E39 Spark plugs and air filter, any reccomendations?

I'm providing some parts for when my 528 has it's oil service in February. I've heard good things about NGK Irridiums, any thoughts? Thanks.

BMW fit Bosch, try Eurocarparts for the best price, they usually have a choice of two air filters. They supply BMW oil filters too.

Thanks for the tip, just got an air filter (fitted myself as it was a 3 minute job) fuel filter and 6 Bosch spark plugs for £70.

I just did an insp 2 on my dads e39 530i. Genuine BMW plugs I fitted today were stamped up NGK.
