This decision regarding Bosch vs NGK iridium spark plugs analyzes longevity and durability. In the same breath, drivers should note that the difference between cheap spark plugs vs expensive ones is the type of spark plug material used in the center electrode and its complementary technologies. As a matter of fact, this is the main differences in spark plugs models. Notably, BMW drivers in a dilemma between BMW spark plugs NGK or Bosch should pick Bosch plugs. They should also prefer Bosch to champion spark plug.

Spark Plug Comparison E3 VS NGK Spark Plugs

The E3 and NGK spark plugs are both very popular. However, they have spark plug differences that make one brand better than the other. A driver should consider factors such as power production, durability and fuel efficiency when comparing E3 spark plugs vs NGK.

E3 spark plugs use a unique ground DiamondFIRE electrode which stimulates the formation of turbulence in the mixture of air and fuel. By doing so, it enables complete, thorough combustion. The main benefits of this technology include more power production ranging between a 3% to 6% increase, better fuel efficiency and minimum carbon emission.

NGK spark plugs use a laser-welded fine tip top-quality iridium center electrode. It performs enhanced ignition, quick throttle response and durability. This spark plug produces a steady spark that actively combats engine misfiring and challenging cold starts. NGK spark plugs are also coated in trivalent material and ribbed ceramic. These materials increase durability by preventing corrosion and seizing. Drivers should always remember this characteristic when researching on how to buy spark plugs.

Drivers wondering how long do NGK spark plugs last can find that they keep going for 100,000 miles.
