Description

2011-2016 LML CP3 Conversion Kit with PowerFlo 750Why convert your LML's Fuel System from a CP4 to a CP3? The stock CP4 is only capable of supporting up to ~500 RWHP. A CP3K is capable of supporting 600+ RWHP in conjunction with the piezoelectric injectors. The reliable and proven PowerFlo 750 is capable of supporting nearly 850+ RWHP. 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.

Why convert your LML's Fuel System from a CP4 to a CP3?

  • The stock CP4 is only capable of supporting up to ~500 RWHP. A CP3K is capable of supporting 600+ RWHP in conjunction with the piezoelectric injectors. The reliable and proven PowerFlo 750 is capable of supporting nearly 850+ RWHP.
  • 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, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms.

  • High Pressure Fuel Rail Line
  • Fuel Rail Plug and Nut
  • CP3 Block Adapter with O-ring
  • (3) CP3 Block Adapter Bolts (Flange Head, M8x1.25x35mm)

Whoa - 2020 Suburban
Size: 9005+H11
Finally decided to replace the halogens on my 2020 Suburban, and the difference is literally night and day. I do a lot of early morning driving and suffered for 4 years with the halogens. If this is you, stop suffering and upgrade your lights. You will be glad you did. The market is flooded with these LED upgrades, I used AI to help me determine the right fit, best value for the money, and most importantly something really bright. It returned a few options and this was one of them. I can’t speak to the longevity or durability yet, but the results are amazing. The fit is direct replacements, and they look great. Installation was straightforward but did take about 30 mins or so. Basic tools needed for the suburban, 10mm socket, flathead screwdriver, and a panel pry tool was helpful.

Fit 2015 228xi even tho not exact shape as oem
The large clip that has the feet that point out in second position(ballet term, google it so you see what the orientation looks like) fits with much more ease than you’ll think. It won’t hook into its oem place but the top flat squared off part will hook to the interior roof of the that general area snuggly. Spent 1.5 hours trying to bend the smaller ones into a similar shape to oem and then it hit me. The bigger one would probably be large enough to catch the top of the bulb housing. Learn from me. Try the big one.
