    Have been skeptical of sellers in the past and I reached out to ask all kinds of questions and this seller was happy to respond and help me feel comfortable about my purchase. I then ordered the item and it was shipped and at my door in only a few days. Item was exactly as described and I am so very excited to install it. Would recommend this seller again and again!

    I tried to cancel the order after purchase but the system wouldn't let me. Although shipping time was fast I needed it sooner and was able to source it locally at a good price. I explained this to the seller and the seller was gracious and sent me a return label free and a refund was issued. How can you beat that? Communication was professional and courteous. This is an honest seller, so buy with confidence.

    Great seller! Very responsive and polite, with excellent communication throughout the entire process. The item arrived exactly as described, well-packaged, and in perfect condition. Fast shipping as well — received it earlier than expected. Highly recommend this seller and would gladly buy from them again!

    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 product

    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 Best replacement for outdated NGK DR8ES plugs
