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, 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 9 spark plug (Similar: Bosch 3, Brisk 10, Denso 27, and NGK 9)
- 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
- Resists preignition better than stock plugs
- Perfect for upgraded APR vehicles
- An excellent match for APR ignition coils
- Thread reach: 26.5mm
- Thread diameter: 14mm
- Hexagon: 16mm
- Seat Type: Gasket
- Install Torque: 25 Nm

Not a big fan
Oily and doesn’t absorb well. The scent was very overpowered with honey.

Amazing product
I have just purchased my 7th jar! I absolutely love this product...and its American made! It leaves my skin soft, radiant and glowing! I didn't tell anyone about using it and people started asking me what I was doing differently. I get complements about my youthful glow! This company makes an amazing product and I hope that it will always be available! I have friends and family members hooked on it now. My mom just dropped a stocking stuffer hint to me tonight for another jar!

Legit balm. Not whipped. Made in USA.
Legit tallow balm. Not whipped. I love this stuff. It's the only thing that soothes, softens, and relieves my dry skin in the winter. Also made in USA, which is a priority for me.

Great winter moisturizer! Not greasy & absorbs well!
I needed a moisturizer that would last in colder weather. My skin is oily/normal and works well with my other facial products. I strictly use The Ordinary products and add this at the end to seal in the moisture. Pretty surprised how quickly this absorbed in to my skin. Has no scent and melts quickly on finger tips. I use it on my face and heels of my feet. Honestly love this addition to my fall/winter skincare routine. A little goes a long way! I have been using for a month now with great results. Definitely a great buy!

Great product if you can actually use it
Of the 4 orders I've placed for this lotion, only 2 have come perfectly. One of them came leaking tallow out of the container and package, and then it's replacement arrived with the jar completely shattered.
The tallow itself is so hydrating and smells great, but if the company itself needs to fix it's packaging.
