DelphiGN10448 Pencil Coil

Work well. Actual brand and model# as stock jaguar 4.2 SC but at 40% of the cost from Jaguar.

Got this to replace a broken coil pack on my 2005 Land Rover LR3 SE with a 4.4L V8. It was a perfect fit and was a perfect OEM replacement. My LR3 is on the road again.

Replaced all 8 spark plugs and coils at 230,000 miles on 2006 LR3. Started having issues randomly with cold start rough idle. Was getting P0301 P0308 and P0300 on occasion. Very intermittent on check engine light manifest but more frequent driveability issues. I'm a life long Senior level Technician specializing in advanced diagnostics with network systems. I was able to identify through sensor PID data that timing sensors were erroneous. After being fed up with fighting the random issues I used an ossciliscope on a variety of sensors from ckp CMP and vct thinking I had a timing component failing. Then I determined that the coils potentially were back feeding voltage through the circuits into the PCM causing issues with multiple sensor outputs and inputs. Swapped coils out with genuine LR coils and engine has not manifested the rough cold start ilde since. My consensus is that these "name brand" Delphi coils are Junk... Unfortunately this is a poor product for the LR3 series and the RRS. Buyer beware.

I had a Cylinder 6 misfire on my LR3. This was a direct replacement and fixed the problem.I'll buy another 7 when I can afford it.

This is a great replacement for the Jaguar part! Excellent product at a very good price will use these people again.

It replaces another coil that lasted less than 20,000 mi (not the same brand).

Fix misfiring problem on my 2006Jag XJ8.Working good so far, will see for how long.

These Coil are of Lowest. AFTER MARKET quality, I have bought at this point probably 20 of them to put into my Jaguar X350.I have been chasing misfires for years now.It finally dawned on me, its not my car it is these spark plugs coils. It angers me that Delphi would pump out this Crap.
