Are DENSO spark plugs any good?
Are DENSO spark plugs any good?
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 Denso plugs shrinks more than an NGK. For this reason, Denso plugs do not last longer than NGK units, but they are better at producing powerful sparks.

How can you tell if a DENSO Spark Plug is real?
A genuine DENSO spark plug should have a uniform insulator shape, be white in colour, and the width of the ground electrode should be consistent. Poor quality welding is something to look out for, while spark plugs with ground electrode chips made from poorer materials should also be avoided.
How long do DENSO spark plugs last?
120,000 miles
All Denso long life iridium spark plugs are an OEM design, made for a specific engine. Some feature a special resistor or electrode design, depending on the OE requirements. In their OE application, Denso’s long life plugs can last up to 120,000 miles.
Do expensive spark plugs make a difference?
High performance Noble metal plugs can perform consistently and well, which helps to maintain the engineered performance of the engine. They won’t make the engine perform better than it did when it was new, but they will help it stay at that level longer.
What’s the best spark plug for performance?
Four Different types of spark plugs: Iridium – Often considered to be the best spark plugs for high performance and longevity. Iridium usually lasts 25% longer than platinum, but you guessed it, they’re usually more expensive!
Are Denso Iridium spark plugs pre gapped?
DENSO spark plugs are manufactured with a pre-set gap. Do not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged.
Are Denso spark plugs made in China?
All DENSO Spark Plugs are manufactured in Japan, Indonesia, China and USA. If a part claims to be a DENSO component but has been manufactured outside of these areas, then it is not genuine. Always check, and if in doubt, call your local DENSO representative who can advise.
Are NGK spark plugs Made in Japan?
NGK is a manufacturing company based out of Nagoya, Japan. The NGK Spark Plug manufacturing plant opened in Sissonville, West Virginia, in 1995. The Sissonville plant now produces oxygen sensors and spark plugs for internal combustion engines, along with ceramics and applicable products.
What are signs of a bad spark plug?
What are the signs your Spark Plugs are failing?
- Engine has a rough idle. If your Spark Plugs are failing your engine will sound rough and jittery when running at idle.
- Trouble starting. Car won’t start and you’re late for work… Flat battery?
- Engine misfiring.
- Engine surging.
- High fuel consumption.
- Lack of acceleration.
What is the longest lasting spark plug?
iridium spark plugs
Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency.
What are the most fuel efficient spark plugs?
DENSO Corporation will launch a fuel-efficient spark plug in the Japanese market on January 6, 2010. DENSO’s new spark plug improves fuel efficiency by 1.2 percent, torque by 1.1 percent, and decreases carbon dioxide emissions by 0.8 percent*1 in comparison with the company’s conventional nickel spark plug.
Which is better an iridium or platinum spark plug?
Platinum spark plug is a ‘golden mean’ between copper and iridium ones. Platinum has twice better longevity than copper and fairy low price. Platinum disc and central electrode tip provide slow wear rate and better fuel efficiency.
Is NGK or Denso better?
The NGKs, IMO, are better plugs than Denso. Get the NGK Laser Iridium. This 0.7mm iridum tipped plug has a platinum ground pad and should last the 120K mile spec’ed interval. The IK20 however, is just a regular shorter life plug without the ground pad. You’ll get less iridium and less platinum than NGKs in general.
What is the difference between spark plugs and glow plugs?
Glow plugs glow releasing high amount of heat. Spark plugs release spark which is the jumping of electric current in the air gap between the two electrodes of a spark plug! Glow plugs are used in diesel engines whereas spark plugs are used in gasoline engines.
