Hi i want to make sure that i can have my mustang last a whileand am interested in these new spark plugs along with MSD Super conductor 8.5mm spark plug wires and a MSD performance coil pack. i have a 02 mustang V6 with 130k miles and keep it maintained. what areas will i show increase of performanceand will there be any down sides? just wondering thank you for you time

Hi, purchased this spark plugs for 99 cobra. They don't seem to be the same size as the ones I just took out. And the coil don't seem to attach properly either.

  • Hello! Please give us a call at 1-844-494-7745 and we can troubleshoot your fitment issue with the NGK G-Power Platinum Performance Spark Plugs


Does it come with the Anti-seize lubricant or spark plug boot, bulb and electrical connector ?


Helpful (0)
  • The NGK G-Power Platinum Performance Spark Plugs (93-01 Cobra; 96-04 GT, Mach1; 98-04 V6) only comes with 8 Spark Plugs. It does not come with the anti-seize lubricant, spark plug boots, or electrical connectors.


I'm new to dealing with spark plugs and am wondering if these would be good for a stock 3.8L V6? i plan on putting in a cold air intake, dual exhaust and long tube headers. Should I get platinum or just stick with Motor Craft copper?or maybe even iridium?


Helpful (0)
  • These would be a great upgrade for your 3.8L V6 Mustang. The NGK Spark plugs are a nice step up from factory that will not hinder performance on a mostly stock car. A platinum spark plug will last a lot longer than a copper one, which means a cleaner burn that is more efficient.


How often should i change out these spark plugs on my 94 Cobra?


Helpful (0)
  • Hi, These NGK G-Power Platinum Performance Spark Plugs should be changed every 30,000 miles when naturally aspirated, If your Mustang has a supercharger or turbo they should be changed yearly.

compatible with nitrous are these plugs good for a nitrous installed 02 gt?

    Installed these plugs with MSD coils and WOW, what a difference. My vehicle had 107,000 miles, but the plugs had been changed sometime prior. With this work thee car is super smooth at idle and responds much better on acceleration. These really woke up the animal in my engine! Highly recommend this combo!

    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.

    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!

    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

    NGK Spark Plugs

    Bought these plugs for a minor tune-up, had a pro install them, I'm not the smartest guy when it comes to maintenance. I noticed my car runs so much smoother now. Didn't notice much of an improvement in my MPG, but I drive a V6 so it's no big deal anyways. Overall, great plugs.

    NGK G Power

    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!

    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

    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.
