    What is the difference between these and the Ford SP-505 spark plugs? Are SP-493s or SP-505s recommended for GTs and which has a lesser probability of being shot out by the engine and causing heads to need replaced?

    Marshall

    • For the Ford Motorcraft OEM Spark Plugs, the SP-493 is an OEM plug from the 99-04 GT. the SP-505 is of the same design, but is 1 heat range lower. Neither would have any reduction in the spark plugs being shot from their hole, as this is caused by a failure in the head's soft aluminum threads, which are not as strong as the steel threads on the spark plugs. On many performance applications, steel inserts are installed in the head to replace the aluminum threads to prevent this, though this requires significant modifications to the heads.

    should I get these ford motorcraft oem plugs or NGK G-Power Platinum Performance spark plugs

    lo

    • I would absolutely recommend Motorcraft and be sure to install them properly. Blowing out spark plugs due to improper installation or some aftermarket plugs is very common in these engines.

      Can't ever go wrong with OEM sparkplugs. Perfectly gapped, fit and finish is beautiful, and made my Stang idle smoother for sure. Power feels great up to redline. Will only use these plugs for the rest of the cars life.

      Installed these plugs with Accel Coil Packs and it fixed my horrible misfire. They come pre-gapped but check the gap on them anyways to make sure. Thanks American Muscle!

      Nothing beats oem.

      These plugs are perfect for anyone who drives their mustang daily and has no reason to use aftermarket plugs. My car is only mildly modified and has 183k on the clock. This thing has never idled so smooth on an initial start up in years. Way better than the autolite plugs that the previous owner had in there.

      Great price

      Sorry I have no picture to provide. My car has been hesitating when pushing the gas peddle so I changed the spark plugs along with purchasing new coils as well. After installation my car is no longer hesitating. I wasn't trying to brake the bank so I purchased these bad boys.

      Can go wrong with Motorcraft!

      Had a misfire at low rpm under load in overdrive on my 01 Gt. Put a new set of S R coils on and still had the misfire put the new plugs in and misfire went away! Car only has 78,000 miles in it and previous owner said the plugs were changed which probably wasn't true. Old plugs looked good to the eye but obviously we're weak. The car completely woke up and runs smooth as silk! If there's any question grab these they are cheap insurance and easy to change.

      Motorcraft OEM spark

      Had a misfire cylinder 1 and then another in cylinder 2. Grabbed theses plugs as apart of a 160k mile tune up (coils, alternator, battery) and havent had any issue since. Not a difficult task to install and with the right garage/tools/support likely a hout or less to complete but it was worth taking the time for me to not make any errors with removing the plugs... And the coils have to come out so why not do new there too. (About 2 hours for a casual approach.)

      glad i changed plugs

      I've had the car for a couple of months and had intended to change plugs, glad I did because what was in there were pretty done. I had a pretty good foul in the existing. The only thing I can say remotely bad was that the pre-gaps were a little off but not a big deal. Took a while on the change out because I changed coils at the same time and did without removing fuel rails.
