Starts alot easier and faster, better horsepower because of a better and more efficient burn in the cylinders now. haven't checked fuel mileage yet but I imagine it will go up a couple mpg. I am totally pleased with the purchase. I like these better than the NGK plugs. Don ### ⭐ Did not fit, Amazon fit tool does not work *by D***I on Reviewed in the United States 🇺🇸 on August 16, 2022* I wish I could say I put these on and they worked great, however they did not fit my application as the “fit tool” on Amazon said they would. I begin with the return process through Amazon to find that I would have to pay nearly half the price of the product to return them. Totally not worth it, that’s money out of my pocket for Amazons mistake, not mine nor the sellers. I could understand if the Amazon fit tool told me that it wasn’t a fit and I bought it anyway only to find it not to fit, then yeah sure I would foot the bill for that. ### ⭐⭐⭐⭐⭐ Even though the cataloging of Amazon's related parts for my ... *by L***Y on Reviewed in the United States 🇺🇸 on October 21, 2015* Even though the cataloging of Amazon's related parts for my Harley Davidson Sportster said that these plugs did not fit my motorcycle, THEY DO. By using other web sites I found that these do fit and work well. I noticed a improvement right away in the performance of my bike. Quicker acceleration and the engine runs smoother. I have Iridium in two other vehicles and noticed the same thing and they last longer. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/12508597-5308-spark-plug](https://www.desertcart.gr/products/12508597-5308-spark-plug) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-17*
