Spark Plug recomendations
 

Hi Guys,

I'd like to get some funky new spark plugs and see if it will help my poor warm starting on LPG.

The sticky has details on fitting
http://www.audipages.com/Tech_Articl...sparkplug.html

And they suggest Bosch Platinum +4 (Model number 4457) - But these seem to be an american part number also refered to HGR7DQ on the net

However whats the UK equivolent ???

Or what would people recomend ???

Cheap suppliers are also useful :-)

Thanks,
Lee

Bosch or NGK are the best mate, let me know what prices your getting them for. I might be able to get them cheaper. +++

Actualy having a second look through that thread....Those are for an 3.7 and mines a S8 4.2 AVP.....so they would have posibly been wrong

Hmmm

Has an interesting selection.

Has the NGK for about the same price, probably indicating the above website isn't too bad.

I'm sure I can get you them a lot cheaper, hang on. I'll go and ask my supplier :D

Hi There,

Any joy....I'm probably more tempted with the Bosch ones ?

Ta,

Sorry mate, been trying to look for this thread. I'm afraid he can't get them cheap now. I got 8 NGK Spark plugs, for a A8 and a S6 for £12 about a month ago! I spoke to a few people and they all recommended the NGK over the Boschs, its all NGK do and they are the OEM plug on the B7 RS 4 so it must be a good brand, i'd go with the NGKs over Bosch +++

For my 95 4.2 D2 A8, carsparkplugs.com are recommending:
HGR7KQC
Bosch Super Spark Plug
at £3.62 each and £28.96 for the 8 ex. VAT

and

BUR6EFSZ
NGK Spark Plug
at £3.26 each and £26.11 for the 8 ex. VAT


I see that it is recommending different plugs for the S8 compared to the A8 and different plugs after 1999

For the Bosch:
Total for items: £28.96
Shipping cost: £3.01 (recorded delievery)
VAT at 15%: £4.80
Total amount: £36.77

Are 4.2 A8 plugs the same as 4.2 S8?

can i buy these for my A8?

Hi There,

In messing with engine compression pulled the spark plugs and the ones in there are the NGK R BKR6EQUP - Has the 4 electrodes which reading up seems to be for longevity as only the closest one is used !

Am tempted with some of the iridium ones, BKR6EIX however there seems to be an 11 varient which i can't see why and an LPG....However on some sites these are listed as for Taxis, so i've no idea !!!

cya,
Lee
