Default Which Spark Plug?

Hello all,

Looking to change the plugs in my 2005 GT. Not sure which plug to get. I'd like to put one piece plugs in it, however the choices are limited.

MSD had one but it looks like it has been discontinued.

Any recommendations?

Thanks for your time!

I found a deal on both Champion and Brisks. I can get the Brisks for approx $20.00 more than the Champions. I assume the Brisks will only last around 20k though.

you can try the Champions, I hope they work for you. I tried E3 and Autolite HT1 plugs in my 05' GT and got multiple misfire codes then it went to limp mode. went with the oem Motorcraft SP-514 plugs with nickel anti-seize on the snouts only, keep it off the ground stirrup. good luck

Thanks. I've had bad luck with Champions in the past and I'm hesitant to buy them.

I'm on my second set of champions. first set was installed at 10K. Replaced at 80K with a new set, have 5K on this second set.

No issues with either set. Ford's revised two-piece design is still two piece. The Anti sieze is a band-aid fix IMO.

If you don't like champion, use brisk but I don't think they make an OEM heat range, only cooler which will lead to carbon build up on a non FI motor.

With the Champions, I think people forget that because it is a more traditional style plug, you have to check the gap on them. If you don't check the gap, that can cause misfires, etc.

I'm also on my second set of Champions with no issues. I also sleep better. Whatever you go with use some of the nickel anti seize, just keep it off the firing end.

I also went with the OEM plugs on my 05 with the anti-seize. I would recommend you have the Lisle tool lined up if this is your daily and you need it right away.
