    Hey, guys, Adam here with Today I'm bringing you a quick overview of the NGK G-Power Platinum Performance Spark Plugs, which are available for all '93 to '01 Cobras, '96 to '04 GTs and Mach 1 models, as well as the '98 to '04 V6s. The NGK G-Power Platinum Performance Spark Plugs you see here today will be for any '93 to '04 Mustang owner who might be looking to swap out their factory plugs that may be old, worn out, and misfiring for a set of upgraded performance options from NGK. This will give you an overall quicker start, lower emissions, improved fuel economy, and also reduces the required voltage. This is gonna be for the guys with stock or mildly modified Mustangs, of course, since it does have a heat range of a normal five.Obviously, spark plugs are crucial in keeping your lightly modified or stock push router mod motor running smoothly and efficiently. Now, obviously, NGK has been making spark plugs for years and these are gonna be a performance upgrade with a better material. Now, if you're looking at a bad set of spark plugs in your motor, you could experience a number of symptoms, symptoms such as a rough idle, a rough start even, bad fuel mileage, things of that nature, the list goes on and on. This is definitely a good upgrade to improve of everything I just mentioned, giving you a better fuel efficiency, better throttle response even with a smoother and quicker start. When you're shopping around for plugs you want to make sure you're taking note of what the heat range is because that will determine which plugs to go with your particular setup. For example, NGK's heat range goes from a 2 to an 11, but you want to take note because this particular manufacturer actually goes a little bit more backwards in some of the other brands. What I mean by that is typically a heat range number that's higher would mean it's a hotter plug. With NGK, it's actually the complete opposite. The higher the number, the colder the plug. Now, the reason you'd want a colder plug is for a forced induction setup or something of a higher horsepower motor. Now, in this particular case, you're looking at a heat range of five, which is extremely normal, which means, again, just to reiterate, this is for the lightly modified or bone stock motor. As far as materials and construction goes, this was manufactured from NGK with a copper core to give its superior conductivity and a platinum tip for a clean burn that also reduces the amount of voltage required to make the engine run at full power.The G-Power options were also manufactured with a trivalent metal plating to make sure that it also has anti-seizing capabilities as well as anti-corrosion. As far as pricing is concerned, this will come in around the $30 mark, which, believe it or not, is actually less than a Ford OEM replacement you'd get at say Pep Boys. With that said I did use these exact plugs in my '95 Cobra, which was naturally aspirated and slightly built, and they started up fantastically and had a great idle. I never had any complaints. So if that's similar to your setup or if you've got a stock motor I definitely recommend these plugs.Now, obviously, as far as installation goes, changing some spark plugs are extremely straightforward. You want to have a ratchet and socket set on deck and a few extensions of different sizes, as well as a spark plug grabber socket just to make sure you don't drop this down to the engine bay, which can be a huge headache.With that said, you might also want some anti-seizing grease, if you want to use those as well, but the material is geared to prevent some of that. But if you want to make it extra secure, that's up to you. Overall, it shouldn't take you longer than about two hours from start to finish to swap these out. I'll definitely give it a one out of three wrenches on our difficulty meter. Just to wrap this one up here, if you're the owner of a '93 to '04 Mustang, whether it's a GT, Mach 1, or V6, given the respective years, you definitely want to check out the NGK G-Power Platinum Performance Spark Plugs, which you can find right here at

    I ordered these plugs for my '01 Bullitt (4.6L) and I was just wondering if you could tell what the proper gap would be for my engine type. I've seen answers ranging from .32 up to .54 ?

      Ordered Monday, here Wednesday! Put em in today on my GT. Had a slight miss with the stockers, and these fixed it! These spark plugs have a LOT more threads on them, compared to the stock ones. Twice the amount. No noticeable power gains, they're just spark plugs. But there is more consistent power throughout the power band. No missing. Great product, and great service, AM!

      01 GT with 44k Miles

      Just installed these on my stock 01 GT. Car runs much smoother, Didnt noticed boost in performance tho. Make sure you gap em to 0.054 for GTs since these plugs were not gapped when I Unboxed them. Overall I didnt feel any difference in performance, but these are bettern then Motorcraft or Bosch,

      NGK Platinum Spark Plugs

      Installed NGK Platinum Spark Plugs, MSD Superconductor plug wires, and a Screamin' Demon Coil Pack onto my 2004 Mustang V6 in less than a hour. Replaced my stock plugs and wires, as well as my stock coil pack. Resolved my rough idle, and definitely increased my throttle response. All three are recommended to keep your Mustang running at tip-top shape.

      Buy Ford OEM!!!!

      I recently bought these along with new coils and injectors. Got them all in and my car ran terrible. Checked all the gaps and they were dead on. After more inspection I figured out it just won't run right without Ford plugs. May have been a bad batch but you live and learn. Save yourself the headache and buy OEM if you have a N/A car. At least it was what fixed my issue.

      great plugs

      i started to notice that my car didn't have as much pick up or as good as a throttle response recently so i bought some of these plugs. i have a gt hood with the hood scoop taken off so the hole and bolt holes was clearly visible so my engine compartment wasn't exactly protected from Florida's rainy humid environment. i took the old plugs out and they were absolutely just gross....super glad i had these platinum's on deck to swap em in and they did what they were intended to do, woke up my car much better throttle response and smoother acceleration. great product 5 stars absolutely.

      Great plugs, just buy these

      NGK makes an excellent plug. These are a good plug to use to replace your factory plugs in your mustang. Mine came pre-gapped at .055, which is nice. They also shipped with dielectric grease to put in the plug boots. These plugs are a great value for the price, and more than what you will need unless your motor is a long ways from stock. AM shipped quickly as usual, Thanks AM!

      NGK Plugs

      Great plugs- my car actually felt a bit less bogged down in the lower rpms than w/ my old plugs and the car is running a little smoother also.* Be careful to blow all the debris out of the cylinder head with compressed air before you pull out the old plugs because otherwise everything will fall right into the combustion chamber when you pull them out. Also thanks to american muscle for great prices and fast shipping

      Like taking ur car to the doctor

      My car had been running rough for a while. So I decided to buy these O.E equivalent plugs. I bought my car used 2 years ago. Today I changed the plugs and to my surprise whoever put plugs last did the most idiotic thing, they put in Bosch Platinum +4s. My car runs so much smoother now and doesn't feel like it misfires anymore. No mods on my car if you want a super smooth feel without forking so much money then these are the way to go

      Check Your Plugs!

      I had no idea how bad my old plugs were! These are great, especially for the price. I changed out the coil and wires, too, but I would definitely recommend swapping out for these plugs. Either way, at least check the ones you've got, especially if you aren't the car's first owner!
