What is the difference between BKR5e and BKR6e?

the difference between a BKR6e and a BKR5e is that the 6 is a colder plug. On NGK the higher the number the colder the plug. A 5 would work to get you out of the woods.

What happens if you use a hotter spark plug?

A “hot” spark plug has a longer insulator that prevents heat transfer into the water jackets. It keeps more heat in the tip of the spark plug, which helps burn off combustion chamber deposits. But if there’s too much retained heat, the engine will experience preignition.

Should I use a hotter spark plug?

Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean may contribute to pre-ignition or detonation. If not running an electronic engine management system, it pays to tune slightly on the rich side to avoid detonation.

Which type of spark plug is best?

NGK 6619 Iridium IX Spark Plugs snagged the top pick in our spark plug comparison because they offered the best mix of high-performance, fuel efficiency, durability, and dependability. Featuring an iridium construction, these high-quality spark plugs provide a longer lifespan than copper and platinum spark plugs.

Which NGK spark plug is the best?

What is the most powerful spark plug?

Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.

What does R mean in NGK spark plugs?

[R] Resistor – If an R is present, this indicates a resistor type spark plug. Resistor type spark plugs reduce the amount of radio frequency interference (RFI) that can cause ignition misfires and static on the radio.

Are NGK spark plugs any good?

What are the electrodes of a NGK spark plug?

NGK V-Power Spark Plug (BKR6E) Center Electrode Core Material: Copper Core Center Electrode Tip Material: Nickel w/ V-groove Electrode Core Material: nickel with V groove Electrode Tip Material: nickel with V groove Gap Size: 0.032 in

What kind of spark plugs for a BMW 540i?

I ordered NGK 6962 BKR6E spark plugs for my 1997 bmw 540i since our local part store only had bosch+4 and AC delco. The car starts stronger and idles smoother now.

Which is the best spark plug for your car?

The car starts stronger and idles smoother now. Standard spark plugs like these NGK’s work great, but they don’t last as long as iridium or platinum spark plugs ( est 20,000 30,000 miles less). Choosing NGK means all your new spark plugs will work the same and fit properly.

Can a platinum spark plug be used in a race car?

You won’t see a platinum plug on ANY race car application, but all senior cars (Caddies, Lincolns and Buicks) use them extensively. There is no need to put $15 spark plugs in a 20 year old car that had “old school” spark plugs that today sell for a buck or two at the local auto supply store or big box discount store.
