I chose this specific set based on the great desertcart ratings, reviews, and highly competitive pricing. SUCCESSFULLY SOLVED ENGINE MISFIRES Before putting these in, my truck was idling roughly and had actually thrown a Check Engine Light (CEL) code for a cylinder misfire. The impact of these new plugs was immediate. As soon as they were installed and fired up, the engine sounded significantly better and idled smoothly. Best of all, the cylinder misfire code was completely cleared, and the dashboard light went away for good. I have since upgraded to a newer truck, but these plugs ran perfectly with zero issues for the remainder of the time I owned that vehicle. PRE-GAPPED ACCURACY AND INSTALL RECON Out of the box, the plugs were consistently engineered. The gaps were completely spot-on and did not require any manual adjustment before installation, which saved a lot of time. The physical installation itself can be tough, but that is entirely due to the tight clearance layout of the Ram engine bay rather than the plugs themselves. The front sets of plugs are manageable to swap out in a home garage, but getting to the furthest sets of plugs tucked at the very back of the firewall is incredibly tight. I ended up handling the most myself and hiring a local professional to knock out the cramped rear plugs to save the headache. PROS -Instantly cleared a cylinder misfire Check Engine Light and restored smooth idling. -Arrived perfectly pre-gapped and required zero manual adjustments out of the box. -Threads and terminals lined up flawlessly with the factory Hemi ignition packs. -Exceptional budget-friendly price point compared to expensive auto parts store brands. CONS -None. Swapping the rear plugs on a Ram is a physical challenge, but the part quality itself is 5-star. FINAL VERDICT If your high-mileage Hemi is starting to idle rough or throw misfire codes, this iridium set is a phenomenal, cost-effective fix. They perform exactly as they should and save you a massive amount of money over big-name legacy brands. Highly recommended! Review: G-Power Platinum Spark Plugs - I recently purchased the NGK # 3186 G-Power Platinum Spark Plugs for my vehicle, and I couldn't be more satisfied with their performance. Here’s a breakdown of my experience based on several key aspects: **Functionality:** These spark plugs have significantly improved the engine's performance. I've noticed a smoother start and better acceleration since installing them. The improved combustion efficiency has also led to a slight increase in fuel economy, which is a bonus. **Quality:** NGK is a brand synonymous with reliability, and the quality of these spark plugs is no exception. The platinum construction ensures durability and a longer lifespan compared to standard copper plugs. They feel robust and well-made, providing confidence in their longevity. **Look:** While spark plugs aren't typically the focal point of a vehicle’s aesthetics, I must admit that the shiny platinum finish gives them a sleek and professional appearance. It’s always nice to see quality craftsmanship, even in components that are tucked away under the hood. **Value for Money:** Considering their performance and durability, these spark plugs offer excellent value for money. They may be slightly pricier than some alternatives, but the benefits in fuel efficiency and engine performance make them worth every penny. You truly get what you pay for with NGK products. **Fit:** Installation was a breeze. These spark plugs fit perfectly in my engine, with no issues to report. It’s reassuring to know that I am using a product designed specifically for my vehicle, ensuring optimal contact and performance. **Gap Accuracy:** One of the standout features of the NGK # 3186 G-Power Platinum Spark Plugs is their precise gap accuracy. The .044 inch gap was spot-on, leading to a perfect spark and optimal combustion. I didn’t have to make any adjustments, which made installation quick and easy. In conclusion, I highly recommend the NGK # 3186 G-Power Platinum Spark Plugs for anyone looking to upgrade their ignition system.

Money is tight at the moment, so I am on a strict budget. However, I have to keep my truck running for work and spark plugs were needed to help the vehicle perform better. I was not expecting much, but felt these would be better than the old ones I was running on and I was also thankful for the price. My truck is running so much better. Extremely pleased with how my truck is performing smoothly after installing these Iridium Spark Plugs. The installation and fit were perfect. The difficulty in changing the spark plugs came in the design and build of the truck and not the Spark Plugs. The only negative thing I have to say, is that these do not come gapped anywhere to where they are suppose to be, so be prepared for that. ## Frequently Bought Together - BDFHYK Set of 8 Iridium Spark Plug Compatible with Expedition F150 F250 F350 F450, Compatible with Lincoln Mark LT Navigator,5.4L 6.8L V8 V10 Engine Replacement for SP515 SP546 - Marsram Ignition Coil Pack FD508 for 2004 2005 2006 2007 2008 Ford F150 Expedition Explorer F350 F250 F450 Super Duty Mustang 5.4L 4.6L Lincoln Navigator Mark LT 6.8L V8 V10 for DG511 8pcs - Permatex 22058 Dielectric Tune-Up Grease, 3oz. - High Performance Dielectric Grease Used To Protect Terminals, Spark Plugs, Wiring And Other Electrical Connections Against Salt, Dirt, And Corrosion --- ## 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.hr/products/496623517-bdfhyk-sp546-iridium-spark-plugs-8-pack-for-ford-f](https://www.desertcart.hr/products/496623517-bdfhyk-sp546-iridium-spark-plugs-8-pack-for-ford-f) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-04*
