Overview
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

- Cooler operating temperature than stock plugs
- Optimized electrode design for hard to ignite fuels, such as ethanol

Indestructible my shiny hiney!! Dog had it destroyed in 6 hours. Waste of $$$
Color: Blue Cow
I bought this blue buffalo dog stuffy toy for my medium sized dog. It says it is for "heavy chewers" and she really isn't a heavy chewer. My German shepherd was a heavy chewer. This little dog isn't. So this toy should have lasted her a couple of weeks at best.
NOPE! NOT EVEN CLOSE!!
She had it for about 6 hours before the seams were busting open and stuffing scattered all over my house. 6 FREAKING HOURS!!!
I'm very upset over this and my son threw it away before I could tell him to let me return it. So that's $6.99 down the drain.
Indestructible my ass. Waste of money and lots of lies on the page. Phooey!

Cute but underwhelmed by the size.

Grump lobster toy
Color: Red Lobster
My girl blood-eagled this poor thing within minutes but she had one heck of a time doing it! If you're looking for durable, this probably isn't for you. If, however, you're looking for some quality entertainment for you and your dog, look no further. A little reconstruction and ol' Larry was ready for round two of being eviscerated. Solid toy, real cute.

Not a terrible toy
Color: Blue Cow
Not a terrible product, but for a super sure it doesn’t last very long. It’s cute, but this is meant for definitely a small two small medium dog.
