What kind of spark plugs should I get for my 2000 4.0l? Doing some maintenance and some touch ups to it today and figured these needs to be replaced as well.

 

This depends on who you ask...I went with the Bosch Plat 4's, haven'thad any problems seems to run perfect.

 

disco mike says +4s

I use them and they work great... but can't compare them to anything as I was previously running plugs that were probably 100k miles old

 

my vote is for NGK iridiums

 

I've had awesome success with these E3 spark plugs. Can't say enough good things about them.

Suede,

How long have you been using the E3s and what wires are you using?

Thanks!

 

Champion Platinum's it is then, installed.

 

I've got 22,000 miles on them so far, with Vitek wires. The wires are a bit overkill, as I know from prior use on my Volvo - Magnecor's are a great wire, and about $50 cheaper. But I was upgrading to a MSD ignition, and wanted every bit of electro magnetic insulation I could muster. For those trying to squeeze every last mpg out of their Disco, I highly reccommend considering adding a basic multi-spark ignition module. My disco purrs on the MSD/Vitek/E3 setup...

 

I too am running the E3 spark plug, both in my Rover and the wifes Volvo.
And Kingsbourne plug wires in both as well.

Who said Champion Platinums? I ran them with Bosch wires and they didn't last for anything. Fouled out in 3 months.

Magnacor wires and Bosch +4 Plugs...
