In brief, ignition coils are in the making for turning small amounts of current into large ones. This large amount of current is then used by the spark plugs, which give the maximum effort to ignite the fuel. Then, the engine of your car starts up. In this case, misfires might happen.

Denso is one of the best brands of automotive parts. They provide overall great quality, durable ignition coils. Moreover, DENSO was the first brand to create compact stick-type ignition coils which is a great convenience. Because of its small size and thin shape, it saves a lot of space. With the help of some innovation, it does not need any high-tension ignition cable either. Fitting and installation are easy to do as they fit perfectly into their place. Moreover, it has DENSO micro-sized driver circuits and diagonal inductive winding, which helps produce the highest amount of power possible. Famous automotive vehicle manufacturers and DENSO have been also partnering up to create the best and most compatible products. Regardless of the type of configuration, all the products are made with expertise.

 They are made with specific applications and then special engineers improve the product along the way. The products overall are consistent and smooth and give you the best product for the price. Also, DENSO products generally come at middle to high prices and also give the best quality. 

Features of DENSO Ignition Coil


As for the design, these ignition coils are made from the best materials possible for an ignition coil. Though, surprisingly the prices stay flat. The Denso Ignition coils are divided into 4 main parts. The first part is the compact driving circuit, which helps in making out the most amount of power possible. Superior quality components and materials help the ignition coils last much longer, and they are also tested and inspected. The diagonal windings on the ignition coils help a lot when reducing Bobbins, Size, and weight. Overall, the design and build make up a light and small ignition coil that can create a strong and powerful product.

Coil Efficiency

In brief, the DENSO ignition coils have efficiently built-in coils that perform most of the work. The cylindrical top also removes the need to generate high voltage. Instead, the work is done smoothly and easily without wasting much power. This also helps in reducing misfiring in the ignition coils, which is always a hassle to deal with. It also eliminates the need to use high-tension ignition wires. In general terms, high-tension cables or spark plug wires are lead wires which are also called HT leads. These connect the distributor, and ignition coils in each spark plug together. These are needed in some types of engines. So, in the case of DENSO ignition coils, these are not needed.


In the case of every product, the price of it matters a lot. Moreover, it also determines how the quality of the product will be. Budgeting is also another factor to look into. In the case of Ignition coils, there is a wide window of prices. For 8-piece packs of ignition coils, they can come anywhere from 100 to 220 US dollars. For better quality ones, they come in at 140 or more US dollars. For comparison, Bosch 6-piece ignition coils are about 140 US Dollars. This means a piece comes in at about 30 US dollars, though dealerships will charge more.

For AC Delco, 6 pieces come in at about 170 US dollars, and logically, each comes at about 35 US dollars. At dealerships, they might go into the 50-dollar region. For DENSO ignition coils, the 6-pack set comes in at about 132 US dollars. Individually, they come in at about 52 US dollars at dealerships. For the quality, this price is more than acceptable. 

Durability, Compatibility, and temperature control 

In the case of durability, the ignition plugs depend on their use and build quality. Generally, the ignition coils can go anywhere from 80000 to 120000 miles before needing a change. In the case of DENSO ignition coils, these can go about 100,000 miles before needing a change. In time calculation, it can go for about 2 years or more before needing a change or repair in your ignition system. 

Compatibility also plays a huge part in buying ignition coils. In the case of DENSO ignition coils,  they are directly partnering with many automotive manufacturers. For example, they have been making ignition coils to fit directly into Toyota vehicles. The Toyota Land Cruiser is 4.7L, and the 2002 Toyota Tundra is 4.7L, and such vehicles are great for the DENSO ignition coils. 

Generally, ignition coils do not have any problems with changes in weather. They fit into a part where heat is common. Though, some ignition coils have trouble and misfire in some colder weather.  Because of the great overall build quality of the DENSO ignition coils, they do not have any problems in any weather variations.
