CHAMPION SPARK PLUG N3C – EQUIVALENT TO B8ES.
Iridium Spark Plugs – Service Life

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.

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.
Champion N2C NON – RESISTOR spark plug equivalent to NGK B8ES.
A BPR5ES spark plug is hotter and better suited for high-speed or heavy-load applications than a BPR6ES spark plug, which is cooler and better suited for low-speed or light-load applications. This is the major difference between the two BPRES spark plugs.
At the top of the list, we have the NGK Spark Plugs. With iridium as its core material, this spark plug pack can operate at a much wider heat range as compared to ordinary spark plugs made out of platinum or copper.
Following an acquisition by Cooper Industries

In 1989, Champion was purchased by Cooper Industries and is now a wholly owned brand of Federal-Mogul Corporation. Its main products are a line of spark plugs for a wide range of cars, trucks, SUVs, racing, and marine applications.

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.
NGK doesn`t recommend adjusting the plug gap more than . 008″ in either direction. Beyond that slight adjustment, the ground electrode and center electrode won`t align properly, hindering spark plug performance and drastically reducing plug life.
Champion RN3C RESISTOR spark plug equivalent to NGK BR7ES. Suited for road use. This is the ideal plug for any tuned Lambretta.
CHAMPION SPARK PLUG N2C – EQUIVALENT TO BR9ES.
Additionally, iridium is complex to extract from its ore, and the resultant metal is brittle and difficult to work with. All these factors increase the relative cost of iridium spark plugs.
Platinum has better performance in terms of durability than other standard spark plugs. However, when compared with iridium, there`s a major difference. Iridium has better performance in igniting the air-fuel compression within the combustion chamber.
On top of that, the electrical resistance of iridium is better than copper, which also adds to its performance and longevity. The iridium plugs might cost slightly more than the copper spark plugs, but it`s still worth it because you`ll be paying for quality.
NGK builds two types of iridium spark plugs: OE Iridium and Iridium IX®. Every plug in the Laser Series was designed for an OEM application. All dual precious metal plugs are designed to provide maximum longevity.
Platinum is much harder, with a higher melting point than nickel alloy. This allows a platinum spark plug to retain a sharp edge (and resist wear) much longer. Longevity is a key advantage in platinum spark plugs — they`re typically replaced around 60,000 miles but can last up to 100,000 miles.
In general, a light tan/gray color tells you that the spark plug is operating at optimum temperature and that the engine is in good condition.

Turned poulan pro 42 inch 18.5 HP Briggs and Stratton mower off after 1hr of use to move a board I was about to mow over. Tried to restart it but it just backfires. Removed spark plug and it looked fouled. Cleaned it up but when looking at spark it is orange in color. Bought new spark plug and now get white spark. Installed new spark plug and it still backfires. Plug is wet with gas. Any suggestions?
ANSWER : Check the valve clearances and especially the inlet valve to make sure that it is not riding (staying slightly open) B&S are notorious for valve problems as most of their motors do not have a valve adjustment on them, the valves stems have to be filed/ground down to get a clearance. Somewhere between 0.010 to 0.015″ is near enough for the inlets and about 0.005″ more for the exhaust. It is not critical.

Spark plug wire boot grounding out on coil, 96 outback 2.5 automatic, just put new spark plug wires, new spark plugs, and new coil on. ran great for two weeks, now spark is jumping out of boot at coil on one wire, put old coil back on and still does it in the same spot. replaced wires again, and still does it in the same spot. seems to do it only under a load. Is my new spark plug on that cylinder bad? Does the coil need some insulation under it? It is the coil that sits right on top of the motor. Any ideas? thanks.
ANSWER : Sparks are high voltage, and will always follow the path of least resistance. If you can visibly see a spark (whether in a lighted area, or in the dark), that means either that a plug wire (or coil wire) is open (non conductive), or your have a carbon track on the surface where the spark can be seen, but most likely you have BOTH problems!

If you have an ohmmeter, check the resistance of each wire involved, particularly spark plug wires … which means you must be able to connect to both ends of each wire at the same, and hopefully, FLEX those wires, to be sure they don’t have a break inside that is intermittent (comes and goes)!

I just purchased this Yamaha boat w/Twin MR-1 140hp motors, less than 100hrs (60 prox)and the starboard motor only reached 8000rpm on a 10000 redline spec (the port motor reaches 10000rpm. I have replaced the spark plugs immediatly and now the motor reaches 9500rpm. When the plugs were replaced the plug wire top of the plugs had a black powder residue (like graphite)and #1 & 4 plug electrode end were black minimal soot and #2 & #3 had a white color residue on the ceramic.

Any suggestions to attain the full 10000rpm?

A Yamaha dealer is 100 miles, so I would like to fix myself if possible. Thanks

ANSWER : I never rec’d an answer…..I WANT A REFUND!

No spark to spark plug
ANSWER : Try checking the coil

Spark plug gap setting for 92 benz 300e 4matic
ANSWER : Look at sticker unda da hood

What is the spark plug gap size for a 2000 kia sephia?
ANSWER : The gap size is .044 for a Platinum tipped plug in a 2000 Kia Sephia but if You are using E3 Plugs, You have NO Gap to set. It’s a 360 degree firing plug that You install and forget about.

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.
ANSWER : Every sympton you are describing here can be attributed to fuel starvation due to blocked jets and or water in carbs, when your engine dies does it die with dry plugs, or wet oily ones?
