I still have OEM plugs in my Vantage, but have had exposure to Denzo plugs in aircraft engines. They are the OEM choice for Rotax aircraft engines, and no person I have spoken too in the past 10 years or so has had bad things to say about the Denzo product.
In SA they are not cheap, but what is the price difference against Aston OEM plugs?

 

that's good info captain Greg ... 8 plugs $76 usd..and for all the canucks $100 cdn
half the price of oem. think i'll give them a try,

 

Seems cheap...website states for 05-07 cars
AM plugs from Rich are $ 195.00..I believe his are good for all years...

While the brand is solid check your year of car...
Good luck...

 

I was invited to the Aston Dealer to see the new 720 Mclaren later this week in Cape Town, while on the phone I asked him about Denzo plugs seems that off the record they also cant fault them.....just saying

In CT our top tech at Aston was poached from Audi R stock so the man is quite knowledgeable so I think you will find the quality great.
Then I consulted the book seems the OEM plugs are good for 75000KM and no year limit

 

Yea...during my 8 year service I was advised that if no codes received on the plugs...leave them run and alone...

I have over 30000 miles and runs great...knock on wood...lol

 

When searching before I found this little chart, I believe it was on the Denso site... I added the E3 spark plugs which match the Denso

 

I believe Aston Martin plugs are Denso, at least for the DB9's

 

They are NGK as OEM supplied. Nothing wrong with DENSO plugs.

 

Interesting, my car had Denso in it when I changed the plugs and coils. Wonder why someone changed the plugs in mine.
