Reviews of APR spark plug

Unfortunately the new plugs and coils made no difference I’m still experiencing the same startup issue and it seems like the new coils and plugs may have made it act worse.

I hate ngk ngl my sparks were corroded as hell using ngk, I swapped over to Apr sparks since I’m tuned by them and they work amazing.

I’m running them on stage 3 with no issues APR Z1003100 APR Iridium Pro Spark Plugs - 14x26.5x16mm - Heat Range 9

Forgot to mention that I replaced the RS7 plugs with some APR plugs I had purchased. The gaps of the RS7 plugs were all either out of spec or on the cusp. The APR plugs are another heat range colder than the RS7s

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.

If you look at the other forum post u will notice that Pete alreAdy dynod them and noticed a difference. oh and car runs amazing @ .042
