Is it f8dpp332 or fr7dpp22u
 

Hello,

Spark plugs on my car (2001 e200k) are not original and it has a rough idle. The only numbers I found online was the f8dpp and the fr7dpp, also I found online that spark plugs for my car should not have resistor r . So what is the bosch spark plug number that should I buy??

Thanks.
