What Spark Plugs ?

[UtilityGuy]

I'm looking to service my MCS R56 next week by starting on the spark plugs, I don't know what's in it right now, All i can assume is its BMW's standard service fitted plugs as its always been into BMW for it's services,

So me being me, I want to cheek them out and have a look at them, Then put some new ones in so I know that they are all ready for 2013's fun n games ahead,

Was thinking of the Bosch Supa 4's and the NGK Iridiums at twice the price of the supa 4's,

So I would like to know what you have and do you have any pro's V con's of the said above 2,

Paul

Hi

if your car is standard stick to standard plugs, there is no advantage and no point in fitting performance plug if you car is standard. i have used NGK all my life in cars and bikes never had a problem. never like bosch my self but thats just me

Sparkplugs UK NGK Champion Denso Sparkplug, Glowplug and Lambda Sensors

best and cheapest i have found with good service
just remember once you have fitted new plugs give it a week or two then check tighten them.
be careful with the coil pack easily damaged.
if it comes down to money remember buy cheep get cheep, do it once do it properly.

The spark plugs fitted supposed to last for 60000 miles before needing a change, unless its a JCW then its 30000 miles.
Not like the old days when they were routinely changed at the 5000 mile service.
