Is Denso better than NGK?

Is Denso better than NGK?

It is difficult to rule out a winner in the Denso debate against NGK, as both are iridium spark plugs and offer almost similar performance. 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.

Are Denso iridium spark plugs 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 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.

How long do Denso iridium 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.

How long do DENSO ignition coils last?

For the 3.4L you can get an oem Denso set of 3 from rockauto for $32.79. They could last a million miles or more like a lot of sealed electrical components. But one could fail at any time. Also but…

How long do NGK Iridium plugs last?

40-50k miles
NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor.

How often should NGK iridium spark plugs be changed?

Therefore, NGK gives them a life expectancy of 40-50k miles and Denso assigns a recommended replacement interval of 30k miles.

How long do NGK standard spark plugs last?

Is Denso iridium IX better than ngk?

If the price is your main concern, the NGK Iridium IX is cheaper than the Denso Iridium TT, although not by much. If you swap the stock iridium NGK plugs with Denso spark plugs, you might notice no difference in engine performance, especially if the manufacturer recommends both brands.

Are NGK spark plugs better than Denso?

But the most compelling reason why NGK has an edge over Denso is availability. It is easier to source NGK spark plugs (for any type of vehicle) at online shops and retail stores compared to Denso. And if you have a Japanese car, the vehicle will most likely be equipped with NGK spark plugs.

What is the difference between dendenso and NGK?

Denso is also from Japan, but NGK is a universal brand of spark plug and is renowned all over the world. The NGK Iridium IX is a spark plug designed to offer lasting ignitability, superior anti-fouling characteristics, and sharper throttle response.

Can you change the spark plugs on a Denso iridium?

Again, the answer will depend on the type of vehicle. If the manufacturer recommends Denso Iridium TT plugs, it means the motor is calibrated for the Iridium TT. Installing a different type of iridium spark plug may not produce noticeable losses in performance, but it may affect engine tolerances upon extended use.
