Per thread title,

Any thoughts on which plugs/oil and cheapest place to buy currently please?

I have sorted filters already as I was ordering some B4’s and top mounts, so added them onto that order... but wasn’t sure which way to go with plugs & oil.

I think OEM plugs are NGK on the N52, at least that was the spec for mine (06).

Do your coilpacks too (Bosch), Autodoc have them cheap usually and check part no if poss which was 221 504 467 but is now 221 504 470. Be careful when you shop for coilpacks you might get ones where the connector has a lug off-centre instead of central which happened to me so best to check manufacturer part no instead of relying on website.
 
The N52 either came with NGK LZFR6AP11GS or Bosch FR7NPP332 depending on the model year, but Iridium is a far superior material.
 
Thanks gents, the Filters I’ve already ordered are Mann, I’ll have a look at the Denso iridium Plugs :thumbsup:
