FAQs

1. Do Denso spark plugs need lubricant?

As a result, the plug may become loose due to vibrations. Due to this, DENSO recommends that you do not use thread lubricants. A small amount of grease may be required in some exceptional cases (such as on some LPG-powered forklifts). Pre-lubricated spark plugs are provided in such cases.

2. Do I need to put anti-seize on spark plugs?

Due to the nickel coating on most modern spark plugs, anti-seize has become less important in spark plug installations as a result of improved protection against seizing in aluminum cylinder heads. Using anti-seize can increase breakage risk by 20% by altering the tightening torque.

3. Do all vehicles use anti-seize on spark plug threads?

A nickel or zinc-chromate shell plating is now found on virtually all spark plugs. In essence, the plating is a substitute for thread compound or copper slip. It is not recommended for use when installing new spark plugs by most spark plug manufacturers.

4. Does WD-40 work as anti-seize?

No. Rusted parts can be removed with WD-40. Anti-seize is used to prevent parts from rusting together.

5. Are Denso spark plugs the same as NGK?

Denso Iridium spark plugs use a much thinner electrode than even the NGK. Given how long the NGK electrodes last you could argue the NGK are over-engineered and reducing their diameter would have no effect on their service life.

6. What is the difference between a Denso plug and a normal plug?

DENSO TT Spark Plugs provide greater ignitability than platinum spark plugs, and their hardened ground electrode is more resistant to temperature and electrical erosion than standard nickel plugs. This makes the use of TT in LPG engines highly effective for an affordable price.

7. Is DENSO a German company?

Established in 1984 in Munich, in southern Germany DENSO now has its primary locations in Eching, an industrial area in northern Munich, and in Wegberg near Aachen.
