  • The best spark plugs are the ones recommended by your manufacturer. It could be Denso, NGK, Champion, Bosch or Autolite. Choose the right plug for your car - the one listed in your owner's manual.

  • Ya, I've seen some great plugs from Denso. they're considered a stock plug for Toyota. I guess the "best" plug for an engine depends on what type of ignition system is being utilized. Other characteristics to consider are plug electrode materials, electrode design, thread diameter, reach, heat range and electrical resistance.

  • Some Bosch are pregapped for .43 which my 08 Cobalt calls for. Should I still check the gap or just put them in trusting the pregap?

  • @MarcIzKool If you think American cars are the only types of cars that have engine covers, then you obviously don't know shit about cars! And you also think that American car engines are complicated?

    Here's some advice for you, don't ever try to work on your own cars engine, and leave it to the experts. Better yet, not having a car is the best choice for you. That way, if it was something you had, it won't end up on the used car market as a lemon! Go back to your little B-ball video clips kid!

  • Why do American car makers make the engine so complicated. Why all the covers!!! No need for that, other than covering up the horrible engine underneath

  • Where the heck is the distributor cap???

  • As for the part numbers for the plugs…

    X=2.0L(.035 gap) 41-108

    F=2.2L(.040 gap) 41-103

    B=2.4L (.040 gap) 41-103

    The boots if yours are brittle or cracked are 50056-1 (replaced the 50056)

  • Wow! Rarely do you find a professional mechanic who is this gentile with a vehicle. Some great tips in this video, even if you don’t have a cobalt. Tip, to find out which engine you have, look at the owners manual under ‘service (section 5’vechicle identification) page 5-113 & 5-122 for the 2008 model. If you don’t have the manual, the eighth (8) digit of the VIN is the engine code. X=2.0L(.035 gap), F=2.2L(.040 gap), or B=2.4L (.040 gap)

  • same engine founed on the cavalier and thesaturn ion, i recommend ngk and denso,i think denso are the best......

  • why no anti seize on the plugs?
