spark plugs

Post by juice » Thu Oct 01, 2009 6:42 pm

Hi guys, been doing some research using the search button, but just want to clarify a few things

I know the spark plug used in an RS4 is NGK PFR7Q

however there is also NGK BKR7EIX which is apparently the same plug

http://www.sparkplugs.co.uk/pages/prici ... rs-ccp.asp

if you view the link how comes the PFR's are more expensive? (even with them being platinum/iridium) - the BKR's are iridium but cheaper

i thought it was the other way around, if someone can clarify for me would be great as i need to order these tommorow asap

update - have been advised to use the bosch F5DPOR plugs as they are tried and tested to be the best out there when running higher power

Then why are the OEM plugs for the RS6 NGK's? Despite everything else being Bosch. Audi chose NGK over Bosch which is pretty rare for Audi. They like to keep it German. When's the last time you saw Magnetti Marelli on an Audi? ;)
