Denso IK20 Iridium Power Spark Review

I use Denso Iridiums in all my cars and even my self propelled mower (Honda). Do not be fooled by the so-called three-pin plugs, which, by the way, are completely wrong according to the laws of electronics. A single smaller tip produces a larger core of flame with a larger dispersion pattern, similar to how a small 1" tweeter delivers greater dispersion than a 3 or 4" tweeter. Facts don't lie like advertisements.

Perfect for my 2013 Honda Fit. dbl - checks the part number on the Denso website. Took me a few hours to do it myself, you have to pull the hood to access the connectors on the side of the engine bulkhead. Very simple, I found a video on YouTube. The 86,000-mile NGK electrodes were 1-1.25mm worn, quite a gap compared to the new Densos. Let's see if I can get an improvement in MPG.

Replaces Bosch Iridium spark plugs. Walked right in without having to adjust the spacing. you are doing great work There are no instructions saying the gap is already set and they say the 0.4mm hides a very narrow gap. This is a kind of red herring since we are not talking about the gap, we are talking about the diameter of the electrode. Had to look at their website to find out, coupled with measuring the gap with a gap tool.

Great for the price. I bought a new (used) 2004 Audi A4 and put new candles in it. Idle was rough before install, that helped. Easy installation if you've done stubs before. Remember to apply dielectric grease to the top of the connector to prevent sparking and ensure reliable conduction, and apply anti-seize compound to the threads for easy removal later! Use a torque wrench to properly tighten the connector. Very happy with these forks and although this was my first purchase from this brand I

After 100,000 miles my Toyota Tundra started misfiring due to cracked coils above the spark plugs which had to be replaced. To make sure the misfires are fixed I figured it would be better to change the spark plugs as well. I have searched the internet for iridium spark plugs and found that they are the cheapest around. I always bought a cheap carbon electrode type before reading about iridium plugs and decided to make milkweed and pay extra money for this spark plug upgrade. I'm so glad I did!
