The install of the plug wires on my disco wasn't extremely hard. It took about 1/2 hour. I didn't have to pull the intake and it went fairly easy, actually changing them on my old ford explorer was much harder. I say give 'em a try, let us know how they work.

 

How did you tell me how to change the wires on a DII without pulling the intake off? I fouled a wire right after I bought mine, and the dealer wanted $484, parts and labor, to swap the plugs and wires. I told him thanks but no thanks. I did this in the parking lot. I probably took me 1/2 hour just to do one wire. Some of them seemed near impossible to get to without the intake removed.

 

OEM plug wires are cheaper than Magnecor's now.
I have Magnecor's now and have had no problems with them.

 

Since we are on the topic of wires, has anyone tried the STI brand? I replaced the wires with this brand and NGK plugs about 1 month
ago. so far so good, the wires appear to be well made and had good reviews when I looked them up online. Oh, my vehicle is a 2003 Discovery SE7.
