Just wonder what everyone thinks about replacing spark plugs. Which brand is the best for an 01 F4i? NGK iridium plugs what about them. As for replacing them what is the easiest way to replace them??? websites or helpful links are welcome

 

Unless you're having problems with you current type I'd suggest going back with the same type and heat range. NGK are excellent. As far as how to do it -- only way I know of is to pull the tank and change 'em 1 at a time. If you have a compressor blow out all the crap BEFORE you remove the plugs.
