  • Spark plugs are a very important part of your engine's operation. There are many aspects to a spark plug, in this video we cover four of the more basic aspects to a spark plug to help give you a little more knowledge in case you're planning to heavily modify your car. However, I would recommend running the OEM plug for most applications.
    A very special thanks to Advance Auto Parts for sponsoring this video and providing the spark plugs shown.

    I just got a used 2016 Nissan Rogue and wanted to change the spark plugs and went to Nissan to get them cause I didn’t want to take any chances and carefully installed them.

      It is, but it is very expensive compared to copper and only has a slight increase in conductivity

    My owners manual suggest denso and Ngk plugs, 2 from each brand.
    For my 26 yr old car's 1.5L engine, I mistakenly ordered the hotter one. I assumed the lower rating number meant a cooler plug. I was wrong.
    The 2 Densos the manual recommended were a 16 (warmer) and 20 (cooler) rating?

    Do I have to exchange for the cooler? Still waiting for them to arrive

    Hello, I would like to say that I live in a city with a company that produces spark plugs for all cars in the world !! It also produces for Bosch. This company does great quality things called BRISK in the Czech Republic from the city of Tábor.This company also has a world patent for a new of spark plug !!

    Noticeably more power using NGK tr55 in an LS1 vs the stock iridiums. They'll probably work just as well in any car that's naturally aspirated. But since they"re copper they'll need to be changed every few years......maybe. Just use um there great AND CHEAP!

    Worth mentioning: the length of the threaded part is really important too, too long might touch the piston, too short, might not ignite the mixture

    iridium last just a little longer than copper? copper plugs only last 35k to 40k miles if your lucky!!! ive run iridium well over 100k miles and had berrly degraded!!!!!!!

  • Joseph Auler
    Joseph Auler 2 months ago

    Got a FiST and installed the ngk and they were about 2mm shorter than oem and chase a ticking sound when I accelerated. Is that user error in install or does the shorter plug cause this?

    • Revtune
      Revtune 2 months ago

      Probably having a weird form of knock or a delayed flame front (the spread of the fire in the cylinder) since the plug is recessed in the head.

    Don't reuse spark plugs because the crush washer has been crushed and don't put copper grease on the threads of the plug.

  • Richard NZ
    Richard NZ 2 months ago

    you need to know the reach (the most important spec) then the thread pitch also the connector can be screw type screw type with cap or fix cap type ( assholes couldnt make things easier ) and heat range plus the plug height
    you can save alot of money by finding out what spec your original plugs were and looking for other plugs that have the same spec - not just looking for a parts number - some cars had bigger production runs etc

      C Man Try Denso Iridium TT . NGK are one of the best but doesn’t make plugs with such a sharp center electrode as Denso only 0.4 mm diameter for Denso and 0.7 mm for NGK .

    I love quad tipped plugs as you don't have to gap them and they provide the best spark as it always has an electrode to ground to.

    I had a grpund electrode break off on my FIAT 500 engine. After it scored the cylinder and bend an exhaust valve, i just ended up getting a new engine for it. Moral of the story is DO NOT ignore your engine when it starts misfiring

    Spark plugs are pretty dang important, even for just something as regular as changing them for maintenance. Runs smoother and more responsive acceleration.

    Good video. My mate removes the ring washers from the spark plugs when he replaces them. I told him he might regret that but 2 years on his car still fine. He has suzuki swift 1.3 with 167.000 miles. He says it feels better that way ????

    • Flapping Flight
      Flapping Flight 2 months ago

      lee thomas if your spark plugs are Iridium they last about 100 000 miles or 160 000kilometres . You have to drive a lot 80000 km per year in order to need replacement of such a spark plugs after only 2 years .

    • lee thomas
      lee thomas 2 months ago

      @Flapping Flight he told me about TTI. He said they last up to 2 years so i will get them next.

    • Flapping Flight
      Flapping Flight 2 months ago

      lee thomas that is right , I have the same experience with Denso iridium TT but mine additionally are indexed and spark gaps slightly increased by 0.2mm . Most of the guys didn’t believe that such a improvement can be achieved only by spark plugs tweaking. I didn’t believe either before to try it.

  • XY Zebruh

    All you need are plain copper plugs they have the best conductor over iridium and platinum etc

    • XY Zebruh
      XY Zebruh 3 months ago

      @TRUTH SEEKER lol, to each their own, iridiums are great for durability but hands down performance goes to pure coppers

      XY Zebruh 3 months ago

      @TRUTH SEEKER ya thats why guys who run high horsepower cars run coppers because they change them out every season, iridiums are for soccer moms that dont service a racecar and have no need to change plugs every few k of miles. I run copper NGK's in my mk3 Supra on 28psi of boost, the iridiums never made the car run right

    • TRUTH SEEKER
      TRUTH SEEKER 3 months ago +1

      @XY Zebruh If a standard copper plug had a tiny electrode it would not last very long at all..it is only the properties of Iridium that allow it to spark forever without much wear...a smaller electrode results in less voltage required for a spark

    • XY Zebruh
      XY Zebruh 3 months ago

      @TRUTH SEEKER no the iridium acts as a protective conductor to last 100k miles

    I only use Bosch Premium Platinum spark plugs for my vehicle. They do not make any more power. But they last much longer. I have had my vehicle since 1996 and have only changed the sparkplugs twice on this vehicle. I have a 2001 Ford Ranger that I have maintained since new for the original owner. The original Champion plugs had to be changed every year and a half. Both vehicles have around 400,000 miles on them.

    How about running different range plugs in an inline 6?

    I'm running Autolite46's in my old ford 200cid...
    The two middle cylinders always look great, perfect color...
    The next two away from the middle are a little sooty...
    The two on the ends are really dark.

    I bought an old 1975 Step Van. it runs on propane.. it wasn't running nice so after a while I changed the spark plug wires as they looked crappy and it ran a fair bit better but not great so I changed the spark plugs and it ran so different it was amazing.. it was old Van so it was 'miles' on the dashboard... when I filled the propane tank I made notes of milage and before it was 60 miles used 60 litres of propane.. that about 4-1/2 miles per gallon (imperial gallon size) now after I changed the spark plugs it's about 90 miles for 60 litres of propane.. it sounds better, runs faster and more powerful going up hills and stuff and it's about 50% more miles per litre..

    About that "sparkplugs wont broke your engine" a too hot sparkplug can make holes in the piston among other issues.

  • Scott Gaines

    If you dyno test all your mods, try NGK Ruthenium HX (PSPE if boosted) Copper/Nickel plugs will give you the most HP/dollar and Ruthenium will outperform Iridium and platinum. I would like to see some dyno comparisons.

    • Flapping Flight
      Flapping Flight 2 months ago

      Scott Gaines the key word is ruthenium ALLOY :) NGK fall a bit behind Denso with their iridium TT ( BTW its electrodes are Iridium - ruthenium alloy as well) so IMO the name ‘ ruthenium ‘ is most like marketing trick but is possible the content of ruthenium and iridium to be different
      between both manufacturers.BTW Denso iridium TT central electrode diameter is only 0.4 mm when NGK iridium is 0.7 mm and ‘ruthenium ‘ ones are with 0.6 mm . The thinner diameter of the center electrode is directly related to the lower break down voltage of the spark gap.
      What I like with NGK ruthenium is the ground electrode design, it remind me on so called halve gapping on regular plugs ( when ground electrode end , ends exactly over the center of the center electrode ) this is proven to accelerate combustion process by better exposure of air- fuel mixture to the spark and practiced for many years in auto sports .
      I personally have tried Denso iridium TT and would recommend them to everyone over the regular and platinum plugs but haven’t tried yet NGK ruthenium ones so unfortunately I don’t have any direct impressions:(

    Thanks for the video. I was hoping to learn more about decoding the plugs, but still great info. my tuner just noticed I was running plugs that were in the 5 heat range, on a 10.5:1 compression engine running 10-18.5psi on pump gas. And told me to switch to 7s, which should alleviate any pinging I was hearing under boost on conservative timing. (Video of the last pull on my profile)

    A better alternative would be just buying a spark plug like the Torque Master S series. No gapping or indexing required. You can buy a set at www.extremespark.com
