What do NGK Spark Plug numbers mean?

What do NGK Spark Plug numbers mean?

The heat rating is a measure of the amount of heat dissipation. The heat range of a spark plug is the range in which the plug works well thermally. The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.

Which NGK plug is hotter?

NGK plugs are colder the higher the number, hotter the lower the number. Starting with part # BKR6E-11 (heat range 6), a colder plug would # BKR7E-11 (heat range 7), a hotter plug would be # BKR5E-11 (heat range 5). For NGK Racing Plugs, the heat range is located AFTER the hyphen.

What is the difference between NGK BPR5ES and BPR6ES?

BPRxES is an NGK part number (which makes sense, Honda contracts out their “factory” plugs to NGK). The BPR5ES will run hotter than the BPR6ES. Running a BPR6ES in an engine designed for a BPR5ES may cause premature fouling, and running a BPR5ES in an engine designed for a BPR6ES may cause detonation.

Are NGK Spark Plugs better than champion?

I have had great luck with Champion but the mechanics on our local automotive radio show say NGK are the best plugs, and you are always in the best shape when you use the exact plug recommended by the OEM.

Which is better Denso Iridium or NGK Iridium?

Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in these plugs shrinks more than an NGK. For this reason, Denso plugs won’t last longer than NGK units but they will be better at producing powerful sparks.

Are NGK Spark Plugs good?

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.

Which is better iridium or platinum 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.

Do spark plug brands matter?

Yes, the brand matters when it comes to performance and how long they last. No. All spark plugs are made same, whether they’re cheapest or the most expensive ones.

Are Iridium spark plugs worth the money?

So, an investment in these spark plugs would surely be worth it for this. You may never actually have these spark plugs go bad on you.

Can I replace Iridium spark plugs with platinum?

Platinum and iridium take more energy to spark, but last a long, long time. This is why most manufacturers have gone to those two for modern engines. So, in a perfect world, as long as they fit your engine, all three would work just fine. But sadly, that is not the case with modern engines.

How long do NGK Iridium plugs last?

NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ.

Can I use WD40 on spark plugs?

Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away. You can also use it to ease the removal of spark plugs, especially if there is any rust or corrosion.

Can I use WD40 to clean spark plugs?

This is because the spark plugs and wires are wet! All you need to do at this point is spray some WD40 on them, and the moisture will disappear. WD40 also avoids corrosion on spark plugs, batteries, alternators, and distributors. It removes the dust and dirt from the spark plugs.
