1993 100 Quattro Spark Plug
 

I have a '93 100 CS Quattro. I want to change the spark plugs. The owner's manual calls out BKUR6ET-10, which is NGK 3 prong. Its about $4.50 each. There is no Bosch single platinum listed for this car. The Bosch+2 is $4 each and +4 is $6 each. I called up Audi delaership and their price is $12 each. What do people recommend? NGK, Bosch+2, Bosch+4, Audi, or something else? Thanks.

I use the Bosch platinum +4 on 91 100q and I can't say that they are any worse than the OEM.

I use platinum +4 also, I go with the idea "2 heads better that one". If 1 of 4 ignite its the same that 1 of 1 ignites, but with better percetage of success.
if 4 of 4 ignite its the same as 1 of 1 ignite but with better coverage.
well thats confusing.
