Spark plugs

Hi guys,

What is the best spark plugs for my 2004 e46 318i (2.0L[/align] engine)?

Have u check the owners manual? I would suggest whatever it states in there. There's and article in Jan 2015 car mag about using plugs not recommended by the manufacturer. Although going a step above the minimum requirement isn't a bad idea.


Further more I have no input

Thanks I will check the manual, just thought maybe an upgrade was possible

My book says NGK. So I use those. ..never had a prob.

Stick to copper, don't go the iridium or platinum route?

As far as I know bmw doesn't use what they call 'waste spark ignition', as each cylinder has its own coil pack. Apparently copper core plugs don't last with regards to the former

The guys at Midas and Autozone both found on their system that NGK Platinum Laser are the manufacturer spec for my car. This vs Iridium plugs?

No idea......what does the book say? Usually the systems are trustworthy

In your bmw owners manual. Should be close to the back. A quick Google search brought up this. http://www.bimmerforums.co.uk/forum/f18/2002-e46-318i-n42-spark-plug-choice-t94572/

So I used Liqui Moli engine flush before the oil service, and put in Liqui Moli injector cleaner before I change plugs. I got myself a set of platinum-iridium Bosch plugs. Thanks for the help guys. Ps also fitted a K&N air filter. :rollsmile:
