The OEM plug for the Jaguar XF 3.0L is the NGK 93476 SILZKAR7E8S Laser Iridium Plug.

Can anyone help me find a one or two step colder plug that has a non-protruded tip. I have called around and can;t seem to find anything. I am hoping someone here or in the UK side can help out. I am about to begin install of the SB150i6 kit and need a colder plug but MUST NOT have the protruded tip.

The kit is almost here (presuming it will be shipped in the next few day) and after initial flow testing, I will begin climbing the ladder, but can't go far without addressing the protruded tip on the iridium plugs. I know I will likely not find an iridium plug and that is not a problem.

I can go with a shorter plug life since I will be checking them often anyways.

The NGK SILKAR8AI-9 is the next colder step in the Iridium range, but the tips are longer than DaLeggyBlonde's nipples on a cold day.

This will reduce the metal protrusion in the chamber.
