HiVehicle iridium spark plug uses the precious metal-iridium with high temperature resistance, ablation resistance and excellent oxidation resistance. The diameter of the ignition end of the center electrode is close to 0.6MM, the ignition is stronger, the combustion is cleaner, the fuel saving is obvious, and it has a strong anti-interference effect, and the service life is 3-5 times that of a general spark plug.

Iridium Tip-Better than OE

360° continuous laser welded center electrode create reliable resistance to thermal shock occurred in new generation engines.

0.6mm Ultra fine wire iridium center electrode provide better ignitability

Embedded Copper Core

Copper cored center electrode has better heat dissipation, dissipate a lot of heat as quickly as possible to prevent overheating of spark plug firing end and engine damage.

Resistance powder

Glass sealant with resistors ensure conductivity and sealing property,provide protection from radio interference too.

Ceramic Insulator

Newly developed high performance ceramic T95 with excellent insulation, heat resistance and thermal conductivity required by spark plugs.It ensures outstanding dielectric mechanical strength of insulator.

Analysis of the Cause for Abmormal Combustion

spark plugs

The proper servcing of spark plugs can help make the differnce in good engine performance and fuel economy.

An engine with adequate compression and proper fuel/air mixture may fail to properly ignite the fuel charge in one or more serveral ways,depending on the condiction of the spark plugs.

Misfire could be caused by improper fuel/air mixture in the cylinder.

However,the problem is more comonly caused by faulty ignition.

NOT QUALITY, VERY CHEAPLY MADE
I purchased these for a 2005 Chevrolet Silverado 1500 (was listed as a part that fits) as soon as I received them and saw the iridium spark pin I thought it was unusually small and thin, I went to my local parts store and compared to an OEM spark plug, the spark plug on the right is the OEM plug the one on the left is this plug. If you are looking at getting these plugs for a large vehicle I highly recommend that you stick with OEM not these, these may work for a small sedan vehicle but even then it's risky. I doubt these would last even 10,000 miles on a small car, they might be cheap up front but sometimes you really do pay for what you get. Absolutely will be returning these.
