        Will these plugs work well with my 06 gt stock everything?

        • Hello! This set of eight (8) Autolite HT0 Spark Plugs are specifically designed as an upgrade for nitrous or force inducted 2005 to 2008 GT Mustangs. These plugs are factory gaped at 0.045 inch. They would not be a good option or necessarily even work on a stock GT.

        i see that these plugs are good for nos. but i daily drive my mustang and drag it every now and then so i would like to know if these plugs are good for when i daily my mustang and do not use my nos!

        • Hi, These plugs are 1 degree colder than your stock plugs and can still be used for your daily driver and on the track.

        Are these 2 piece like OEM for the 3V head or are they one piece plugs?

        • The Autolite HT0 Spark Plug (05-08 GT) are one piece spark plugs.

        Helpful (0)

        Use without NOS or an S/C? I have a few upgrades but I'm not running NOS or a S/C and I would like to put some better plugs in other then the 2 piece OEM plugs will these work fine in my stang or give me more headache then performance? Thanks for the help.

        • The Autolite HT0 Spark Plug (05-08 GT) would do more harm than good if you didn't have the proper power (i.e. a boosted application of some sort) in order to support it.

        Helpful (0)

        Can i use these spark plugs even though i cant get supercharge yet? Im due for some new sparkplugs, 82,xxx miles. What plugs do u recommend?

        • These plugs are a different heat range than the stock plugs and for a naturally aspirated engine (no boost), you should get the Autolite HT1s.

          Great plugs, the original HT0 had 50,000 miles on them, still good but decided to change them since I was working on the car. Forced induction (supercharger), gapped the plugs at .030.... Soaked down the old plugs with Nut Buster for 24 hours prior to removing and none broke off...

          Worked great, eliminated detonation!

          Replaced factory plugs with these, had minor detonation even w/93 octane ... all stock. Replaced plugs, runs great, cut detonation down to almost nothing. Perfect! PB Blast the old plugs for a few hours, the get a good fitting 9/16 socket on cold motor, by hand, go slow ... no broken plugs.

          Great

          Went to local store for same plugs, about 3-4$ more per plug as well as being out of state. Got these guys great price and a day early. Easy install as well. So far they are performing great with the turbo.

          They Work Well

          These plugs were affordable. working well in my 06 mustang GT that I added a Roushcharger. its been a year and 10k miles with no misfires nor issues. You do not gain any power from a sparkplug change and never change your plugs before 100k miles. factory plugs are platinum.

          great plugs

          These plugs worked well for me on my 06 mustang. I've read they are much better on a forced induction application so I will be trying a hotter plug next time around. Still worked great over my 100k mile stock plugs.

          appear to be great plugs, can notice a slight improvement in performance. they are supposed to be 1 piece body so they wont separate like originals.
