2.5i M54B25 engine - spark plugs - recommendation

[zriha]

Hi gents,

I was searching this forum and web, and couldn't find straight forward recommendations for spark plugs.

So in plain simple, if you have 2.5i Z4, what spark plugs do you use, and how happy are you with them?

Cheers!

I bought Bosch plugs for mine through Euros, ended up being about £11.00 each, very happy, runs smooth as anything, no pinking and fuel economy is good, obviously running these engines on the Vpower is better for everything to do with the fuelling and ignition on any engine

I wouldn't bother with the iridium's (long life) plugs, i don't really see the point, out of personal preference I'd rather service mine every 7k miles and change every time. Hope this helps.

Cheers

NGK Laser Iridium ILZFR6D11 (1208) . Fitted these to my 2.5si in May 2019 when the engine started misfiring slightly. I went for them following recommendations on this forum and have been very happy with them. Good luck.
