We just pulled all the coil wires on my XKR and replaced the 4-wire leads with those from a Corolla. As is the case with many of us, your wiring, if it's not replaced, is likely losing efficacy due to the insulation flaking off like candy coating (because it is. It's literally biodegrading due to EU mandates).

I did a little research and found a set on Rock Auto for about $14 a piece on manufacturer's closeout. Crossmatching the part number, these "FAMOUS BRAND" coils actually turned out to be the Carquest Premium Ignition Coils (carried by Advance Auto Parts). Doing even more digging, I found these to be made by Wells, which is a decent OEM replacement supplier. The price on the Advance Auto site for the same exact EBC1805 coils is $116.99 a piece (!).

They came in and look really good, right on par with the Denso. They work great so far. https://www.rockauto.com/en/parts/fa...tion+coil,7060

 

Great find, tried ordering a set but they wont post to the uk. Damm

 

I did the same thing with RockAuto. “Famous Brand” part number correlated to NGK. When came Delphi. They only had one bolt hole. Told RockAuto. They refunded and said keep them.

 

I am inclined to describe budget parts as a “very good deal” after they have endured the test of time and mileage for a decade, or at least a few thousand miles and a driving season.

and not immediately after a successful installation and initial drive.

They did pass the initial sniff test and, having seen some really garbage coils, was pretty surprised. But yes, if I still have this car in 10 years and the coils are still going strong, I'll be more inclined to give an endorsement as a good value. But by then, Rock Auto will be only available by the Musk-brand cranial wifi and our cars will be outlawed on three planets.

 

which three ?

 

A friend in the UK buys from Rock Auto regularly and gets very fast delivery. I'll ask if he does anything 'clever'.

 

Just asked him and he says he just orders like all his mates with US trucks in the UK. So, you should be able to order them and confirmed an amazing delivery time.
