Description
APR Iridium Pro Spark Plugs (Set of 6) - 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.

Good quality
Size: 9*3*2 Inches, Color: Grey(2PCS)
They are good quality, no signs of rusting or flaking, & are built very sturdy. The measurements are a little inaccurate due to the tapered edges from bottom to top, so it may not fit as expected which happened in my case. The attachment edges don’t pair to other brands of organizers well so don’t expect them to stay attached. Nonetheless, worth the money for its need.

Excellent as Bird Feeders
Size: 12*3*2 Inches, Color: Black(2PCS)
Purchased these to sit on top of our trellis as bird feeders. The holes are large enough for zip ties and provide excellent aeration and drainage.

Good quality
Size: 9*3*2 Inches, Color: Grey(2PCS)
Unfortunately these did not work for me due to the shape (smaller at the bottom, which wasted space I needed). Looks like good quality.
