spark plug type
 

I have a 1984 Audi 4000s/80 fuel injected 1.8 automatic which are the best plug I can use for it. I put in the ones that were like what it had from new from Bosch but the did not last very long like NGKs but don't know witch I should get.

I would see if NGK make iridium plugs for your car.Have been running Iridium for a good few years now and they are superb plugs. Actually since 1986 ish have been using NGK if available and have nothing but praise for them.

thanks man I know denzo has that type but don't know a lot about that brand

NGK are huge players in the spark plug world.Way back in the 80's i think they were marketed for high performance cars possessing top notch design and performance.You have got to try them out!

:tup:

I have been using NGK for a long time just was not shere on the type to use in it thanks man.
