DENSO Iridium Power Spark Plugs

[oilman]

We are looking at stocking these quality spark plugs in the future.

I am interested in any opinions that forum Members here may have on them.

So, what's your opinion on them?
Are they good?
What sort of price would be attractive for a set of 4?

Thanks in advance for any feedback that you have.

Cheers
Guy

Just had a set fitted this weekend when I had my GTiR serviced

Along with the Silkolene Oil THANKS 8)


They seem fine so far


Price wise I paid about £45 delivered. I will dig the receipt out when I get home later

Had a set in mine for about 8-9months,i paid £38 from my local motor factors The only problem i had was that after normal tightening(when you have been fitting plugs since you were 9 you get a feel for it )they tended to come loose and cause overfueling :shock: This happened 4 times,each time i tightened them down a little more :shock: In the end i spoke to a mate of mine that preps rally cars and he said to tighten them as far as i dare :shock: :shock: :shock: which was all the way and a bit more,this has seemed to do the trick To be honest i wont be useing them again because of this fact

The denso plugs are the best performing but some people prefer the NGK that has a longer life.

You're good and competitive for oil so to stay the same on the plugs you need to look at Sub £40.

At that and from previous experience with your company I'd have a set.

Good luck,
Jim.

Several people on the 2 owners club have had problem with the electrodes breaking off and mashing the piston crowns and head.

I no longer use Iridium plugs, a set of copper plugs changed at every oil change do just as gooda job, and only cost a couple of quid each.

Iv used denso's on both my last car (200sx) and now my pulsar and have never had 1 problem with them, i get them for a good price being in the trade but i think around the £40 mark is about right.
