Review on 🔌 ENA Set of 8 Ignition Coil Pack: Compatible with Ford Lincoln Jaguar - Thunderbird LS S-Type, 2000-2006, 3.9L 4.0L 4.2L V8. Replacement for DG515 DG509. by Eric Young

Perfect for my 2004 Ford Tbunderbird 3.9L engine. CS seems to be of good quality. The problem of misfires and hesitation has been solved. It remains to be seen if these items will stand the test of time. I will update the review if there is none. The product description says they have a lifetime guarantee, so we'll see. Just a tip - get the 7mm mini flex head ratchet wrench I bought which will help a little with removing and reinstalling the plastic covers. Space under the hood is ridiculously tight, and without a miniature wrench it's nearly impossible to get to the driver's side bolts.
