    Thankyou for that explanation. I've had a 00 wj for around 10 years and I am never going to sell it. So I'm trying to learn how to do as many things as I can to fix it up.

    Thanks for the information. I have a 2000 Jeep 4.0 and I will install the FR5N.

    You're a little off on how wasted spark actually works. One fires at TDC of the compression stroke while the other fires at TDC of the exhaust stroke of its paired cylinder. 1-6, 2-5 & 3-4 are the paired sparks because those are the cylinders that hit TDC simultaneously.
    It's called wasted spark because you're essentially running the ignition as if it was for a 2-stroke, the one that fires at TDC exhaust is quite literally wasted as it does absolutely nothing, and that is kinda the point.

    I appreciate the info about the wasted spark ignition. Good info. I drive a 2000 xj 4.0. My wife drives a 98 xj 4.0. I can now explain to my wife the difference in price. 😂

    I don’t care what anyone says about iridium’s. If you have a 4.0 with the cop or dis ignition coil then your 4.0 will run fine on iridium. I wouldn’t waste them on a beater though. Been running iridium’s on every new style coil ignition engine with no problems here. The e3 strap is a little to big for motors I’m worried about airflow and hp. But I’ve run auto lite and ngk with no issues at all. Never broke a plug and always carefully gap them.

      I have and continued to install (and recommend) the plug type originally used by the manufacturer.

      @@superb60ce I would if manufacturers truly cared about your car but they don’t. Run the factory service interval on a ford ptu and see what happens. Run the factory oil change interval on a turbo or vvt engine and you’ll regret it. I love iridium’s for the simple fact that if I put a brand new coil and plugs at the same time chances are they will both last the same amount of life.

    Nice video, thanks mate. Question, I have a 2001 4,0 TJ and recently installed new plugs HELLA Iridium Pro, they work fine and I don't notice anything performance wise. But I think they are shorter than the NGK I used before. What do you think about iridium plugs, are they better all around or do they just have a longer life? Greetings from across the pond ;-)

    • @superb60ce
      @superb60ce  2 ปีที่แล้ว +2

      I am not a fan of using ANY plug that the ignition system was not designed for. Platinum and Iridium plugs were designed to last longer, and are installed in ignition systems designed for them. In Jeep 4.0s, I recommend sticking with standard NGK plugs.

      @@superb60ce Thanks for your reply, you must be correct because my recent experience is that the 4.0 actually performs less. I went out today and bought the ZFR5N and will change them out tomorrow. Question about the flame kernel being closer to the piston. Am I correct to say that both plugs are the same in lengt (from the base to the top of the ground electrode?) If so, then the flame kernel of the new plug is actually not closer to the piston, the spark only has to bridge a smaller gap right?

    Hey Super B, can I use the ngk Zfr5n in a jeep 98 4.0 insted of fr5-1? Any improve to the combustion?

    • @superb60ce
      @superb60ce  2 ปีที่แล้ว +1

      Yes you can use them, and it should improve combustion because it is placing the flame kernel closer to the piston
