Folks
Anyone recommend is it worth upgrading from the oem RS4 spark plugs as mine are due to be replaced after 43k on the clock
And if so which ones are recommended

Just a few questions, why not use the recommended NGK SILKGR9A7ES?
Is your car standard or tuned?
Are you having ignition / performance problems?
What increase in 'performance' are you thinking you may gain by changing the plug type?
What does your tuner say you should be running?
Don't forget running a hotter or colder plug can cause ignition problems that can lead to engine damage in some cases.
I'm sure for a standard performance car Audi don't just throw any old spark plug in and pray.
Some tuners even recommend using original factory plugs and coil caps.

Just asking.

car is standard

just throwing the question out there to see if there is any benifits for a upgrade
