quick starts
these plugs definitely make my 97 triumph thunderbird easier to start and seem to put a little more pull in the mid range . I had ngk plugs in the bike and don't think they had any more than 10,000 miles on them so im pretty sure it wasn't that the old ones were bad. All in all i,m very pleased with this productVerified purchase: YesCondition: New

Best bang for buck
I have used a lot of plugs in my time n these are best for value I have used... We have tried them in Honda trx300, 250es n 200e... More power, faster starting, smoother throttle n idol... Best replacement for outdated NGK DR8ES plugsVerified purchase: YesCondition: Pre-owned
