Great upgrade for my g56. Really cold weather it takes a little bit to warm up but keeps the gear roll over noise down.

Excellent

Used and love schaffer products in the past!

They shipped fast and the glow plugs heat up fast and it starts right up with no problems

Awesome product. The installation was very easy, although the instructions weren't exactly clear. I watched a YouTube video and it was a lot easier. The price was great. The shipping was quick. The information about the different programs they outlined on the website was very helpful.
