Today after doing my rebuild on my M54 engine I will be switching from Platinium's power plugs back to my iridium ones which is actually a upgrade if you want to get ones like that. They do make a difference. It's small but there is a difference. First difference, the tip in Platinium ones is made of Platinium which can withstand temperatures up to 1700 roughly about 1700 Celsius. That's the meltdown point where iridium can withstand 2400 Celsius. This part creates hotter, fatter spark. So the combustion is better. Maybe economy but power is not as well. That's why I like them. I'm going to switch them back today. And also I will do a small quick test to show you what's the difference. So here's the part of my test is to run the car with the OEM Platinium's power plugs and read the vibration. Which is average about 0.60. The maximum is 1.9. Actually, following the phone, it's 2.5. We're going to keep it for 2 minutes. I'm going to check the spark plugs and check again. So I won't be removing that cover for the cabin filter because I got this tool. So I can reach the end to spark plugs. You missed all the good fun watching me changing the spark plugs but I want to keep that video quick and simple. So we're going to begin the test again. So for now, the average is 58. Maximum is 55. We're going to wait 2 minutes. Maximum jumped to 2.16. So the test is finished. The engine is running a bit smoother. There's a difference on idle, same as on acceleration. So guys, pretty simple test with smartphone Platinium. I don't know what this figure means. 69 average, 0.69 average, 2.5 nearly maximum, 0.61 average with a radium and 2.16 maximum. So yeah, they do run the engine smoother. They give you slightly more power that feeling. And they do work. I like them. I use them and I recommend you. I will give you part numbers in the description for the OEM and upgrade. See you next time.
