Overview:
ACCEL HP Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL HP Spark Plugs are gapable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL HP Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.
Features:
- The Copper core is a better conductor than Iridium or Platinum plugs
- Copper dissipates heat much better than other materials
- "C" - Cut Design un-shrouds the spark kernel for a better burn
- Unlike Iridium or Platinum plugs, the ACCEL HP plugs are gapable
- Machine rolled threads for precise thread engagement
- One step colder than stock
- Whether using on the street or on the strip, ACCEL HP Copper Core spark plugs deliver!

Smooth Operation
Color: Brushed Aluminum, Style: No Light Kit
This Fan has exceptional airflow and operates smoothly. I use the included remote control. It took a little white to install and it’s fairly heavy, but besides that, it’s great.

Great for kids!
Color: White
I bought this stylus for the kids to use with their iPads, and it definitely gets the job done. It connects easily, charges fast, and works smoothly for drawing, writing, and playing around on apps.
The palm rejection is a big plus—it makes it a lot easier for them to use without messing up what they’re doing. It’s also pretty responsive, which I wasn’t necessarily expecting at this price.
Overall, it served its purpose well. If you’re looking for something affordable and functional for kids (or even light everyday use), this is a solid option.

Rock-Solid Apple Pencil Replacement for iPad Mini
Color: White
Despite the box arriving pretty beat up inside the Amazon packaging, the pen itself was in perfect condition and it’s been outstanding.
It works flawlessly with my iPad Mini (Gen 7, A17). The physical on/off button is a standout feature for me; the tactile click is far more satisfying and reliable than the touch-sensitive controls found on other pens.
I primarily use this stylus while flying, taking notes in the air, and it performs exactly how I need it to. The magnetic attachment is especially impressive because it’s strong enough to add real security inside my iPad case. Even in rough air, I don’t have to worry about it getting knocked loose.
I previously used a pencil from another brand that worked fine overall, but the weak (or nonexistent) magnetic hold was a dealbreaker. This one solves that problem completely and when it came time to buying a new pencil because I lost the old one, this was my choice.
If you’re looking for a dependable, well-built Apple Pencil replacement with a solid magnetic connection and a satisfying physical control, this is an easy recommendation. You also CANNOT go wrong with the price!
