DB9 Ignition coil packs, 2 or 3 Pin??

[Ken Figenus]

Is that cost not very close to the AM OE price mate?

The 3-pin coil packs are very costly, it would be good to find a cheap replacement for the 3-pin types.

If you do find a good alternative please post it in my sticky called Aston Martin Alternative Parts.

Update -

For anyone who is doing this job I have some further info.

The ignition coil packs from eurocar parts are identical to the 2-pin DB9 ones (Thanks Mcgurk for sending me a used coil) they are from a 2002 Jag S-type 3.0L, all you need to do is to reuse the rubber boot & spring, link -

http://www.eurocarparts.com/ecp/c/Jaguar_S+Type_3....

They retail for £27 but almost every week they have a 30% off sale so I got all my 12 coils for £240.

The PCV valves, thanks to Steve from the Aston Martin DB9 1936 blog gave me a link to Amazon (US) for 2 sets, they are Motorcraft Ford parts EV-152D, link -

The total cost for them are £27 including shipping and taxes.

So my total parts spend for this job is -

12 NGK sparkplugs - £50
Genuine AM inlet manifold gaskets - £200
12 Ignition coil packs £240
2 Genuine AM Throttle body rubber O-rings £6.50
Complete set of O-rings for the fuel injectors £40 (from Mr injector uk)
2 sets of PCV Valves (Motorcraft Ford) £28.

Total is £564.50, I'm going to do this job next month, If all these parts were brought from AM they would cost £1150 so roughly a saving of £600.

Do you know if the DB9 Plugs you bought fit a 2009 V12 Vantage manual? If so where did you get them from and what is there model number please?

Hi Lee, I think your car will most likely have 3-pin coils.

As my car has 2-pin coils i can get NGK for £12 each now but unfortunately I don't know where you can get cheap 3-pin coils from if at all.

Ahh right that's for the coils but what about the spark plugs themselves? Do you know if the NGK's you bought will fit the early V12 manuals? Cheapest ive seen are Aston branded ones @ £72 for pack of 4 !! I know they are just rebranded NGK's?

I would contact Mike at Bamford Rose, he was at AM and was involved in the development of the V12V, he'll know if there are any cheap alternative sparkplugs for your car.

Hi all, I replaced my coils and plugs last year. As my car was an early 2005 model, I was expecting it to have 2 pin coils, and I was going to follow paulrog1's route and buy the Jag coils.
As it turns out, my were 3 pin and I failed to find a quality alternative. Personally I don't think it would be a good idea to fit cheap Unbranded coils to your car.
If it was a 4 cylinder engine with quick and easy replacement, I would give them a go. But the amount of work and cost to replace a duff one, I don't think is worth it. Not to mention the ramifications of a misfire, with the chance of your engine eating your cat.
I must admit, it did hurt knowing I was paying £70 for a £20 coil though.

No where near as the oem 3 pin ones are listed at about 80 gbp each ie 960 pounds whereas the Surefire ones are 599 GBP I am wondering if anyone has used them.

A saving of 400 GBP is a help.

I have emailed BR 3 times now regarding various questions however no reply. Are they prone to ignore out of country/international people.
I was/am interested in their primary cat delete headers. Not impressed.
