M-Series Super Fire Spark Plugs
HKS M-Series spark plugs are high performance Iridium plugs designed to provide improved ignition performance, durability and anti-carbon build-up.
- 0.6mm Iridium Alloy Center Electrode
- Outer Electrode with Platinum Chip
- Short Type Outer Electrode (Anti-Vibration)
- Thermal Edge
- Spark Support Gap
M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.
The Iridium alloy is used because of its durability and reliability. On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity. With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration. The Iridium plugs are available for multiple applications and offered in "colder" heat ranges of 7 and up and specifically for rotary, heat ranges of 9 and up are offered.

Excellent, prompt, zero hassle protection
I purchased a nice 3D printer for my grandson. He was thrilled and he and his dad used it frequently. The printer developed a serious problem but, thankfully, I had also purchased a three-year protection plan with Asurion. We shipped the printer to Asurion via UPS since they readily agreed to repair it or refund the purchase price. After only a few days, Asurion emailed me that the printer was not repairable. They sent me a link that enabled me to send the full purchase price to my Amazon account. I used it to purchase another printer. I am happy and my grandson is thrilled! I should add that the extended protection did not cover sales tax, nor did it cover shipping cost.

Strongly recommend
I recently used the services of this company, and I was completely satisfied. They work very professionally: whenever I reached out, they quickly resolved any issues. I strongly recommend that anyone who purchases electronic devices register their product with this insurance. It is truly reliable.

Cheap Insurance - Easy Claims Process!
I bought this warranty plan for a Dell monitor about 3.5 years ago. About a month ago, it started to give me some intermittent problems (very fast flickering & image retention). I tried everything I could to troubleshoot the issue, but it just kept coming back.
I had some issues with logging into my Asurion account because I used an EDU email, which I no longer have access to. I sent a message to Asurion here on Amazon and they sent me my plan details and everything I needed to make a claim within 24 hrs.
Once I was able to log into my account online, the claims process couldn't be faster/easier. I used the chat function and provided the rep with the issues I was having with my monitor. The rep immediately emailed me a pre-paid UPS label to send my monitor to one of their repair facilities. I got another email when my monitor was received stating that repairs could take up to 5 business days. However, the very next day I got another email stating that my monitor couldn't be repaired and they would be reimbursing me the full purchase price. I received another email with an Amazon gift card for the full price of the monitor within minutes.
This is my first experience with Asurion and I'm very impressed. The customer service is top notch. If I ever buy another expensive electronic item from Amazon, I'm definitely buying an extended warranty from Asurion.

Better pricing than BestBuy’s Geek Squad extended warranty!
Asurion is on of the best extended warranty put there! bar none! I used to buy only from BestBuy because of their Geek Squad extended warranty. But it’s way more expensive compared to Asurion. although with Asurion they require so much paper work and pictures first.

They refunded the amount. We just had to send it to them 2 times before they did.
We bought a printer and it was having issues from the beginning. We thought at first it had to do with the WIFI, so we didn't say anything, but then more things were going wrong. I talked to the manufacturer, who said it needed to be replaced but we had to go through Asurion. Asurion "fixed" it and sent it back but we had our doubts. Sure enough, it was within the same month we were sending it in again.
This time they just gave us an amazon gift card for the entire amount we had paid. Thankful for the warranty. They ultimately did the right thing, I just wish we could have gotten it done faster.
