APR Iridium Pro Spark Plugs - 12x26.5x14mmAPR Iridium Pro Spark Plugs are the excellent upgrade for tuned engines. Our spark plugs are made from Iridium, which is one of the strongest materials you can use in this type of application. They run cooler, resist preignition, last longer than other materials with higher melting points, and even require less voltage to produce a strong spark. The electrode is harder and stronger than other materials and with its copper core can dissipate heat more
APR Iridium Pro Spark Plugs are the excellent upgrade for tuned engines. Our spark plugs are made from Iridium, which is one of the strongest materials you can use in this type of application. They run cooler, resist preignition, last longer than other materials with higher melting points, and even require less voltage to produce a strong spark. The electrode is harder and stronger than other materials and with its copper core can dissipate heat more easily, is better protected from melting, cracking, and other limitations found with standard plugs. These plugs were designed for use on tuned and higher output vehicles that benefit from a plug cooler than the factory heat range. They are great for high boost, high cylinder pressure, high cylinder temperatures, and high power situations, and they pair nicely with a set of APR ignition coils, where applicable.
Features:
- Heat range 10 spark plug (Similar: Bosch 2, Brisk 8, Denso 31, and NGK 10)
- 152% higher melting point than silver, 125% higher than copper, and 38% higher than platinum.
- Stronger than copper and platinum
- Designed for high performance / tuned vehicle applications
- Non-projected insulator design
- Lower required supplied voltage
- Cooler operating temperature than stock plugs
- Optimized electrode design for hard to ignite fuels, such as ethanol

Best Wine Opener We’ve Tried
Color: Black
My husband and I like to think of ourselves as wine connoisseurs, and over the years we’ve been through dozens of wine openers. So far, this one is our favorite. It’s pure magic—smooth, easy, and reliable every time. The charging base keeps everything organized. We’ve been using it for several months now without a single issue. It feels well-made and has definitely earned a permanent spot on our counter. It works so seamlessly that now we both want to open the wine.

Game Changer for Wine Lovers
Color: 8-in-1 Silver, Size: Rechargeable
Circle Joy Electric Wine Bottle Opener and I’m honestly really impressed.
Setup was super simple, and it works exactly as advertised—just place it on the bottle, press a button, and the cork comes out smoothly in seconds. No struggling, no broken corks, and no mess. It makes opening wine feel effortless and a lot more enjoyable.
I also love the sleek design—it looks modern and feels sturdy, not cheap. If you have the set with accessories, the extras like the foil cutter and pourer are a nice bonus and actually useful.
Overall, this is a great little gadget, especially if you open wine often or just want something convenient and easy to use. Definitely a solid buy or even a nice gift idea.
