Spark Plugs for my 1989 80 2.0 8v 3A Sport?

[Donald_MacIver]

Right, i am needing some info on what plugs should actualy be fitted to my car. I suspect it currently has the wrong ones fitted?

The plugs i have at the moment are Bosch W7 DTC, but i don't think these are the right ones? I have previously swapped the plugs, leads, distributor cap etc round between my blue 80 and the pink 1991 80 2.0 8v i have as a doner to try and eliminate a running problem i had, but now i am not sure which plugs are the correct ones? The plugs that are in the pink 80 at the moment are Bosch W7 LTCR?

What's making it even more confusing is that i don't think it's the same engine in both cars, my 1990 G plate 80 sport definately has the 3A engine, but the donor car is a 1991 J plate 2.0 8v Sport Edition, and to look at there are a number of differences between the 2.

Any help to sort out my confurion would be very much appreciated.

PS, looking to renew the HT leads, Distrib Cap and Rotor Arm too, so if anyone has any part no's for those that i could cross refernce that would be of much assistance

According to this site, neither of the 2 sets i have had in my car are the right ones, any opinions?

Id go with the BUR6 ET's. They appear in my NGK sparkplug book for audi 80's with the 2.0 litre 8valve engine, unfortunately it dosent specifically include the engine code youve given.

Haynes says Bosch WR 7 LT+ with a 0.8 mm gap.

Not related to this engine, but the KV engine for the Cq is not listed correctly by Audi it only goes as far as 1985, you have to look at the 90Q to get the correct spark plug which is W6DTC's......
