  1. By the way if you shop at Advance Auto and use the code "ChrisFix25" at checkout, you will get 25% off your entire order (order anything, not just plugs). *I do not make a penny from this. I asked Advance Auto for a discount for my Subscribers (and I use it too lol). I hope that helps!

  2. I am a 20 year old college student who know little about cars. Thank you Chris I was able to save a lot of money changing my spark plugs myself rather than having the dealer do it and charge me a fortune!

  3. What if I’m replacing the distributor cap as well? What’s a tip to not get the wires mixed up? I understand why you’re replacing one wire and one plug at a time, but I have to take off all of the wires at the same time to take off the distributor cap

  4. My 1984 LTD Crown Victoria had 216000 km and it still had the original plugs from the factory😅 once I replaced them and the ignition coil the engine ran like it was brand new🤣😭

  5. Well done bro😮
    Your videos have no expiration date.
    Posted in 6y ago and im using it right now.
    hope you enjoy all your moments as i do while watching your videos❤🎉

  6. Chris, on my 4 cylinder mazda3 2016, it has coil packs + spark plug, it doesn't have wires like yours, would I sill use compressed air to remove debris before removing the sparkplugs? The coilpacks are on the top on the engine btw. Thanks!

  7. One good tip is using a silver sharpie to mark which cylinder each coil is from. I also mark each plug with its corresponding cylinder. Trust me its a good practice not only for diagnosis but also to stay on track of which you already did. Look up the firing diagram and write the number on the porcelain and boom u cant mess up.

  8. What if the spark plug is stripped ? Very hard to run , also the spark plug doesn’t have any grip. Any help ??? No one wants to deal with it

  9. All good information. But what if your car is still running great, but the plugs haven't been changed forever?
    My sportage has 315,000 miles on it,still runs good, but I've only changed my plugs one time.
    Should I change them or not?

  10. I did this with my friend, both 14, on a Foxbody Stang. The spark plugs didn't line up at all but it worked! Thanks chrisfix 😂
