seize coating and precision-welded electrodes ensure easy installation and long, trouble-free operation.
We understand that finding the right plug can be a challenge. That is why, beyond just supplying DENSO spark plugs, we support our customers with accurate spark plug number cross reference and detailed spark plug torque specs — ensuring correct matching and safe installation every time.
