Denso Iridium

[okl]

yo, just wanna ask how far can the denso iridium spark plug last?

 

my friend who drives a car says the iridium can last up to 100,000km, his car is a good example, as he said, it still hasnt lost 'power' yet.

 

so i just wanna clarify how 'far' can the denso iridium spark plug go?

 

also, my friend also said that denso plugs are more for toyota cars and that my bike, being a honda, should use the ngk iridium instead.

 

comments pls!

 

thanks!

I use my NGK Iridium on my VFR800 for 40000km over 2 years, cleaning and checking it twice over this period. I am sure it can still be used but I suffered increased fuel consumption near the last 10000km. My previous Denso also lasted 40000km. I prefer the Denso over the NGK as it seems to be more robust, but NGK is cheaper at $13per vs $16 for Denso.

Stock plugs for your 929 are Denso Iridiums. I usually change them every 25,000km, or when I do valve clearance checks.

Hi vfrT.

 

Just wondering how does one clean and check spark plugs?

 

What do I need to do this and how do I go about doing it. Appreciate you advice. Tks a million!

You do this by using a brass wirebrush on the plugs, it should take away most carbon deposits. Then proceed to check the spark gap with a feeler gauge (thin metal sheets of precise thickness) to ensure it is within manual specs.

Use a light brass wire to GENTLY remove built up carbon. NGK and Denso say NOT to re-set the gap as they are factory set. Listen to them.

 

This is because the iridium tip is very hard & brittle and can break easily if you try to insert a too wide feeler between the tip and the ground- I learn the hard way.

 

If you really must get at the gap for whatever reason, be very GENTLE.

 

To get at the space/gap between the insulator cone and the thread body, I use a thin strip of emery paper that will fit between the gap and gently rub off the carbon. Blow out any loose carbon after that and clean up with a clean rag with a shot of WD40.

 

As for checking, there are many links that teaches you how to read your plugs - they can explain it better. This is one of such links http://www.nightrider.com/biketech/spkplghnbook.htm#We
