You'll be fine, just gap them up to the OEM specks as these will come in tighter.

What is the OEM spec?

[Chilled]

I can't find the spec sheet, but FCP Euro has the correct spec on the OEM P/N. Look up the P/N you need for the OEM plugs, it will have the gap size.

Gap the NGK's to the OE size.

I need to buy the thin walled socket.

Do I need swivel if I already have swivel drive adapters?
