My car started pinking again.....
 

Previously it was due to cheapo lambda's fitted, a change to new genuine ones sorted that. On my way back from Devon recently it started pinking a little on part light throttle. Before going down the compression / leak down test for HG issues I thought I'd take a look at changing the coils and plugs. In short there was a mixture of old bremi and 1 new bosch coils so I changed them all for new bosch ones (£17ea ebay). The plugs were well worn ngk dual electrode ones so I changed them for a full set of ngk iridium ones (£38 per set ebay).
The car now starts and idles so much smoother, unbelievably more I'd say. It's super smooth on the road too. It's not been this smooth to drive since I bought it. NO pinking either :supz:

Just a pointer if anyone else is or does in the future experience slight pinking, MAYBE try this first :-D

Well done Sir :thumbs: Could U forward the eBay link to the NGK spark plugs please.

DCPR8EIX plugs
 

Hi, I can't do a link off of my phone but eBay seller is driven2automotive and item number is 150781439847.
Hope that helps!
Shawn.

THANX Shawn :thumbs: The item number is good: http://www.ebay.co.uk/itm/1507814398...847%26_rdc%3D1 but which plug exactly for Cecil ? Part number ? as there's lots to choose from :smt017

DCPR8EIX are the ones you'll be wanting :thumbs:

Good man :thumbs: Ta muchly

DCPR8EKP This is the Part Number for the S54/E46 engine I got ? :119:

The NGK IX plugs are great, I've been using them for over a year. The car feels much more lively.
IIRC, they are about £40 a set, so a lot cheaper too.

The DCPR8EIX are an upgrade plug for the S54 engine over the OEM DCPR8EKP :smokin:
Here's NGK guide to confirms this: http://www.ngkpartfinder.co.uk/car_c...ra.php?id=6569
Guess who just bought a set :-D

Worth every penny! Certainly transformed mine! I fitted them to my previous std M3 too. Right I'm off out for a blat :supz:

Enjoy :smokin: and take some pix, I need proof :wink: :hahaha:

It didn't happen. A call out to 10' of original 1870's ornate cornicing detaching itself from the ceiling of a grade 1 listed property put paid to it :(

On a plus my invoice will pay for some new cups :partyman::-D

A result of sorts :smokin: just don't get your hopes up on getting your CUPs quickly or for a good price :bigcry:

Brilliant. Found this thread at the top of a search. I've ordered from the same eBay seller. Did they take long to come ? :beer:

Very quick delivery :wink:

Have a comp test anyway.

The ETA for mine (which I bought Friday pm) is this coming Tuesday :thumbs: fingers crossed ;)

I still will at some point soon, for peace of mind. I'll go to munich legends I think as they know the car, chandlers bmw Brighton said oh they all pink its normal :whistle:

:smt023

UPDATE: NGK IRIDIUM spark plugs
 

Quick update: Ordered mine last Friday afternoon and they arrived first thing this morning. Great Service from the before mentioned eBay seller :thumbs:

They look like Chinese replicas (eBay?)

You're such a pessimist sometimes Shimmy :wink: :hahaha: These are "Made in Japan" and come with 12 months warranty :thumbs:
What makes you say such things ?

All the Chinese ones say Made In Japan.....bloody clever those Chinkies

Matt,

any real benefit over oem plugs?

only need to know to satisfy inevitable desire to change them if given a wiff of any improvement.!!:-D

I'm still waiting on mine. Hopefully tomorrow.

LOL! you're a pessimist... and a wind up merchant :-D

I moved my business to ///M-L from there too, can't think of anything eloquent to say about Chandlers atm so 'bell-ends' will suffice for now...
...till I've had a few beers!

I'll tell U tomorrow mate :thumbs: Cecil's still @ Elms Cambridge... although if you read the previous posts in this thread, others have positive results with these + NGK recommend these as an upgrade over the OEM NGK R Platinum :beer:
Here's a comprehensive explanation from NGK: http://www.ngk-sparkplugs.jp/english...ium/index.html

Not that clever http://www.ngk-sparkplugs.jp/english...ake/index.html :whistle:

They certainly made a MASSIVE difference to my car but that was likely down to one or more duff original plugs or coils. Maybe you won't notice anything, maybe that occasional stumble at idle or temperamental running when in the warm up cycle will be reduced or sorted. It's just nice to know that such a highly tuned /strung engine has the best plugs out there fitted. For under £40 too :thumbs:

I'm not connected to the seller in any way either :hahaha:

Anyone got a link to coilpacks ? decided I am going to treat Cecil to some new packs & plugs

part number of coils is 12 13 1 712 219 @ £39.52 + vat each (BMW genuine parts)

eBay item no . 180941316637. £22.99 delivered individual was the best price I could find. I've not had any as yet though.

auto_ignition_online is the eBay seller. My item number was 181108013648. They are on for £17.95 but make an offer of £17 ea and he'll accept it. Genuine German bosch items :thumbs:

EDIT £106.99 for 6 delivered

That's the same seller as my link above. :thumbs: bargain
