2011-2016 GM 6.6L DURAMAX LML (650HP)
The Fleece fpeFPE-LML-CP3-WP LML CP3 Conversion Kit with CP3K Pump for your 2011-2016 GM 6.6L Duramax is designed to convert your stock CP4 to a CP3. Why convert your LML's Fuel System from a CP4 to a CP3? The stock CP4 is only capable of supporting up to ~500rwhp. The included Fleece Performance CP3K is capable of supporting 650 rwhp in conjuction with the piezoelectric injectors. The CP4 was introduced as a cost reduction to the LML platform since a smaller amount of fuel is required when running the more efficient piezoelectric injectors. Since its introduction it has proven to be less reliable and less capable than the CP3 used in previous duramax platforms.
FEATURES:
Convert CP4 To CP3
Includes Fleece CP3K CP3 Pump
Increased Reliability & Performance

Sound is great and easy to hook up
Configuration: Fire TV Soundbar
It took a total of two minutes to have this thing powered up and working on my TV. For such a low price, I could not believe the sound that this thing puts out in a large bedroom 18’X21’. With being able to select the different sound on the equalizer, it really helped make the sound sound like a much more expensive unit. I listened to music, movies, and the news and they all sound great. I don’t know why this thing got negative reviews but for the size, price and not having a sub, I have never heard a better sounding one.
You will not be disappointed, unless you are a serious audio nerd. I would definitely buy another one if need be.

Asurion worked when needed!
My faithful dust buster broke and the nozzle wouldn't stay attached to the vacuum. I used my Asurion extension and they took care of it quickly with no hassle.
Thanks

Great coverage, easy to use, quick response to requests
Great service. Very easy to request and quick to receive a resolution. Their website is a bit confusing, it seems to default to mobile phone inquiries, there is another section to request service on other items. I will definitely purchase protection in the future.

I’m really happy I bought this protection
I had a steam mop that did a great job cleaning my floor and Lazy Boy. After 2 years of using it the mop didn’t work anymore. I remember I bought this protection. I was shocked how easy and fast the claim was paid. I was able to buy a new mop and get another 3 year warranty. I would definitely recommend this for household appliances.

Extended Warranty is worth it.
So glad I took out a three year warranty, my Shark Steam Mop stopped steaming.
Asurion refunded me with Amazon credit.
Thank you.
