    Are these spark plugs a one piece designed that will NOT break in two pieces when removing ?

    AndresR

    Would you say these are a hot or cold plug, on the standard 4.6 engine a hot plug would be used and on a twin turbo or supercharged engine I believe a colder plug would be used, is this correct? Or will this plug do both ranges? Regards Pete.

    PeteB

    Are these MOTORCRAFT spark plugs the SP514 updated design PZH1F? This new design from Ford is supposedly stronger with less chance of breakage.

    Buchjr1

    • The Ford Motorcraft OEM Spark Plugs are going to be the SP-514 model.

    What is the torq lb on the spark plugs for a 2005 mustang gt 4.0L engine

    TimothyN

    • You will want to torque these Ford Motorcraft OEM Spark Plugs and other plugs to 33ft-lbs on 4.6L GT's. These plugs will not work with a 4.0L V6, however the torque specs or 4.0L's are 25ft-lbs.

      A Lot More Pep

      Even though car only has 25K, I thought that after thirteen years I should change out the plugs, since I was also installing ACCEL Super Coil On Plug Kit. I took advice of reviewers and went with the Ford OEM plugs. Seems to have been a good choice. So far, no issues and the car runs great! Certainly a lot more "pep" than before. I was also elated to find that the original plugs had virtually no carbon build-up. All the mods to my engine are the "bolt-ons" (CAI, 62mm throttle body, headers and exhaust, under-pulley kit, 'Bama 93 tunes) plus lotsa suspension work. Car is running better now than it ever has!

      Fixed My Hesitation

      Prior to having these plugs installed my mustang would hesitate/surge from 4.5-5.5k rpm under heavy acceleration. I did an oil and filter change and put these spark plugs in and my mustang now runs perfectly, No more hesitation just a whole lot of smiles.

      Perfect

      Matched these with some MSD blaster coil packs , soaked the plug in PB blaster for about an hour an a half and kept reapplying it. All 8 plugs came out jus fine no breaks new plugs and packs went in smooth. This fixed my rough idle and I think it helped with RPM hang as well. Doesn’t happen half as much as it used to

      Mustang GT OEM Spark Plugs

      I decided to replace the plugs in my 2006 Mustang GT. This was first replacement. The car has 82,000 miles. Getting the old plugs out is tricky and takes a lot of patience to avoid breaking off the tip in the engine. I decided to go with OEM plugs after reading up on the subject. American Muscle parts provided good value. Definitely noticed increased performance with the new plugs and coils.

      spark plug

      plug works good, i bought car used at 130000, previous owner never changed them, imagine what the old plugs looked like, broke 3 getting them out. i think plug design is not all good, antisieze, and i will be backing them out every 10000 to make sure this won't happen again.
