2002 XJR Ignition brand preference

Hey there, recently burnt out two coil packs on my 2002 Jaguar XJR after running on a weak battery. Any advice on brands to go with for replacement on “coil packs and spark plugs”. Currently leaning towards a pair of Spectra Premium (part: C727) but not sure yet.

Thanks!

I purchased 2 complete sets from China about 6 years ago, still running on the first set. Where are you located?.

Hello, Really… !? What Brand? I’m located in North Florida USA.

No brand but labelled with the correct part number for my car (‘99 XJR) mine are 2 pin version;
