    I replaced my old NGKs with Champion Spark plugs this past summer. I've had problems with Champion plugs in the past and it was not my first choice to use them, but the store I was at was out of the NGKs size I needed, so I figured I'd try them and see how they work. Do far - so good! I may just replace them for NGKs when I find the correct size and keep the Champions for spares in the tool pouch. >PD<

    That's unheard of (by me anyways) I've always had good luck with NGKs in all of my bikes (too many to remember) I change my plugs about every two years or so (depending on how many miles I ride) On some of my older bikes, I ran with the original NGK plugs for the life of the bike. I ust cleaned and re-gapped them and put'm back in! I guess it's like oil, tires and woman...you stick to the ones you have good luck with!! 8O

    they were bought at the same store about two months apart
    maybe that box fell off the truck or something ?
    if it wasn't for bad luck i wouldn't have any
    what i want to try are those Bosch four prong, no gap, fancy pants plugs

    I'm running the Champs. They don't get very old in my Bike so I pretty much consider them disposable.

    While the Oil is draining-out of the Bike for its 25-Hundred or 3-Thousand Mile Chamge ... I'm gapping-up the New Plugs and sticking them in the Bike and getting a Read off the Old ones as they are changed-out too.

    This worked wonders for me last season because I was tweaking on-the-go and mmanaged to find the (THE) Spot where I was getting Ideal Performance.

    Ideal.

    Purr ... fect idle!
    And, top out-of-the-hole acceleration with adequate engine braking to let me feel the full potential of the Machine.

    Champion NR9YC ... .032 Gapped.
    Wonderful response and performance without big bucks outlaid for Sparklers all Summer long.

    A very possible explanation. I used to keep my plugs in the safest spot possible when I had an auto shop. Dropping a box could be a major expense.

    I'd like to try those too. I read somewhere that the NGK iridium plugs were good for a 2 HP increase on average as tested on a Dyno. The platinum tips I've used in my cages have it all over the old plugs. I won't even tell you how many miles I have on them. I just haven't had a reason to change them.

    There's no need to install an expensive Spark Plug until you have the Tuning as close to or right on the money. There's little to gain if you spend another 12 -to- 15 Dollars for Plugs if the Big Picture is still a little bit out of focus.

    You can "Play" with some 3 Dollar Plugs and do a few Plug Reads until you are confident that all four cylinders are Tuned-in to the correct Mixtures to give you the Bikes Maximun Performance.

    Otherwise, you are just spending more money for Plugs that are ... in some cases ... designed to help keep an Engine NOT tuned to its peak ... running without fouling as easily as a budget-minded Plug would in the same situation.

    Once you have all four Cylinders Dialed-in and running on a Air~Fuel Mixture that delivers Maximum Performance ... then, you can spend the extra cash for the Designer Plugs and the Iridium Sparklers to fire your Engine and deliver a degree more of Performance and expect them to last longer than a "Regular" set of Plugs would.

    Pods, Clean-Tuning, Clunk Tests, Anti-tamper Plugs, Anti-tamper Plugs out and mangled Mixture Screws, lots of Posts about not Idling right or not running right ... Air leaks and whatever else gets in the way of being in a pretty narrow window of fine-tuning.

    It takes a lot of time and patience to bring these bikes in to The Sweet Spot.

    I'm not saying that there aren't some of us who can go to the Auto Parts Store and order a set of the Best Iridium Racing Plugs NGK makes.

    But, you have to admit ... there are probably more Members who aren't quite there as yet.

    But, I know they are working on it. Or, they wouldn't be with us trying so hard to get there!

    Fancy 4 prong plugs are worthless. When I was into the street car scene, we dyno tested just about every plug out there and there were ZERO gains as far as horsepower is concerned... NONE! We tried iridium to copper, bosch to Autolite... No improvement what so ever. Put a plug you trust in there and run it. No point in spending 8 bucks a plug!

    The fancy 4 prong plugs are a waste of money in my opinion. (read the reviews) I was just wondering what brands everyone was using. Basically just wanted to know if the Champions had any good reviews. I guess I assumed NGKs were the most popular being they were standard equipment on these bikes.
    I'm sure being the Champions were brand new, they would run good right off the get go, but I was just wondering how long they have lasted for members who used them for any length of time.
    I know the ones in my Honda Accord had 100,000 miles on them when I replaced them and they were NGKs, It still ran good when I replaced them but I figured it was about time for new ones.

    I dont know if Autolite makes a plug for our bikes but I have been using them for a loooong time after a bad run with Bosch.. I'll never use the Bosch brand plugs again.

    NGK are Standard because they cut a deal with the Manufacturers and they are Made in Japan.

    Once you need Plugs you are free to select whatever brand you want to run with.

    I use Champion because I grew-up using Champion in everything. I used to be a Quaker State Oil Guy too. But have since switched to Castrol GTX.

    Now, with a Monte Carlo to Oil ... I have to find a reasonable price on Mobil-1.

    I use the factory recommended NGK (D8EA I believe) and they treat me well. Was going to invest in the irridium plugs, but after some research decided they wouldn't make a noticeable difference, ie: they wont produce a hotter spark, they just last longer (which is not a concern for me).
    I'm a firm believer in what Rick stated above. That the best performance to be obtained in our bikes is to have them as perfectly tuned as possible.

    I just bought a set of the NGK iridium plugs. I am trying to just get enough fire so that it stays lit on my near freezing mornings. It's going to be awhile before I get it dialed in, but started would be nice. And regularly starting would be even better.
